摘要
采用水热法制备不同铁掺杂比例下的钨酸铋复合光催化剂,通过SEM、UV-Vis和PL表征手段对材料的结构及其光学性能等进行了表征。以罗丹明B作为目标污染物,考查了Fe/Bi_(2)WO_(6)复合材料的降解能力。结果表明,掺杂量为11%时,复合光催化剂在光催化-芬顿协同作用下的降解能力最好,此外,对催化剂投加量、H_(2)O_(2)投加量、pH等反应条件进行优化。最后提出了光芬顿降解机理。
The photocatalytic materials of Bi_(2)WO_(6) with different iron doping ratios were prepared by hydrothermal method.The structure and optical properties of the materials were analyzed by SEM,UV Vis and PL characterization methods.The degradation ability of Fe/Bi_(2)WO_(6) was investigated with Rhodamine B as the target pollutant.The results showed that when the dosage was 11%,the degradation ability of the composite photocatalyst under the synergistic action of photo-Fenton was the best.Then the reaction conditions such as the dosage of catalyst,H2O2 and pHwere optimized.Finally,the photo-Fenton degradation mechanism was proposed.
