Rapid microwave-assisted green production of a crystalline polyimide for enhanced visible-light-induced photocatalytic hydrogen production

Abstract

Herein we used a rapid “microwave (MW)-assisted heating synthesis” to produce a crystalline polyimide in minutes. Importantly, the present strategy avoids the tedious washing process for the produced polyimide. Benefiting from the relatively high crystallinity, the obtained polyimide shows improved photocatalytic H₂ production under visible light irradiation.
