Abstract

In this study, the defective ZnS yolk shell nanospheres are synthesized through a facile solvothermal method followed by a calcination process to introduce sulfur vacancies. The defective ZnS yolk-shell nanospheres show excellent sonocatalytic performance for hydrogen production, as compared to ZnS nanospheres and other commonly used sonocatalysts. The enhanced sonocatalytic activity is attributed to the synergistic effect of the yolk-shell structure and the introduction of sulfur vacancies. Furthermore, the defective ZnS yolk-shell nanospheres demonstrate good stability for sonocatalytic hydrogen production.

具有硫空位的缺陷 ZnS 卵黄壳纳米球用于高效声催化制取 H2

本研究采用简便的溶热法合成了有缺陷的 ZnS 卵黄壳纳米球，然后通过煅烧过程引入硫空位。与 ZnS 纳米球和其他常用的声催化剂相比，有缺陷的 ZnS 卵黄壳纳米球在制氢方面表现出优异的声催化性能。增强的声催化活性归功于卵壳结构和硫空位的引入所产生的协同效应。此外，有缺陷的 ZnS 卵黄壳纳米球在声催化制氢方面表现出良好的稳定性。
