Singlet oxygen ( O ) is an excellent reactive oxygen species (ROSs) for the selective conversion of organic matter, especially in advanced oxidation processes (AOPs). However, due to the huge dilemma in synthesizing single-site type catalysts, the control and regulation of O generation in AOPs is still challenging and the underlying mechanism remains largely obscure. Here, taking advantage of the well-defined and flexibly tunable sites of covalent organic frameworks (COFs), we report the first achievement in precisely regulating ROSs generation in peroxymonosulfate (PMS)-based AOPs by site engineering of COFs.

However, the efficient and selective generation of O maintains a great challenge. Here, we develop a donor-acceptor structured g-CN by covalently engineering benzenetricarboxaldehyde (BTA) onto the fringe of g-CN.
