The PhD in question has strong ties to sustainable and green chemistry, given that these types of catalytic processes offer an affordable way to utilize the CO2 produced when fossil fuels are burned, CO2 is a key greenhouse gas that directly contributes to climate change . A number of possible reduction targets have already been identified in CO, formic acid and methanol. CO is an important feedstock for the Fischer-Tropsch process, while both methanol and formic acid are key components in new fuel cells that could one day be used in the auto-motive industry. We will be studying the synthesis of novel and affordable catalysts based on Group 6 and 7 metal centres which bear a diverse range of ligands, these catalysts can also, in principle, be coupled to a photo-anode; allowing light-driven CO2 reduction to occur. Also studied will be the behaviour of these catalysts in ionic liquids which can be vastly different to their behaviour in normal solutions. Of equal interest is the surface/interface chemistry of the catalysts when bound by phosphate anchors to solid TiO2 and the co-operative effects of having a molecular catalyst and redox-active nanoparticles of copper in the same system. Of course, the PhD will have a strong foundation in molecular scale analytical techniques, particularly with regard to spectroelectrochemistry which can offer real insight into the processes that are occurring during the reduction of CO2. Infrared, UV-Vis, NMR and EPR spectroscopy will all play a critical role in structure determination.

鉴于这些类型的催化过程提供了一种负担得起的利用化石燃料燃烧时产生的二氧化碳的方式，二氧化碳是直接导致气候变化的一种关键温室气体，因此上述博士学位与可持续和绿色化学有着密切的联系。已经在一氧化碳、甲酸和甲醇中确定了一些可能的还原目标。CO是费托工艺的重要原料，而甲醇和甲酸都是新型燃料电池的关键成分，有朝一日可能会用于汽车工业。我们将研究合成基于第6和第7族金属中心的新型和负担得起的催化剂，这些金属中心承载着各种不同的配体，这些催化剂原则上也可以耦合到光阳极上；允许光驱动的二氧化碳还原。还将研究这些催化剂在离子液体中的行为，这可能与它们在正常溶液中的行为有很大不同。同样令人感兴趣的是，当催化剂被磷酸锚链结合到固体二氧化钛上时，催化剂的表面/界面化学，以及在同一体系中具有分子催化剂和氧化还原活性的铜纳米颗粒的协同效应。当然，博士学位将在分子尺度分析技术方面拥有坚实的基础，特别是在光谱电化学方面，这可以提供对二氧化碳减少过程中发生的过程的真正洞察。红外光谱、紫外-可见光谱、核磁共振光谱和电子顺磁共振光谱都将在结构确定中发挥关键作用。
