The field of photocatalysis in organic synthesis has seen a significant increase in research interest in recent years due to the appealing benefits that are associated with this branch of synthetic chemistry; photocatalysis enables unique transformations to be achieved via the light induced chemical processes which are typically inaccessible by conventional thermal approaches, while maintaining high reaction selectivity under mild conditions.1-4The novel reactivities afforded by the use of photocatalysts in synthetic organic chemistry has the further benefit of allowing small, gaseous molecules to be used as reagents in reactions. Gaseous molecules such as carbon dioxide,5-7 sulfur dioxide,8-10 methane and other small hydrocarbons11, 12 have all featured in recent publications as feedstock reagents. This is a hugely exciting research area; by using photocatalysis it is feasible to convert these abundant, and thereby potentially inexpensive, small waste molecules into building blocks for valuable synthetic target products, thereby providing an economic incentive for investing in these technologies and approaches. This field has potential for extensive further research: including the development of new photocatalysts, the discovery of novel synthetic reactions, and the testing of new experimental setups to improve the versatility of photocatalytic transformations in synthetic chemistry. Furthermore, this work will contribute to the goal of making organic chemistry more 'green': by using anthropogenic waste gases as feedstock reagents to synthesise valuable target molecules, and by developing new reactions that minimise our reliance on rare transition metals.

近年来，有机合成中的手性化合物领域的研究兴趣显著增加，这是由于与合成化学的这个分支相关的吸引人的益处;通过光诱导的化学过程实现独特的转化，这通常是常规热方法无法达到的，同时在温和的条件下保持高的反应选择性。1 - 4在合成有机化学中使用光催化剂所提供的新的反应活性具有允许小的气态分子用作反应中的试剂的进一步的益处。气体分子如二氧化碳、5-7二氧化硫、8-10甲烷和其他小烃11，12都在最近的出版物中作为原料试剂。这是一个非常令人兴奋的研究领域;通过使用碳纳米管，可以将这些丰富的，从而可能廉价的小废物分子转化为有价值的合成目标产品的构建模块，从而为投资这些技术和方法提供经济激励。该领域具有广泛的进一步研究潜力：包括开发新的光催化剂，发现新的合成反应，以及测试新的实验装置，以提高合成化学中光催化转化的多功能性。此外，这项工作将有助于实现使有机化学更加“绿色”的目标：通过使用人为废气作为原料试剂来合成有价值的目标分子，并通过开发新的反应来最大限度地减少我们对稀有过渡金属的依赖。
