研究了含有细胞色素氧化酶(CcO)氧还原位功能类似物的聚丙烯酸(PAA)和聚乙烯基吡啶(PVP)聚合物在溶液和电极表面对O2的催化还原活性。观察到卟啉微环境对催化剂的选择性和转化率有显著影响。
Activity toward catalytic O2reduction by polyacrylic acid (PAA) and polyvinylpyridine (PVP) polymers containing functional analogues of the O2-reducing site of cytochromecoxidase (CcO) has been studied in solution and on the electrode surface. Pronounced effects of the porphyrin microenvironment on the selectivity and turnover frequency of the catalysts were observed.
