Water pollution by organic dyes, such as methylene blue (MB), has become an increasingly important issue. g-C3N4/SiO2 aerogel composites exhibit potential for removing dyes but are still limited their small specific surface area and low photochemical efficiency. In this study, we propose approach preparing combining sol-gel calcination processes to optimize the materials’ adsorption photocatalytic synergistic effects structural design. composites, layered g-C3N4 nanosheets grew uniformly on inside SiO2 three-dimensional network structure. Among them, 20-g-C3N4/SiO2 showed highest MB degradation efficiency, with a of 151.5 m2/g pore diameter 11 nm. Under visible light, it achieved 92% at dosage 0.2 g/l 50 mg/l initial concentration, which was 6.1 times rate 3.4 aerogel. Moreover, material exhibited excellent cyclic stability degraded 85% after three cycles. The effectively adsorbed focused surfaces because superior capacity facilitated in situ under light. This process efficient high concentrations MB, indicating application value removal from water.
