Abstract

Abstract : Hollow conjugated microporous polymer photocatalysts bearing Pd nanoparticles were engineered to show visible light-induced HERs up to 7100 μmol h −1 g −1 and AQYs up to 3.72% (@420 nm). Abstract : This work shows that the hydrogen evolution performance of conjugated microporous polymer (CMP)-based photocatalysts can be enhanced through their hollow shape engineering. Using a hollow microporous organic polymer (H-MOP) as a template, hollow Stille coupling-based CMP photocatalysts with Pd nanoparticles (H-MOP@SCMP-Pds) were prepared, showing enhanced hydrogen evolution rates up to 7100 μmol h −1 g −1 and apparent quantum yields up to 3.72% (@420 nm).
