The cyclic voltammetry was used to study the catalysis properties of this porphyrin toward the dioxygen in different mediums including vitriol, ethanol and sodium carbonate solution. And the excellent catalysis toward dioxygen and H2O2 was proved. Further, the catalysis mechanisms were discussed. At last, it was suggested that the electrodes modified by CV scan was proposed to be a novel sensor for the dissolved oxygen or H2O2.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/zk/search.aspx?key=K%3d%5b%e9%87%91%e5%b1%9e%e5%8d%9f%e5%95%89%e8%86%9c%5d' title='金属卟啉膜'>金属卟啉膜</a> <a href='/subject/article.aspx?id=663011' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e4%bf%ae%e9%a5%b0%e7%94%b5%e6%9e%81%5d' title='修饰电极'>修饰电极</a> <a href='/zk/search.aspx?key=K%3d%5b%e7%a0%94%e5%88%b6%5d' title='研制'>研制</a> <a href='/subject/article.aspx?id=6783309' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e5%88%86%e5%ad%90%e6%b0%a7%5d' title='分子氧'>分子氧</a> <a href='/subject/article.aspx?id=2325897' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e5%8f%8c%e6%b0%a7%e6%b0%b4%5d' title='双氧水'>双氧水</a> <a href='/zk/search.aspx?key=K%3d%5b%e4%bc%a0%e6%84%9f%e5%99%a8%5d' title='传感器'>传感器</a> <a href='/subject/article.aspx?id=9231985' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e5%82%ac%e5%8c%96%5d' title='催化'>催化</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dTB43' title='TB43'>TB43</a>[<a href = '/domain/article.aspx?id=257' >一般工业技术</a>] <a href='/zk/search.aspx?key=C%3dO646.54' title='O646.54'>O646.54</a>[<a href = '/domain/article.aspx?id=410' >理学—物理化学</a>] </p>
