摘要：
The hydrogen evolution reaction (HER) may contribute substantially to energy resources in the future through solar energy conversion. In this study, mesoporous graphitic carbon nitride (g-C3N4) layers modified by detonation nanodiamond (DND) were synthesized by condensation from urea to obtain a robust and efficient hybrid (g-C3N4-DND) photocatalyst for the HER. Our characterizations revealed that no significant structural changes occurred in g-C3N4 during the synthesis of the g-C3N4-DND hybrid. Compared with pure g-C3N4, hydrogen production increased by almost 50% when using the hybrid photocatalyst due to the synergetic effect of the enhanced charge transfer, high surface area and low recombination rate of the photogenerated charge carriers.
