Noble metal-free MoS₂/g-C₃N₄ photocatalysts have been synthetized by one step thermal treatment of thiourea and sodium molybdate, which has intimate contact interfaces between g-C₃N₄ and MoS₂. The hydrogen generation rate of MoS₂/g-C₃N₄ photocatalyst is 280 µmol·g⁻¹·h⁻¹, 40 times as that of pristine g-C₃N₄. The enhanced activity is attributed to the in-situ generated intimate interfaces, which leads to enhanced absorption of visible light and higher efficiency of charges separation.

MoS2/g-C3N4 光催化剂的简易一步合成与增强的可见光光催化制氢

通过硫脲和钼酸钠一步热处理合成了不含贵金属的MoS ₂ /gC ₃ N ₄光催化剂，其在gC ₃ N ₄和MoS ₂之间具有紧密的接触界面。MoS ₂ /gC ₃ N ₄光催化剂的产氢率为280 μmol·g ^-1 ·h ^-1，是原始gC ₃ N _{4 的}40倍。增强的活性归因于原位生成的紧密界面，这导致可见光吸收增强和电荷分离效率更高。
