Photocatalysis is a promising strategy to tackle the problem of energy and pollution. To date, it is driven by external physical light sources, which are not always applicable in some practical applications. In this research, we explore the possibility of chemiluminescence as internal light to drive the photocatalysis reaction using graphitic carbon nitride as the catalyst. A biphasic reaction is employed where the light-generating reaction occurs in the oil phase, and the photocatalysis mainly takes place in the aqueous phase. This system exhibits efficient catalytic activity in degradation of rhodamine B, methyl orange, and methylene blue. The proof-of-concept design of chemiluminescence-driven photocatalysis provides an alternative strategy to address environmental issues and other photochemistry reactions.
光催化是解决能源和污染问题的一种很有前景的策略。迄今为止,它是由外部物理光源驱动的,而这些光源在某些实际应用中并不总是适用。在本研究中,我们探索了利用石墨相氮化碳作为催化剂,将化学发光作为内部光源来驱动光催化反应的可能性。采用双相反应,其中发光反应发生在油相中,而光催化主要发生在水相中。该体系在罗丹明B、甲基橙和亚甲基蓝的降解中表现出高效的催化活性。化学发光驱动光催化的概念验证设计为解决环境问题和其他光化学反应提供了一种替代策略。
