Conjugated nanoporous polycarbazole bearing a cobalt complex for efficient visible-light driven hydrogen evolution

Author affiliations

Abstract

A conjugated nanoporous polycarbazole (CNP) cross-linked by pyridine and coordinated to Co(III) displays high catalytic performance for visible light-driven H2 generation. The hydrogen evolution rate was up to 410 μmol g−1 h−1. Spectroscopic and electrochemistry studies indicate that the redox active cobalt reduces recombination of photoexcited-charge-carriers and enhances the transmission of photoexcited-charge, thereby enriching the catalytic activity of hybrid materials x-Co/CNP-N (x = 5, 10, 15 and 20 wt%).
