    The extensive use of photocatalysis to address environmental concerns, energy production, and organic transformations has attracted attention in recent decades. The SnO/CSO photocatalytic materials were fabricated through a single-step hydrothermal method and comprehensively characterized using a muti-technique approach to demonstrate the physicochemical, morphological, and electronic features. According to the photocatalytic experiments, the SnO/CSO could remove >96% of acid blue 92 (AB92) azo dye under optimum conditions , with rate constant 2.37 x 10(-2) min(-1). Furthermore, the photocatalyst significantly outperformed commercial TiO2 (P25), in reducing CO2 to CO and CH4 with a production rate of 10.8 and 1.18 mu mol.g(-1).h(-1), respectively, under visible light irradiation. The successful direct alkylation of amines to valuable organic compounds within 10 min of the reaction time with a conversion selectivity of >90% was another capability of the materials, making it a good candidate for pharmaceutical synthesis purposes.
