摘要:
为提高催化剂光催化降解煤矿瓦斯效率，运用溶胶-凝胶浸渍过程将具有优异吸附性能的活性炭颗粒引入催化剂，制备了新型复合催化剂Ga2O3/AC。采用XRD、SEM、N2吸附等方法对新型复合催化剂的结构形貌及比表面积进行理化表征，验证了复合催化剂制备方法的可行性。同时以真空紫外灯为光源，进行光催化氧化降解瓦斯的模拟实验，对比考察Ga2O3、活性炭颗粒及复合催化剂的光催化活性。结果表明，相比单一Ga2O3，复合催化剂光照时间为180 min后对甲烷的降解率提高了13%，达到100%去除率。
Abstract:
In order to improve the degradation efficiency of coal-mine gas by photocatalysis of catalyst, the particles of activated carbon (AC) with excellent adsorption performance were introduced into the catalyst by using the sol-gel dipping process, and a new composite catalyst Ga2O3/AC was prepared. The characterization of physicochemical properties were carried out on the structure, morphology and specific surface area of the new composite catalyst by using the X-ray diffraction (XRD), scanning electron microscopy (SEM), and N2 adsorption methods, then the feasibility of preparation method for the composite catalyst was validated. Meanwhile, the simulation experiments of gas degradation by photocatalytic oxidization were conducted by taking the vacuum ultraviolet lamp as light source, and the photocatalytic activities of Ga2O3, AC particles and composite catalyst were compared and investigated. The results showed that compared with pure Ga2O3, the degradation ratio of methane by the composite catalyst increased by 13%, reaching the 100% removal rate, after 180 minutes of illumination time.
