摘　　要：多孔碳材料具有优秀的吸附、导电、催化、储氢性能,可作为载体用于制备多功能复合材料,具有广泛的应用前景。通过将多枝柽柳进行不同温度的碳化,制备不同形貌与结构的多孔碳材料,用Ag_(3)PO_(4)负载在多枝柽柳多孔碳材料上,考察对罗丹明B催化降解性能,通过SEM、FTIR、UV-Vis表征其结构与性能。结果表明,多孔碳材料在负载Ag_(3)PO_(4)后,孔隙平均直径约200 nm。紫外可见光谱测试表明,在700℃碳化的多孔碳材料负载磷酸银复合材料可有效降解罗丹明B染料,在90 min时脱色率达97.8%。为光催化剂的有效负载以及生物多孔碳复合光催化材料的探究提供了新思路。Porous carbon materials have excellent adsorption,conductive,catalytic and hydrogen storage properties,which can be used as a carrier to prepare multifunctional composite materials,and have a wide range of application prospects.Porous carbon materials with different morphologies and structures were prepared by carbonizing Tamarix ramosissima at different temperatures.The catalytic degradation of Rhodamine B by Tamarix ramosissima was investigated by Ag_(3)PO_(4)loading.The structure and properties were characterized by SEM,FTIR and UV-Vis.The results showed that the porous carbon material with Ag_(3)PO_(4)had 200 nm uniform pores on its surface.In the UV-V is spectrum,the porous carbon material loaded silver phosphate composite obtained by carbonization at 700℃ was able to effectively degrade rhodamine B dye with a decolorization rate of 97.8% at 90 min.A new idea for the research of photocatalyst payload and new photocatalytic materials was provided.
