Towards Global Artificial Photosynthesis (Global Solar Fuels): Energy, Nanochemistry, and Governance 
blank image
Thomas Faunce blank image
pp. 557-563
blank image

This introduction sets the papers collected for this special edition (that arose from the 2011 Lord Howe Island conference on Global Artificial Photosynthesis) in the context of the scientific and governance challenges for a Global Solar Fuels project. This special edition represents the first dedicated to such a theme and its significance is highlighted by the fact that 2012 is the United Nations’ Year of Sustainable Energy for All.

Molecular Chemistry for Solar Fuels: From Natural to Artificial Photosynthesis 
blank image
Ann Magnuson and Stenbjörn Styring blank image
pp. 564-572
blank image

Our present energy system stands on black roots; one decade into the new century fossil fuel sources are still more than 80 % of our primary energy. This paper discusses why we need to develop means to produce truly sustainable fuels, and proposes solar energy as the major renewable energy source to feed from.

Smith , Leone Spiccia , Pawel Wagner , Gordon G. Wallace , Bjorn Winther-Jensen and Orawan Winther-Jensen blank image

This article reviews some of the recent work in the field of water oxidation and reduction catalysts by fellows and associates of the Australian Research Council’s Centre of Excellence for Electromaterials Science (ACES) at Monash University and the University of Wollongong, as well as their collaborators. This work is focussed on the development of a hydrogen-based energy technology. Topics discussed include: (1) the role and apparent relevance of the cubane structure of the Photosystem II - Water Oxidation Complex (PSII-WOC) in non-biological homogeneous and heterogeneous water oxidation catalysts, (2) light-activated conducting polymer catalysts for both water oxidation and reduction, and (3) porphyrin-based light harvesters and catalysts.

Structure, Dynamics, and Function in the Major Light-Harvesting Complex of Photosystem II 
blank image
Gabriela S. Schlau-Cohen and Graham R. Fleming blank image
pp. 583-590
blank image

In natural light-harvesting systems, pigment-protein complexes (PPC) convert sunlight to chemical energy with near unity quantum efficiency. Studies using two-dimensional electronic spectroscopy (2DES) provide an incisive tool to probe the electronic, energetic, and spatial landscapes that enable the efficiency observed in photosynthetic light-harvesting. We review design principles of PPCs learned from the information contained within 2D spectra.

The Chemical Problem of Energy Change: Multi-Electron Processes 
blank image
Joseph L. Hughes and Elmars Krausz blank image
pp. 591-596
blank image

Feedback mechanisms originating from autocatalytic events near the end of an electron transfer chain can improve the rate of electron transfer nearer to the beginning, leading to cooperative multi-electron transfer.

The Biomimetic Inspiration for Renewable Hydrogen Fuel Production from Water Oxidation within Artificial Photosynthesis 
blank image
Ron J. Pace and Rob Stranger blank image
pp. 597-607
blank image

The Mn4/Ca centre in Photosystem II is the most effective anodic water oxidizing catalyst known and operates close to the thermodynamic limit. This performance derives from redox properties of Mn in the oxidation states II–IV, which are uniquely ‘tuned’ to allow function with minimum overvoltage. Possible strategies to exploit this for efficient, biomimetic electrolytic H2 generation are discussed.

Preparation and Characterization of Catalysts for Clean Energy: A Challenge for X-rays and Electrons 
blank image
Rosalie K. Hocking , Shery L. Y. Chang , Douglas R. MacFarlane and Leone Spiccia blank image
pp. 608-614
blank image

Key to elucidating the origin of catalytic activity and improving catalyst design is determining molecular-level structure, in both the ‘resting state’ and in the functioning ‘active state’ of the catalysts. Herein, we explore some of the analytical challenges important for designing and studying new catalytic materials for making and using hydrogen.

Active Site Elucidation in Heterogeneous Catalysis via In Situ X-Ray Spectroscopies 
blank image
Adam F. Lee blank image
pp. 615-623
blank image

Despite their importance in energy and chemical technologies, heterogeneous catalysts are often viewed as a ‘black box’, with their design bordering on alchemy. Advanced in situ X-ray spectroscopies are now enabling scientists to peer inside these functional nanomaterials and understand the inner workings of catalysts in action.

pp. 624-632
blank image

Surface modification of TiO2 with molecular metal oxide clusters is demonstrated to be a promising approach for providing it with visible-light responsiveness or enhancing the UV response.

On the Stability of Water Oxidation Catalysts: Challenges and Prospects 
blank image
Alex Izgorodin , Orawan Winther-Jensen and Douglas R. MacFarlane blank image
pp. 638-642
blank image

Future requirements for water splitting technologies need highly efficient water oxidation catalysts that are sufficiently stable for operation over many years. In this paper, we discuss some of the chemical and thermodynamic challenges confronting this goal, as well as some of the strategies that are available to overcome them.

Perspectives for Photobiology in Molecular Solar Fuels 
blank image
Kastoori Hingorani and Warwick Hillier blank image
pp. 643-651
blank image

Solar fuels are initiatives to harness sunlight and to generate storable fuels. Microbes can be genetically reprogrammed to produce algal fuels in the form of hydrocarbons and biodiesel. Artificial photosynthesis using proteins can also be produced. The goal with these systems is to use renewable solar energy and to catalyse energy conversion into a chemical bond. The paper outlines options and possible outcomes with solar energy conversion using photobiology.

Engineering Enzymes for Energy Production 
blank image
David L. Ollis , Jian-Wei Liu and Bradley J. Stevenson blank image
pp. 652-655
blank image

Enzymes allow efficient conversion of biomass into useful chemical energy; however, they are seldom optimized for reaction conditions in biotechnology. Directed molecular evolution can be used to generate enzymes suited for new environments. As an example, we illustrate how yeast pyruvate decarboxylase 1 has been enhanced for in vitro fermentative glycolysis.

The Challenge of Storage in the Hydrogen Energy Cycle: Nanostructured Hydrides as a Potential Solution 
blank image
James M. Hanlon , Hazel Reardon , Nuria Tapia-Ruiz and Duncan H. Gregory blank image
pp. 656-671
blank image

Nanochemical design methods offer routes to overcome the thermodynamic and kinetic hurdles associated with solid state storage in hydrides. In this review we discuss strategies of nanosizing, nanoconfinement, morphological/dimensional control, and application of nanoadditives on the hydrogen storage performance of metal hydrides and the potential role of such materials in a sustainable hydrogen cycle.

A New Quinoxalinyl-Substituted Nitronyl Nitroxide Radical and its Five-Spin CuII and Four-Spin MnII Complexes: Syntheses, Crystal Structures, and Magnetic Properties 
blank image
Chao Wang , Yue Ma , Yali Wang , Qinglun Wang , Licun Li , Peng Cheng and Daizheng Liao blank image
pp. 672-679
blank image

A new radical of 2-(2-quinoxalinyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide was first designed and synthesised to afford four coordination sites to construct CuII and MnII complexes with more complicated structures and magnetic properties.

Novel Phosphopeptides as Surface-Active Agents in Iron Nanoparticle Synthesis 
blank image
Raoul Peltier , Wai Ruu Siah , Grant V. M. Williams , Margaret A. Brimble , Richard D. Tilley and David E. Williams blank image
pp. 680-685
blank image

Wet chemical techniques are attractive methods for the preparation of metal nanoparticles. Here, we report the dramatic effect of rationally-designed phosphopeptides on the size, shape and magnetic properties of iron-iron oxide core-shell nanoparticles prepared in a one-pot synthesis by sodium borohydride reduction of an iron salt. These phosphopeptides are effective at small ratios of peptide to metal, in contrast to the behaviour of conventional surfactants, which must be added at high concentration to control the particle growth.

Chlorination of N,N′-di(2-pyridyl)malonamides affords 4-pyridylimino-4H-pyrido[1,2-a]pyrimidines 17. Flash vacuum thermolysis of 17a causes ring opening to a valence-tautomeric ketenimine, elimination of HCl, and formation of the bis(4-methyl-2-pyridylimino)propadiene, R-N=C=C=C= N-R 20a.
