Metal–organic framework-derived porous carbon-mediated ZnO–nano-ZnO core–shell structure with excellent photocatalytic activity

ZnO–nano-ZnO@porous carbon (ZnO–nZnO@PC) was in situ fabricated through the Ostwald ripening mechanism and facile pyrolysis process, which demonstrated the performance of piezo-photocatalytic degradation efficiency of 99.4%.
