摘要:

金刚石是由共价键方式连接的sp3杂化碳原子组成, 具有极强的稳定性。含硼金刚石(BDD)薄膜、BDD颗粒、非掺杂纳米金刚石(ND)等新型金刚石又兼具一定的导电性, 因此成为高稳定性燃料电池催化剂的理想载体材料。研究者进一步发现通过对上述新型金刚石进行适当功能化处理, 可以进一步提高催化剂的催化活性和稳定性。对金刚石进行掺杂处理, 既包括向金刚石晶格中掺杂, 也包括向金刚石衍生的石墨结构中进行掺杂, 能够得到新型高稳定性燃料电池非铂催化剂, 且金刚石sp3结构在提高非铂催化剂稳定性方面作用独特。本文总结介绍了相关研究成果, 希望能为后续研究提供参考借鉴。

Abstract:

Attributed to highly stable structure of sp3 hybridized carbon atoms, diamond has excellent physical and chemical stabilities. As new conductive diamond materials, boron-doped diamond (BDD) films and particles, as well as undoped nanodiamond (ND) has become the ideal support of the high stability electrocatalysts for fuel cells. Futher investigation showed that the activity and stability of electrocatalysts could be futher improved if the new diamond materials were properly processed. The doping treatment, including doping into diamond and the graphite structure from conversion of diamond, was used to produce diamond-based non-Pt electrocatalysts for fuel cells. It was considered that the sp3 structure of diamond played a unique role in enhancing the stability of diamond-based non-Pt electrocatalysts. In this paper, related studies of diamond-based electrocatalysts were summarized for the references of future study.
