氢气还原法制备Bi/Bi2WO6及其光催化降解性能OA北大核心CHSSCDCSTPCD
Preparation of Bi/Bi2WO6 by H2 reduction method and its photocatalytic degradation performance
通过H2还原法制备Bi/Bi2WO6以减少杂质的引入,并探讨最佳H2还原条件、Bi/Bi2WO6为光催化剂的降解机制和稳定性.结果表明,200 ℃下还原30 min制得的Bi/Bi2WO6具有最好的光催化活性,光照240 min后,降解率可达到69.7％.Bi/Bi2WO6光催化活性提高的原因有:表面等离子共振(SPR)效应提高了对450～800 nm波长光的吸收;BWO与金属Bi接触产生的内置电场促进了光生电子-空穴对的分离;氧空位的存在降低了…查看全部>>
Bi/Bi2WO6 was prepared by H2 reduction method to reduce the introduction of impurities.The optimal H2 reduction conditions and the degradation mechanism and stability of Bi/Bi2WO6 as a photocatalyst were discussed.The results showed that Bi/Bi2WO6,prepared by reduction at 200 ℃ for 30 minutes,had the best photocatalytic properties,and its degradation rate could reach 69.7％after 240 minutes of illumination.The reasons for the enhanced photocatalytic activity …查看全部>>
