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.
