Nano flake Ag3PO4 enhanced photocatalytic activity of bisphenol A under visible light irradiation
Source abstract
Abstract
Abstract Bisphenol A (BPA) persistently exist in environment, bioaccumulative and toxic to wild life. The nano flake Ag3PO4 photocatalyst and its photocatalytic performance on BPA under visible light irradiation was investigated. The degradation rate constant of BPA by the nano flake Ag3PO4–2 was 9.71 times of that by the cube Ag3PO4. The radical of h+ and •O2− principally contributed in the BPA degradation. The powder XRD and TEM showed that the nano flake Ag3PO4–2 exposed (111) crystal surface, and displayed a flake structure with a length of about of 4–6 μm and wide of 0.05–0.1 μm. In addition, the band gap energy was 2.39 eV. The Photoluminescence (PL) intensity of the nano flake Ag3PO4–2 was lower than the cube Ag3PO4. The high photocatalyst activity might be attributed to extended light absorption and obviously accelerated carrier transfer, which are accounted by the increasing (111) crystal number and catalytic active sites.
