Ginkgo leaves extract-assisted synthesis of ZnO/CuO nanocrystals for efficient UV-induced photodegradation of organic dyes and antibacterial activity

Biogenic nanocrystals (NCs) were synthesized from Ginkgo biloba leaf extract (GLE) and applied as photocatalytic and antibacterial agents. XRD patterns revealed the formation of ZnO/CuO NCs with a crystalline quality and intra-granular coupling, and HRTEM images showed the globular morphology indicating a porous nature. The lower PL intensity of ZnO/CuO NCs specified the slower recombination rate of electrons and holes for enhanced...
