Currently, two-dimensional/two-dimensional (2D/2D) van der Waals heterojunctions, as novel and excellent candidates for photocatalysts, have attracted significant attention because of their fundamentally improved interfacial charge separation/transfer and massive reactive centers. Herein, novel 2D/2D TaN-nanosheet/ReS-nanosheet van der Waals heterojunction photocatalysts are rationally designed through a method combining template-assisted and solution-adsorption processes. The resultant heterojunctions exhibit enhanced interfacial charge transfer, boosted light absorption and significantly increased reaction sites for hydrogen evolution. Correspondingly, they deliver a high photocatalytic hydrogen production activity of 615 μmol g h, which is ∼3 and ∼12 times greater than that of bare TaN nanosheets and ReS nanosheets, respectively, and superior to those in the most recent reports about photocatalytic water splitting on TaN material, implying their potential applications as advanced catalysts for hydrogen evolution.
目前，二维/二维（2D/2D）范德华异质结作为光催化剂的新型优秀候选材料，因其界面电荷分离/转移得到根本改善以及具有大量活性中心而备受关注。在此，通过模板辅助和溶液吸附相结合的方法合理设计了新型2D/2D TaN纳米片/ReS纳米片范德华异质结光催化剂。所得异质结表现出增强的界面电荷转移、增强的光吸收以及显著增加的析氢反应位点。相应地，它们具有615 μmol g⁻¹ h⁻¹的高光催化产氢活性，分别比裸TaN纳米片和ReS纳米片高约3倍和约12倍，并且优于最近关于TaN材料光催化水分解的报道中的活性，这意味着它们作为析氢先进催化剂的潜在应用。
