Encapsulating [Mo₃S₁₃]²⁻ clusters in cationic covalent organic frameworks: enhancing stability and recyclability by converting a homogeneous photocatalyst to a heterogeneous photocatalyst

Abstract

We encapsulated anionic [Mo₃S₁₃]^2- clusters in cationic COFs (EB-COF) to obtain the novel composite photocatalytic material Mo₃S₁₃@EB-COF. Comprehensive studies indicated that the Mo₃S₁₃@EB-COF was the product of a successful conversion of a homogeneous to a heterogeneous catalyst, and exhibited excellent stability and recyclability as well as a remarkable photocatalytic hydrogen evolution rate of 13 215 μmol g^-1 h^-1 under visible-light irradiation over the course of 18 hours.
