Abstract
The present study describes the potential use of cadmium cobaltite nano-flower (CCNF) as photocatalyst for the removal of organic dye. The CCNF was prepared through facile, one-pot and costeffective hydrothermal approach. The designed CCNF was found to possess heterogeneous photocatalytic potential against the oxidative degradation of crystal violet dye taken as a model pollutant. The photocatalytic performance of CCNF was evaluated under visible light. The best photocatalytic performance was achieved under visible light with almost complete degradation (87.80%) exhibited within 2 hr of irradiation time. Furthermore, the degradation efficiency of the prepared CCNF was determined in the presence and absence of quenchers and under different pH conditions. The intermediates and final products were investigated by FTIR analysis. The radical trapping studies show that holes (h+), superoxide radicals (•O2ˉ) and hydroxyl radicals (•OH) were identified as the main active species in the reaction. The plausible catalytic mechanism and process were proposed. Finally, this technique can be effortlessly scaled-up for the removal of various polycyclic organic wastes that may be of potential industrial and environmental interests.
