一维/二维MoO2-ZnIn2S4异质结的构筑与光催化活性研究OA
Research on construction and photocatalytic activity of 1D/2D MoO2-ZnIn2S4 heterojunction
直接利用太阳能实现光催化还原制取氢气,是解决能源危机的有效策略之一.过渡金属硫化物具有优异的可见光光谱利用率和适宜的能级能带结构,使其成为研究热点,然而,过高的充电速率极大地制约了它的应用.因此,构建合适的肖特基异质结可以有效提高其光催化性能.研究将ZnIn2S4纳米片均匀的负载在MoO2纳米棒上构成一维/二维MoO2-ZnIn2S4肖特基异质结,诱导了有效的电荷分离和转移,相较于单一的ZnIn2S4材料产氢速度大幅提高.
One of the effective strategies to solve the energy crisis is to produce hydrogen by photocata-lytic reduction directly using solar energy.Due to their excellent utilization rate of visible light spectrum and suitable energy level band structure,transition metal sulfides have become a research hotspot.Howev-er,the excessively high charging rate greatly restricts its application.Therefore,constructing suitable Schottky heterojunction can effectively improve its photocatalytic performance.In this study,we uniformly loaded ZnIn2S4 nanosheets onto MoO2 nanorods to form 1D/2D MoO2-ZnIn2S4 Schottky heterojunction,which induced effective charge separation and transfer,significantly increasing hydrogen production rate compared to a single ZnIn2S4 material.
