Deskripsi
In this research, a novel spinel architecture of pure CdAl2O4 and Zn (0.025–0.075 M) doped CdAl2O4 nanoparticles were synthesized. The PL and ESR outcomes shows that the Zn doping played an effective role to prevent the e−-h+ pairs recombination in CdAl2O4 during photocatalysis. Zn (0.075 M)-CdAl2O4 provided the maximum photodegradation efficiencies for BB and BG with a removal efficiency of 91 and 96% in just 90 min as compared to other samples and remain stable after the fifth cycle. Such outcomes pave the approach for sustainable photocatalytic technologies to diminish the global influence of organic and inorganic dyes.
