This project aims to improve the performance and longevity of molecular photocatalysts to produce hydrogen from water and visible light. Sustainable alternatives to fossils fuels, such as hydrogen, are critical to minimising the effects of climate change. This project expects to use innovative experimental techniques to reveal the causes of degradation in key intermediates of the photocatalytic reaction. Understanding these detrimental pathways can then direct the design of new catalysts with enhanced stability and activity. The fundamental chemistry explored in this project should advance breakthroughs in artificial photosynthesis and provide cleaner methods of hydrogen production under mild conditions, using earth-abundant catalysts.

该项目旨在提高分子光催化剂的性能和寿命，从而从水和可见光中产生氢。化石燃料（例如氢）的可持续替代品对于最大程度地减少气候变化的影响至关重要。该项目希望使用创新的实验技术揭示了光催化反应的关键中间体中降解的原因。然后，了解这些有害途径可以指导具有增强稳定性和活性的新催化剂的设计。该项目中探讨的基本化学反应应提高人工光合作用的突破，并使用含量丰富的催化剂在轻度条件下提供更清洁的氢生产方法。
