摘要

•Co@N-doped carbon was prepared by pyrolysis of ZIF-8@ZIF-67 to modify CdSe QDs.•The k of Cr(VI) reduction over 2%Co@C/CdSe is 33.9 times higher than that of CdSe.•The best H2 evolution rate of 2%Co@C/CdSe is 139 times larger than that of CdSe.•Enhanced charge separation and light absorption is responsible for high activity.
