摘要
以聚乙烯亚胺(PEI),N-羟基琥珀酰亚胺(NHS)和溴丙酸(BPA)为原料,按不同质量比r[m(Fe-NHS)∶m(PEI-CO2H)]合成了三种基于[Fe Fe]-氢化酶模型化合物的聚合材料Mr(r=5.5,9.0,12.0),其结构和性能经IR和CV表征。用循环伏安法考察了醋酸存在下,M5.5,M9.0和M12.0的催化制氢性能。结果表明:M12.0的催化性能最好,其催化电流为2.0μA。
Three polymeric materials[Mr（ r = 5. 5,9. 0,12. 0） ],based on [Fe Fe]-hydrogenase model complex,were synthesized according to different mass ratio（ r） [m（ Fe-NHS） ∶ m（ PEICO2H） ],using PEI,NHS and BPA as materials. The structures and performance were characterized by IR and CV. The catalytic activities of M^5. 5,M^9. 0and M^12. 0in Ac OH were investigated by cyclic voltammetry method. The results showed that M12. 0exhibited better catalytic activities. The catalytic current of M12. 0was 2. 0 μA.
