丙醇和丁醇异构体在钯镍电极上的电催化氧化
, PP. 1274-1280
Keywords: pdni电极,丙醇氧化,丁醇氧化,&beta,-环糊精,muliken净电荷
Abstract:
？β环糊精(β-cd)具有特殊的空腔结构,将β-cd修饰的多壁碳纳米管(mwcnt)涂在钛基底上,采用电沉积的方法在修饰的钛基底上沉积纳米pdni催化剂。sem结果表明,pdni纳米颗粒在β-cd/mwcnt修饰的钛片上有较好的分散度,粒径为90~130nm。在碱性溶液中,测试了pdni-β-cd/mwcnt/ti电极分别对丙醇和丁醇不同异构体氧化的电催化活性;通过计算与-oh相连的碳原子上的muliken净电荷,分析不同异构体的氧化机理。结果表明,不同异构体的氧化活性不同,pdni-β-cd/mwcnt/ti电极对正丙醇和正丁醇的氧化活性明显高于其异构体,-oh所在碳原子上的muliken净电荷越小,醇类分子越容易被氧化。
