摘      要：A series of bimetallic metal-organic frameworks (MOFs) photocatalysts had been successfully synthesized by doping nickel (Ni) into zeolitic imidazolate framework-8 (ZIF-8) for enhanced photodegradation of methylene blue (MB). Optical characterization revealed that the Ni-ZIF-8 composites possessed a narrower bandgap and lower recombination rate of charge carriers than pristine ZIF-8. The Ni(20)-ZIF-8 composite showed the highest MB photodegradation efficiency of up to 93.22% in 150 min. The scavenger test clearly proved that h+ and •OH were the main active species in the degradation of MB. The synthesized bimetallic Ni(20)-ZIF-8 composite is a promising photocatalyst for removal of MB in aquatic environments. © 2024, The Authors. All rights reserved.
