One-pot approach Decompose ammonia and nitrogen gas from an organic pollutantammonia mixed solution [223] Titanium tetraisopropoxide (TTIP) and carbon nanostructures (MWCNT or Fullerene (C60)) were hydrothermally processed to make magnetic bronze F-TiO2/carbon nanostructure NCs. MG was utilized as a contaminant to test magnetic catalyst photocatalysis. The study found that the F-TiO2(B)/ MWCNT@NiFe2O4 and F-TiO2(B)/Fullerene@NiFe2O4 NCs photo catalytically degrade MG dye at 93% and 98% after 120 mins of visible irradiation. F-TiO2(B)/carbon nanostructure@NiFe2O4 NCs degrade well and may be reused four times without losing efficacy. Ghosh, B.K. et al. developed a non-hydrothermal synthesis for producing TiO2/CoFe2O4/rGO NCs, which are effective catalysts for breaking down hazardous organic dyes. Kodasma, et al. conducted a study on the photocatalytic efficiency of CuFe2O4XGO, which is a hybrid catalyst consisting of CuFe2O4 and GO, to remove dyes. The findings indicated that catalysts with varying weight ratios of GO have great potential as practical options for environmentally friendly wastewater treatment methods. Liu, Shou-Qing, and colleagues used a single-location method to synthesize catalysts of ZnFe2O4 and ZnFe2O4 with rGO (ZnFe2O4/rGO). The researchers found that the interaction between Zn cations on ZnFe2O4 and ammonia in solution led to the selective breakdown of ammonia and nitrogen gas from a mixture of organic contaminant and ammonia solution using the ZnFe2O4/rGO catalyst. Under visible light exposure, the surface photovoltage spectra indicated that the photogenerated holes migrated towards the surface of ZnFe2O4 particles, resulting in the removal of ammonia adsorbed on the catalyst surface.
