A colorimetric detection strategy and micromotor-assisted photo-Fenton like degradation for hydroquinone based on the peroxidase-like activity of Co 3 O 4 –CeO 2 nanocages
Micromotors have great potential in environmental monitoring and treatment. Herein, ZIF-67 derived Co 3 O 4 –CeO 2 micromotors with a porous nanocage structure were synthesized by the ingenious combination of template scarification and calcination methods. Co 3 O 4 inherited the typical porous struc...
