摘要:

通过一锅法合成了壳聚糖钴配合物(Cs-Co)催化剂. 电感耦合等离子体质谱与X光电子能谱测试结果表明, Cs-Co中Co元素的含量为1.1 mmol/g, Co为正二价. 在优化条件下, 18 mg Cs-Co催化剂的总催化产氢量达到12.7 mL(80 min), 催化产氢速率为30258 μmol·g -1·h -1. 通过研究Cs-Co的光催化并结合电化学方法, 提出了可能的光催化机理.

Abstract:

Chitosan-cobalt complex(Cs-Co) was synthesized by one-pot method. The content of Co in Cs-Co is 1.1 mmol/g and Co is positive bivalent. Under the optimized conditions, the total hydrogen production of 18 mg catalyst Cs-Co was 12.7 mL within 80 min, the hydrogen evolution rate was 30258 μmol·g -1·h -1. By studying the photocatalytic process of Cs-Co and combining with electrochemical method, a possible photocatalytic process and mechanism were proposed.

Key words: Chitosan, Cobalt oxime complex, One-pot method, Photocatalytic hydrogen evolution
