Layered g-C₃N₄ was obtained through secondary calcination, and the MoS₂–Ag/g-C₃N₄ catalyst was prepared via hydrothermal and light deposition methods. XRD, SEM and TEM results proved that the MoS₂–Ag/g-C₃N₄ sandwich biscuit structure was successfully obtained, and the sharper diffraction peak of MoS₂–Ag/g-C₃N₄ than g-C₃N₄ or MoS₂ is attributed to the synergistic crystallinity effect. SPR effect of Ag increases the electron transport time, which effectively prolonging the survival time of electron–hole pairs. Compared the degradation performance of 10mg/L rhodamine B (RhB) with different ratios of materials, 10wt.% MoS₂–Ag/g-C₃N₄ has the highest degradation property. The degradation rate remains at 87.2% under the best condition after four cycles proved that the MoS₂–Ag/g-C₃N₄ composite possesses good stability.

降解罗丹明 B 的 MoS2-Ag/g-C3N4 复合材料的制备

通过二次煅烧获得层状gC ₃ N _{4 ，并通过水热和光沉积法制备MoS 2} -Ag/gC ₃ N ₄催化剂。XRD、SEM和TEM结果证明，成功获得了MoS ₂ –Ag/gC ₃ N ₄夹心饼干结构，MoS ₂ –Ag/gC ₃ N ₄的衍射峰比gC ₃ N ₄或MoS _{2更尖锐。}归因于协同结晶效应。Ag的SPR效应增加了电子传输时间，有效延长了电子-空穴对的存活时间。比较10的降解性能mg/L 罗丹明 B (RhB) 不同材料配比，10wt.% MoS ₂ –Ag/gC ₃ N ₄具有最高的降解性能。四次循环后的最佳降解率仍保持在87.2%，证明MoS ₂ -Ag/gC ₃ N ₄复合材料具有良好的稳定性。
