Title: The kinetics regulation of photo-generated carriers in g-C3N4 by bulk/surface engineering towards high-efficiency photocatalytic H2 production
Abstract: Graphitic carbon nitride (g-C3N4) has been extensively studied as a metal-free and visible-light-responsive photocatalyst in the realm of solar catalysis for H2 production. The unique merits of low cost, good physicochemical stability, regulable electronic band structure and non-toxicity make g-C3N4 have significant advantages for the potential industrial application. However, it still remains great challenge to achieve critical breakthrough in H2-production efficiency due to the low ultilization of photo-generated carriers in g-C3N4. Herein, we make a summary of our previous works about the bulk/surface engineering of g-C3N4 to adjust the kinetics of photo-generated carriers for promoting photocatalytic H2 production, including precursor recrystallization, functional groups insertion, novel g-C3N4 development, nanosheets exfoliation designation, device development for surface functionation, surface reactive sites adjustment towards low-cost photocatalysis and overall water splitting. We demonstrate a series of research strategies and theories in the understanding of the structure–carriers–photocatalysis relationship of g-C3N4, which could provide a meaningful reference for developing highly efficient g-C3N4 photocatalytic systems towards solar energy conversion and industrial application.
