摘要: Abstract Mesoporous graphitic carbon nitride (mg-C3N4) has been prepared by the in situ formed silica from tetraethylorthosilicate (TEOS) as a mesoporous template. The resultant mg-C3N4 possessed large surface area (152 m2 g− 1), and enhanced photodegradation performance for Rhodamine B pollutant when energized with visible light. Moreover, also exhibited good stability after three recycles. significant enhancement activity over catalyst could be ascribed to area, high adsorption ability dye separation efficiency of photogenerated electron-hole pairs. simple strategy fabrication may facilitate its wide applications various fields.
