In this paper, Ag nanoparticles (Ag NPs) were loaded on pure g-C₃N₄ (CN) via two different methods of direct heating and indirect heating to form g-C₃N₄/Ag-DX and g-C₃N₄/Ag-IDX photocatalysts, respectively. Using methylene blue as the degradation dye, the photocatalytic performance of g-C₃N₄/Ag-DX and g-C₃N₄/Ag-IDX was studied through visible light photocatalysis experiments. The results demonstrated that the photocatalytic performance of g-C₃N₄/Ag-DX and g-C₃N₄/Ag-IDX both increases with the increase in content of Ag nanoparticles. It is obvious that g-C₃N₄/Ag-ID8 has the optimal photocatalytic activity. Meanwhile, the g-C₃N₄/Ag-ID8 has excellent stability and can be reused in photocatalysis experiments.

本文通过直接加热和间接加热两种不同的方法将Ag纳米颗粒（Ag NPs）负载在纯gC ₃ N ₄（CN）上，形成gC ₃ N ₄ / Ag-DX和gC ₃ N ₄ / Ag-IDX光催化剂。以亚甲基蓝为降解染料，通过可见光光催化实验研究了gC ₃ N ₄ / Ag-DX和gC ₃ N ₄ / Ag-IDX的光催化性能。结果表明，gC ₃ N ₄ / Ag-DX和gC ₃ N ₄的光催化性能。/ Ag-IDX均随Ag纳米颗粒含量的增加而增加。显然，gC ₃ N ₄ / Ag-ID8具有最佳的光催化活性。同时，gC ₃ N ₄ / Ag-ID8具有极好的稳定性，可以在光催化实验中重复使用。
