The conversion of solar energy into chemical energy through photocatalysis is an important field of interest in green energy generation and environmental improvement. Nevertheless, its effectiveness currently falls short of expectations, primarily due to the issue of charge recombination. To address this challenge, the piezo-photocatalytic effect has become an optimistic approach for enhancing photocatalytic processes. In this study, we have developed a series of CoFeO3/Ce-MOF nanocomposites by combining Cerium metal-organic frameworks with MOF-derived CoFeO3. To gauge their effectiveness, the CoFeO3/Ce-UiO-66, CoFeO3/Ce-MOF-808, and CoFeO3/Ce-MOF-801 heterostructures were assessed by employing multiple characterization methods including XRD, IR, FESEM, DRS, EDX, VSM, PL, EIS, Zeta, and BET. Generally, among the different nanocomposites studied, CoFeO3/Ce-MOF-801 achieved a remarkable result an outstanding 100% efficiency in reducing hexavalent chromium within just 30 minutes, and in ammonia generation, with a rate of 292.13 μmol g−1 h−1L-1. The results indicate that CoFeO3/Ce-MOFs have the potential to be an eco-friendly and affordable piezo-photocatalyst that can effectively tackle the challenges of sustainable ammonia production and the removal of harmful Cr(VI) contaminants from water. This recently developed catalyst demonstrates promising capabilities for a wide range of applications.
