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

Herein we used a rapid microwave (MW)-assisted heating synthesis to produce a crystalline polyimide inminutes. 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 H-2 production under visible light irradiation.
