摘要
随着环境污染和能源短缺的加剧,无污染环境修复技术及清洁能源替代工程已成为一项重要而紧迫的任务。作为层状结构的过渡金属硫化物,二硫化钼带隙较窄,边缘具有高的反应活性,容易与其他物质形成复合结构,是近年来光催化环境修复及清洁能源领域的研究热点。本文详细介绍了半导体二硫化钼及其复合物的合成方法和光催化降解与产氢行为,重点阐述了二硫化钼及其复合物的具体复合方式、光催化降解污染物活性、光催化产氢活性以及具体的降解与产氢机理等方面的内容,并举例说明。二硫化钼及其复合物在光催化降解污染物和光催化产氢方面具有绿色、廉价、高效等优点,在环境修复及清洁能源领域具有巨大的潜力和应用发展前景。
With the gradual aggravation of environmental pollution and energy shortage,both developing technology on non-pollution environmental restoration and exploring project on alternative clean energy have recently become a very important and quite urgent task.As one of the transition metal sulfides with layered structures similar to graphene,molybdenum disulfide(MoS2) has become a research hotspot in the field of photocatalytic environmental remediation and clean energy(hydrogen generation) due to its narrow band gap,high reaction activity of the edges,and ease of forming a composite structure with other substances.This paper mainly introduces the synthesis methods,photocatalytic degradation and hydrogen generation behaviors of the MoS2 and its composites.Detailed methodologies for the synthesis of semiconductor MoS2 and its composites,photocatalytic degradation activity of pollutants,photocatalytic hydrogen generation activity and the corresponding mechanisms are emphasized and illustrated by a great many of the typical examples.MoS2 and its composites have displayed many advantages including environment friendliness,low cost and high efficiency in photocatalytic degradation of pollutants and photocatalytic hydrogen production.As the bright future materials,MoS2 and its composites have a broad application prospect in the field of environmental restoration and clean energy with the further development of its general mechanism.
