Synthesis of Noble Metal/Graphene and the Electrocatalytic Research on Tetracycline Hydrochloride

以石墨烯、4-(2-吡啶偶氮)-间二苯酚和氯钯酸为前驱体,通过电化学沉积法制备了钯/4-(2-吡啶偶氮)-间二苯酚/石墨烯复合电极,并利用循环伏安法在硫酸溶液中对该电极进行表征。随后将电极应用到对盐酸四环素的电催化中,分析了4-(2-吡啶偶氮)-间二苯酚/石墨烯电极、4-(2-吡啶偶氮)-间二苯酚/石墨烯聚合电极及钯/4-(2-吡啶偶氮)-间二苯酚/石墨烯聚合电极对盐酸四环素的电催化效果,同时研究了扫描速度和盐酸四环素浓度对电催化效果的影响。

Based on graphene and palladium chloride acid as precursor, we prepared palladium/poly4-(2-pyridylao)-resorcinol/graphene composite electrode by the method of electrochemical deposition, and characterized the electrode using cyclic voltammetry in sulfuric acid solution. Then we applied the electrode to tetracycline hydrochloride in electrocatalysis, analyzing the electrocatalytic effect of 4-(2-pyridylazo)-resorcinol/graphene, poly4-(2-pyridylazo)-resorcinol/graphene and palladium/poly4-(2-pyridylazo)-resorcinol/graphene electrode to tetracycline hydrochloride, while studying the effect of scanning rate and the concentration of tetracycline hydrochloride to catalytic effect.
