| 摘 要： | 合成了呋喃甲醛改性壳聚糖(FCS).将其与一定pH值的含Co2 、Cu2 硝酸铵溶液反应,制得呋喃甲醛改性壳聚糖金属钴、铜的螯合物(CoFCS、CuFCS),采用红外光谱法(IR)对FCS、CoFCS、CuFCS进行了表征.使CoFCS、CuFCS与碳基体混合,在氩气保护一定温度下热处理后,制成空气电极,通过测试极化曲线和放电曲线,研究了它的电催化性能.结果表明,CoFCS/C和CuFCS/C具有良好的氧气还原电催化性能,且CoFCS/C优于CuFCS/C.

| Abstract: | Furfural modified chitosan (FCS) was synthesized according to the literature, and the chelates were obtained by reacting FCS with solution containing Co2 and Cu2 at certain pH value and their structure were characterized by IR. The electrodes were made by mixture of CoFCS, CuFCS with active carbon after heat treatment in Ar. Their electrocatalysis properties by testing the polarisation and discharge curves were investigated. The results show that both CoFCS/C and CuFCS/C have good electrocatalysis properties and the electrocatalysis properties of CoFCS/C are better than that of CuFCS/C. |
