博士研究生程坤顺利通过博士学位论文答辩

2016年5月22日下午，我组博士研究生程坤顺利完成了博士答辩，在此表示祝贺！以下是程坤同学的答辩情况介绍：

质子交换膜燃料电池（PEMFC）是一种清洁和高效的能量转换装置。目前，其商用的贵金属（主要为Pt）基催化剂面临稳定性差等重要问题，这主要是因为担载贵金属催化剂的碳载体容易发生电化学氧化，导致金属催化剂颗粒移动、脱落或团聚，致使催化剂的活性降低。本文提出通过限域和锚定作用来提高Pt纳米颗粒与载体的相互作用以降低Pt纳米微粒运动的自由度，从而达到大幅改善燃料电池催化剂稳定性的目的。

徐峰同学博士毕业论文的答辩研究内容主要包括氧化铈（CeO2）的SO2/CO及混合催化剂的CO抗中毒性能。研究发现，随着CeO2含量的增加，Pt表面对CO的催化氧化能力也随着提高；而对SO2的催化氧化能力却逐渐降低，含有2 wt% CeO2的催化剂表现最好；研究认为，CeO2所提供的氧对SO2和CO的氧化起了至关重要的作用。此外，不同形貌的纳米氧化铈晶体，也表现出不同的抗SO2/CO中毒性能。论文对混合催化剂的CO抗中毒性能及机理也进行深入探讨。最后，针对研究工作中的不足，对今后的进一步工作进行了展望。

在完成自己博士在读期间研究工作的介绍后，徐峰同学对各位评委提出的问题作了认真解答，并保证按照所提的建议和意见对论文进行修改和完善。最后祝贺徐峰同顺利通过博士学位论文答辩，希望其在今后的工作中通过努力拼搏，取得更优异的成绩!

何大平同学就其研究工作——基于石墨烯(GNS)双功能作用与石墨烯三明治结构质子交换膜燃料电池催化剂，向在场的各位评委、老师及同学们作了详细介绍。他首先提出了GNS表面基团与石墨化程度对贵金属Pt催化剂稳定性的双功能作用，并确定了最佳的O/C原子比。在此基础上，分别利用全氟磺酸（PFSA）修饰、GNS表面磺化接枝及N掺杂处理，制备得到了一系列具有较高催化活性及电化学稳定性的GNS载Pt催化剂。研究过程中还发现了PFSA修饰对提高Pt催化剂抗CO中毒性能及N掺杂对GNS载Pt催化剂氧化原反应（ORR）稳定性有着积极的影响。最后，针对GNS二维片层结构的堆叠和团聚问题，制备出了具有三明治结构的GNS/纳米导电碳球复合材料，作为Pt催化剂载体，催化剂的催化活性与稳定性均得到较大提高。

在完成自己博士在读期间研究工作的介绍后，何大平同学对各位评委老师提出的问题作了认真解答，虚心接受了各种中肯的建议和意见。最后祝贺何大平同学完成其博士研究工作，顺利通过博士学位论文答辩，希望其在今后的工作中再接再厉，取得更大的成绩！
