2-吡咯甲醛改性壳聚糖钴螯合物的电催化性能
The electrocatalytic performance of 2-pyrrolyl-formaldehyde modified chitosan cobalt chelates
【摘要】 合成了2-吡咯甲醛改性壳聚糖(PRCS)与2-吡咯甲醛改性壳聚糖钴螯合物(CoPRCS),并对产物进行了IR表征。在氩气保护下,于650℃和900℃下分别对CoPRCS进行热处理,通过极化曲线和放电曲线的测试,研究了它们的电催化性能。结果表明:CoPRCS具有氧还原电催化活性。
【Abstract】 2-pyrrolyl-formaldehyde modified chitosan(PRCS) and 2-pyrrolyl-formaldehyde modified chitosan cobalt chelates(CoPRCS) were synthesized.The products were characterized by IR.The CoPRCS was heat-treated in Ar at 650 ℃ and(900 ℃.)The electrocatalytic performance of CoPRCS was evaluated by the polarization and discharge curves.The results showed that the CoPRCS had electrocatalytic performance of oxygen reduction.
