Preparation and Photocatalysis of g-C3N4/Zeolites Based on Photocatalytic Activity and Adsorption Support Ability
A g-C3N4/zeolites photocatalyst is designed so that give full play to the photocatalytic activity of g-C3N4 and adsorption support ability of zeolites. g-C3N4 and zeolites are chosen as a photocatalyst group thanks to
an excellent optical performance of g-C3N4 and an unique porous structure of zeolites as well as their common high stability. The best amount of g-C3N4 loaded on zeolites is determined. The optical performance of g-C3N4 and
photocatalytic property of g-C3N4/zeolites are characterized. The methylene blue decolouration rate of g-C3N4/zeolites (CNZ-2) reaches 92.4% under visible light irradiation at 120 min, which is greater than that of zeolites (89.6%) at 180 min. The
photocatalytic mechanism of g-C3N4 is discussed in detail. Additionally, this composite structure will offer an insight to solve the recycle and aggregation of photocatalysts in water.
