| Abstract: | "A photocatalyst with a high separation efficiency of carriers is crucial for the photocatalytic efficient decomposition of volatile organic compounds (VOCs). In this work, a new iodine-deficient BiO(1.2) I(0.6) /Bi(2) O(3) photocatalyst was developed through a solvothermal approach coupled with thermal decomposition. The 2 wt % BiO(1.2) I(0.6) /Bi(2) O(3) sample demonstrated optimal photocatalytic activity for the degradation of toluene, achieving a 55.1 % mineralization ratio under 8 h of irradiation, which was 14.9 and 2.1 times higher than those of BiO(1.2) I(0.6) and Bi(2) O(3) , respectively. Compared with BiO(1.2) I(0.6) and Bi(2) O(3) , 2 wt % BiO(1.2) I(0.6) /Bi(2) O(3) exhibited the weakest fluorescence band, highest photocurrent density, and lowest impedance; thus suggesting that Bi(2) O(3) compounded by 2 wt % BiO(1.2) I(0.6) distinctly promoted the separation efficiency of carriers. The hydroxyl radical ((.) OH) was the main active species, apart from holes, for the photocatalytic degradation of toluene" |
