In this work, TiO2/graphene nanocomposite supported on clinoptilolite (CLP) nanoplate was prepared for the
first time by hydrothermal method and was used as efficient visible light photocatalyst for degradation of
nitenpyram insecticide. The results indicated that the photocatalytic degradation efficiency of TiO2/CLP/graphene
nanocomposite, containing 30 wt% CLP and 1 wt% graphene, was remarkably higher than that of pure
TiO2. This significantly improved photocatalytic performance could be mainly ascribed to the desirable advantages
of CLP and graphene, including microporous structure, increasing of the effective surface area,
enhancement of the visible light harvesting and improving of the charge carriers separation. Based on the radical
rapping experiments, the hydroxyl radicals were identified as main active species responsible for the photocatalytic
degradation of nitenpyram on the prepared photocatalyst. This study provides a new insight to fabricate
more effective zeolite and graphene-based nanocomposite photocatalysts for environmental remediation.
