Abstract:Replacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental and practical catalysis research. Nanostructured graphene-based and transition metal materials have demonstrated promising catalytic properties in a wide range of energy generation/storage applications.Specifically engineering graphene with guest metals/metal-free atoms can improve its catalytic activity for electrochemical oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thus can be considered as potential substitutes for the expensive Pt/C or IrO2catalysts in fuel cells, metal-air batteries and water splitting process. In this presentation, we will talk about the synthesis of nonprecious metal and metal free elements-doped graphene, and their application on electrocatalysis . The excellent ORR, OER and HER performance (high catalytic activity and efficiency) and reliable stability (much better than the commercial Pt/C or IrO2) indicate that newmaterialsare promisinghighly efficient electrocatalysts for clean energy conversion.

摘要:目前,纳米结构碳和石墨烯在能源存储和转换中具有广泛的应用前景。特别是杂原子功能化的石墨烯和孔性碳材料能够明显改进原有碳材料的氧还原反应(ORR)和产氧反应(OER)催化的活性,因而有望替代昂贵的Pt/C催化剂在燃料电池及金属空气电池等装置上得到应用。基于当前研究背景,我们开展了相关研究工作,并报道了非金属元素修饰的石墨烯材料(B,N-graphene, S,N-graphene)、三维g-C3N4@Carbon孔材料等材料的合成及它们在电催化反应中的应用。此报告将涉及相关实验方案设计、实验数据处理以及科研文章撰写等方面内容。
