| 中文摘要 | 采用两步法进行纳米铂在碳纳米管表面的原位担载。首先利用柠檬酸(CA)对苯胺(ANI)自组装作用,制备PANI/CNT复合载体;进而比较了柠檬酸络合及未络合氯铂酸前驱体两种方式,通过原位还原铂,制备纳米铂-聚苯胺-碳纳米管(Pt-PANI/CNT)复合材料。结果表明,CA在初期利于PANI完整包覆CNT,且CA络合氯铂酸方式在后期利于纳米铂均匀可控担载,从而所得Pt-PANI/CNT材料表现出高电化学活性面积、甲醇的稳定电催化活性。对拓展复合纳米结构及性能提出了可行路线,利于未来探索。; This paper adopted two-step synthesis to in-situ load nano-Pt on carbon nanotube surface.Initially,we used the self-assembly effect from citric acid(CA)on aniline to prepare PANI/CNT composite support.Then,we compared two approaches as the CA coordination with H2PtCl6 precursor and without coordination,further in situ reduction for nano-Pt to achieve Pt-PANI/CNT structures.Our results showed that CA helps complete PANI wrapping for CNT surface initially,and its coordination with H2PtCl6 precursor benefits the uniform distribution and size control for nano-Pt subsequently,thus its Pt-PANI/CNT structure exhibiting high electrochemical surface area and stable methanol electro-oxidation behaviors.In this regard,we provided feasible routines to extend composite structures and their properties,helping for future explorations. |
