摘要

Abstract

Developing efficient

stable and sustainable photocatalysts for water splitting is one of the most significant methods for generating hydrogen. Conjugated microporous polymers

as a new type of organic semiconductor photocatalyst

have adjustable bandgaps and high specific surface areas

and can be synthesized using diverse methods. In this work

we report the design and synthesis of a series of pyridyl conjugated microporous polymers (PCMPs) utilizing polycondensation of aromatic aldehydes and aromatic ketones in the presence of ammonium acetate. PCMPs with different chemical structures were synthesized

via

adjusting monomers with different geometries and contents of nitrogen element

which could adjust the bandgap and photocatalytic performance. Photocatalytic hydrogen evolution rate (HER) up to 1198.9 μmol·h

−1

·g

−1

was achieved on the optimized polymer with a specific surface area of 312 m

·g

−1

under UV-Vis light irradiation (

320 nm). This metal-free synthetic method provides a new avenue to preparing an efficient photocatalyst for hydrogen evolution.
