提出了一种简单的光沉积方法用于合成新型Ag/g - C₃N₄复合纳米片（AGCNs），其中直径为5到20纳米的Ag纳米粒子均匀地负载在g - C₃N₄纳米片上，形成了一种异质结构。与纯g - C₃N₄纳米片相比，在AGCNs中观察到在可见光范围内有更强的吸收以及光生载流子更低的复合概率。通过在可见光照射下对罗丹明B（RhB）进行光催化氧化分解来评估所制备样品的光催化活性。实验结果表明，AGCNs（8 wt%）表现出最高的光催化活性，其相应的降解速率是纯g - C₃N₄纳米片的7倍。（C）2015爱思唯尔有限公司。保留所有权利。
A simple photodeposition method was presented for synthesis of novel Ag/g-C3N4 composite nanosheets (AGCNs) where Ag nanoparticles with diameters of 5 to 20 nm were evenly loaded onto g-C3N4 nanosheets forming a heterogeneous structure. Compared to the pure g-C3N4 nanosheets, more intensive absorption within the visible light range and lower recombination probability of photogenerated charge carriers were observed in AGCNs. Photocatalytic activities of the as-prepared samples were evaluated by the photocatalytic oxidation decomposition of Rhodamine B (RhB) under visible light irradiation. The experimental results showed that AGCNs (8 wt%) exhibited the highest photocatalytic activity and the corresponding degradation rate was 7 times as much as that of pure g-C3N4 nanosheets.
