碱处理改性对 TiO2光催化及吸附性能的影响
Effects of Alkali Treatment for Modification on Photocatalytic and Adsorotion Performance of TiO2
摘要
Abstract
The methods and technology of surface modification of the TiO2 by using NaOH as the modification agent were analyzed.The capacity of adsorption and the effect of degradation on the organic pollutants were improved by changing the surface morphology and the chemical activities of the nano-TiO2.After modification, the specific surface area increased from 28.07 m2/g to 79.83 m2/g and the surface of the sample become larger more rough.While the average pore size of the nano-TiOz decreased from 1Onm to 4.135 nm, and its iodine adsorption values increased from 35.6 mg/g to 102.79 mg/g.The iodine adsorption loop of the TiO2 after modification showed that it was belong to the H1 type of IUPAC adsorption loop.The catalysising degradation rate of Dichloromethane (DCM) by the modification nano-TiO2 was increased several times than that of Dich]oromethane(DCM) by the untreated.关键词
