Energy is one of the most important issues of the twenty-first century, because our future supply is currently threatened by progressively decreasing fossil fuel reserves, political instability and environmental problems resulting in pollution and global warming. Renewable hydrogen, H2, is widely considered as a potential future fuel, but its cheap and efficient production is still a major unresolved practical issue. The sun provides our planet with a continuous flow of electromagnetic and carbon-free energy and it is the only energy source, which is capable of sustaining human kind's long-term energy demand. The aim of this EPSRC-funded project is the development of an efficient bio-inspired H2 production catalyst from abundant and inexpensive raw materials and its coupling to light-harvesting complexes to capture energy provided by the sun to power H2 production from water - the storage of solar energy in the chemical bond of H2.Selective and economical chemical catalysts are needed for the central chemical interconversion of energy, water and H2 if there is to be a real prospect of promoting H2 as a sustainable fuel. Commonly employed precious metal catalysts (e.g. platinum) cannot be used for H2 production in the post-fossil fuel era, because of (i) limited resources and high cost, (ii) poor reaction selectivity (e.g. energy is wasted on unwanted side-reactions), and (iii) poisoning (catalyst-killing) by trace amounts of common chemicals, e.g. carbon monoxide. Microbial life forms handle the challenging task of H2 production using bio-catalysts (hydrogenases) to drive the selective and reversible production of H2 from water at fast rates under the safe conditions of room temperature and neutral pH. The catalytic reaction centre (active site) of hydrogenases contains an iron or nickel-iron metal centre surrounded typically by cysteine, carbon monoxide and cyanide ligands. Thus, the active site of a hydrogenase is an interesting biological motif to mimic in order to build H2 production catalysts from abundant and inexpensive raw materials. This adventurous work on solar H2 production has the prospect of being a fundamental step towards large-scale water photolysis for a sustainable hydrogen economy. International (France, USA) and national (Manchester) academic as well as industrial (Evonik Industries) collaborators with expertise in enzyme biology, spectroscopy, solar cells, nanoparticles, and neutron diffraction will support this project under my guidance. In addition, this work on bio-inspired/biomimetic H2 production catalysts will also deal with wastewater treatment, the synthesis of fine chemicals, and might give us insight into how living organisms convert water into H2 on a molecular level, and reveal how the reverse reaction works: the generation of energy from H2, which is important for fuel cell applications.

能源是21世纪最重要的问题之一，因为我们未来的供应目前正受到化石燃料储备逐渐减少、政治不稳定以及造成污染和全球变暖的环境问题的威胁。可再生氢，H2，被广泛认为是一种潜在的未来燃料，但其廉价和有效的生产仍然是一个重大的悬而未决的实际问题。太阳为我们的星球提供了源源不断的电磁和无碳能源，它是唯一的能源，能够维持人类的长期能源需求。该EPSRC资助项目的目的是开发一种高效的生物启发的H2生产催化剂，该催化剂来自丰富且廉价的原材料，并将其与捕光复合物偶联以捕获太阳提供的能量，从而从水中生产H2-将太阳能储存在H2的化学键中。水和H2，如果要有促进H2作为可持续燃料的真实的前景的话。通常使用的贵金属催化剂（例如铂）不能用于后化石燃料时代的H2生产，因为（i）有限的资源和高成本，（ii）差的反应选择性（例如能量浪费在不希望的副反应上），和（iii）痕量的常见化学品（例如一氧化碳）的中毒（催化剂杀死）。微生物生命形式使用生物催化剂（氢化酶）处理具有挑战性的H2生产任务，以在室温和中性pH的安全条件下以快速的速率从水中选择性和可逆地生产H2。氢化酶的催化反应中心（活性部位）包含铁或镍铁金属中心，通常被半胱氨酸，一氧化碳和氰化物配体包围。因此，氢化酶的活性位点是一个有趣的生物基序，以模仿，以建立从丰富和廉价的原料H2生产催化剂。这项关于太阳能氢气生产的冒险工作具有前景，将成为实现可持续氢气经济的大规模水光解的基本步骤。国际（法国，美国）和国家（曼彻斯特）学术以及工业（赢创工业）合作者在酶生物学，光谱学，太阳能电池，纳米粒子和中子衍射方面的专业知识将在我的指导下支持这个项目。此外，这项关于生物启发/仿生H2生产催化剂的工作还将涉及废水处理，精细化学品的合成，并可能让我们深入了解生物体如何在分子水平上将水转化为H2，并揭示逆反应如何工作：从H2产生能量，这对燃料电池应用很重要。
