observed in BiVO4 after Ni-B co-doping. When the optimal mass fraction of Ni is 0.30%, the degradation rate of MO in 50 min is 95% for 0.3Ni-B-BiVO4 sample which also can effectively degrade methyl blue (MB), acid orange (AOII) II and rhodamine B (RhB). The enhanced photocatalytic activity is attributed to the synergistic effects of B and Ni doping. Key words: co-doping; Ni doping; BiVO4......

co-doped ZnO nanoparticle photocatalyst due to the Nb/N co-doping effect.It demonstrated a largely enhanced photocatalytic performance in the disinfection of Escherichia coli bacteria under visible light illumination, which could be attributed to the passivated co-doping of NbN to suppress the photogenerated charge carrier recombination on dopants. This robust approach for passivated p-n co-doping......
