TDOS计算结果表明(Figure 4a),当氧化层出现时,杂化晶体(MoS2/MoO3)可由原来半导体(MoS2和MoO3)性质转换为金属性质,且O-MoS2@Pt在费米能级附近展现出最强的载流子密度,这表明Pt修饰富含空位的纳米反应器具有最优的导电性,使得OER过程中的电荷转移变得更加容易。 此外,具有硫空位和Pt修饰的原子周围发生明显的局域电...
Then, Had at the Pt and interface, and MoO3 sites reacted with H2O and HO to form H2 or H2O molecules, thereby boosting the HER/HOR activity. This work may provide valuable information for the development of hydrogen-spillover-based electrocatalysts for use in various renewable energy devices...
考虑到OER过程中的原位氧化层(MoO3)是真正的催化活性位点,利用CASTEP构建系列MoS2/MoO3晶体模型,采用第一性原理研究引入硫空位和Pt修饰引起的电子结构及热力学过程变化情况。TDOS计算结果表明(Figure 4a),当氧化层出现时,杂化晶体(MoS2/MoO3)...

Influence of support material on the catalyst systems Pt/SiO2 and WO3-and MoO3/SiO2. This article systematically reviews SiO2 carriers from the viewpoint of texture, structure, and surface chemistry, paying special attention to the properties of acid-modified silica gels and porous glasses. The ef...
Pt-based nanocatalysts offer excellent prospects for various industries. However, the low loading of Pt with excellent performance for efficient and stable nanocatalysts still presents a considerable challenge. In this study, nanocatalysts with ultralow Pt content, excellent performance, and carbon black ...
