摘要
聚合物半导体石墨相氮化碳(g-C_(3)N_(4))具有独特的电子结构和化学性质,是一种新型的非金属功能性材料,在利用太阳能转化清洁能源和化学合成领域受到广泛关注。但由于其本身结构的限制性纯g-C_(3)N_(4)光催化效果并不尽人意。而稀土离子掺杂是调节带隙,降低大的层间电阻并增强g-C_(3)N_(4)的光催化活性合适且有效的技术。本文通过介绍稀土的独特性质,总结了近几年稀土离子掺杂g-C_(3)N_(4)的研究工作,并对该领域的研究方向进行了展望与探讨。
Polymer semiconductor graphitic carbon nitride(g-C_(3)N_(4)),a new-type metal-free functional material, possesses distinct electronic structure and chemical property, and has attracted a wide spread attention in clean energy conversation and chemical synthesis using solar power.However, due to the limitation of its structure, the photocatalytic effect of pure g-C_(3)N_(4) is not satisfactory. Rare earth ions doping is a suitable and effective technique to modulate band gap, reduce large interlayer resistance and to enhance photocatalytic activity of g-C_(3)N_(4). By introducing the unique properties of rare earth elements, this paper summarizes the research work of rare earth doped g-C_(3)N_(4) in recent years, and prospects and discusses the research direction in this field.
