| 摘 要：多孔碳材料具有優(yōu)秀的吸附、導電、催化、儲氫性能，可作為載體用于制備多功能復合材料，具有廣泛的應用前景。通過(guò)將多枝檉柳進(jìn)行不同溫度的碳化，制備不同形貌與結構的多孔碳材料，用Ag3PO4負載在多枝檉柳多孔碳材料上，考察對羅丹明B催化降解性能，通過(guò)SEM、FTIR、UV-Vis表征其結構與性能。結果表明，多孔碳材料在負載Ag3PO4后，孔隙平均直徑約200 nm。紫外可見(jiàn)光譜測試表明，在700 ℃碳化的多孔碳材料負載磷酸銀復合材料可有效降解羅丹明B染料，在90 min時(shí)脫色率達97.8%。為光催化劑的有效負載以及生物多孔碳復合光催化材料的探究提供了新思路。 |

| Abstract：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 Ag3PO4 loading. The structure and properties were characterized by SEM, FTIR and UV-Vis. The results showed that the porous carbon material with Ag3PO4 had 200 nm uniform pores on its surface. In the UV-Vis 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. |
