光催化小分子烷烃碳氢键活化和转化研究 英语
English:
The research on photocatalytic activation and transformation of small molecule alkanes has attracted significant attention due to the sustainable and efficient utilization of hydrocarbons. Traditional methods for alkane activation, such as high temperature and high-pressure conditions, often lead to low selectivity and energy consumption. In contrast, photocatalytic activation offers a more environmentally friendly and mild approach to break the strong C-H bonds in alkanes under ambient conditions. The use of semiconductor photocatalysts, such as titanium dioxide and g-C3N4, can effectively generate electron-hole pairs under light irradiation, leading to the formation of highly reactive oxygen species for alkane activation. Furthermore, the combination of co-catalysts, such as noble metal nanoparticles or molecular co-catalysts, can greatly enhance the efficiency and selectivity of alkane transformation. Overall, the development of photocatalytic methods for alkane activation and transformation holds great potential for the sustainable utilization of abundant hydrocarbon resources.
