The metal-free photocatalyst, g-C3N4, is very attractive for solar hydrogen production. Presently, g-C3N4 is mainly fabricated by the conversion of nitrogen-rich precursors at high temperature (400-600 degrees C) for a long reaction time (several hours to days). Herein we report a rapid synthetic strategy named microwave (MW)-assisted heating synthesis, which allows the highly crystalline g-C3N4 photocatalyst to be fabricated in minutes. The obtained g-C3N4 displays enhanced photocatalytic H-2 production. In addition, the described synthetic strategy is a general approach that can also be applicable to other nitrogen-rich organic precursors, such as melamine, cyanamide, and thiourea. Importantly, the present process enables scale-up production of g-C3N4 for several grams in minutes.
