摘要:
为制备具有较低铂（ Pt ）负载量的碳铂催化剂并提高其电催化析氢（ HER ）性能，采用一种简单的硬模板法制备了铂负载介孔碳球催化剂。通过调控添加试剂的间隔时间 t（t =2，8，16，32 min）制备得到具有不同核壳结构的介孔二氧化硅微球（SiO2 t ）；然后以其为模板，以盐酸多巴胺为碳前驱体，制成具有不同形貌结构的铂负载介孔碳球催化剂（Pt/C t ）。利用SEM、TEM和BET表征制备所得Pt/C t 微球的形貌和结构，通过电化学测试分析Pt/C  t 微球的电催化析氢性能。结果表明：Pt/C 2和Pt/C 8微球表面具有较好的放射状介孔，而Pt/C 16和Pt/C32微球形成凹凸不平的结构。在Pt纳米粒子理论负载量为319%（质量分数）的情况下，Pt/C 32微球表现出了最佳的HER性能，10 mA/cm 2电流密度条件下过电势降至22 24 mV，Tafel斜率为56 23 mV/dec，电荷转移电阻为4 58 Ω，双电层电容值 C dl 为36 95 mF/cm 2。Pt/C 8、Pt/C 16、Pt/C 32的过电势均优于Pt负载量为20%（质量分数）的商业Pt/C催化剂，反映出制备所得铂负载介孔碳球具有较高的电催化性能。该研究结果为开发高电催化析氢效率的碳铂催化剂提供了重要参考。 undefined
