“…The distinctive combination of multiferroic behavior, favorable band gap, and photovoltaic effect endows BiFeO 3 with remarkable potential for advanced photocatalytic systems. Extensive research efforts dedicated to exploring and harnessing the diverse functionalities of BiFeO 3 -based materials for efficient and sustainable photocatalysis [ [39] , [40] , [41] , [42] , [43] , [44] ]. In 2018, a suite of cobalt ferrite nanostructures doped with bismuth (CoBixFe 2-x O 4 , x = 0.02, 0.04, 0.06, 0.08, 0.1) were synthesized via the sol-gel approach to investigate their catalytic efficiency in the degradation of harmful dyes under both visible light irradiation and non-irradiated conditions [ 45 , 46 ].…”
