| 摘 要： | 石墨相氮化碳(g-C_3N_4)具有稳定的光学性质、化学性质等优点,但也存在一些缺点。因此,为了更好的利用石墨相氮化碳,改变石墨相氮化碳应用领域的探究是非常重要的。利用循环伏安法在过氧化氢溶液中对不同的石墨相氮化碳薄膜电极进行了氧化还原反应测试,进而研究了电极上发生的电化学反应的可逆性及其动力学特征,从而判断电极电催化活性的高低。研究表明,该修饰电极对过氧化氢具有电催化还原作用,铂基石墨相氮化碳的催化效果比纯的电催化优越。

| Abstract: | graphite nitride carbon(g-C_3N_4) has the advantages of stable optical properties and chemical properties, but it also has some disadvantages. Therefore, in order to make better use of the graphite phase carbon nitride, it is very important to change the application area of the graphite phase carbon nitride. In this paper the hydrogen peroxide solution of different graphite carbon nitride thin film electrode by redox reaction test by cyclic voltammetry, reversibility and kinetic characteristics of the electrochemical reaction occurs on the electrode, thereby judging electrocatalytic activity level. The results show that the modified electrode has electrocatalytic reduction effect on hydrogen peroxide, and the catalytic effect of platinum based graphite nitride carbon is superior to that of pure electrocatalytic carbon. |
