As photocatalysts, heterojunction materials have attracted much attention because of their capacity to integrate the promising performance of the individual components. Here, a series of heterojunction materials composed of silver cyanamide (Ag2NCN) and graphitic carbon nitride (g-C3N4) have been fabricated using a facile grinding method. Upon photoexcitation, the heterojunction materials exhibited enhanced photocatalytic activity in the hydrogen evolution reaction (322.35 mol g(-1) h(-1)), 82.87 and 117.65 times higher than that of the pristine Ag2NCN and g-C3N4, respectively. The photoelectrochemistry results revealed that the loading of Ag2NCN onto g-C3N4 could be favorable to the photogenerated charge separation and transfer in the heterojuction system. In addition, the spent heterojuction retained a better photocatalytic activity after 30 hours recycling. Furthermore, the excellent synergetic effect between Ag2NCN and g-C3N4 could achieve the effectively promoted separation of photogenerated electron-hole pairs, thus leading to the enhancement of photocatalytic performance under simulated sunlight illumination. This work could provide a general strategy to fabricate Ag-based materials on g-C3N4 photocatalysts with superior H-2 evolution performance.
