| 燃料电池(FC)的电极催化剂密切影响电池的性能指标，开发高效、廉价、抗毒的催化剂是发展高性价比FC的关键。本项目以性能优异的石墨烯替代炭黑作为催化剂载体，以FC用石墨烯负载非铂催化剂 (GENPC) 为研究对象，运用各种化学方法设计合成新型的GENPC；系统研究石墨烯基复合结构中无机纳米晶尺寸、形状控制合成的特点和规律，探寻影响纳米晶在石墨烯片上均匀分布的关键因素，为实现可控合成提供实验基础。同时，探索集成电极的制备方法，尝试实现GENPC与电极的一体化制作。在此基础上用电化学方法研究GENPC对氧气还原、甲醇氧化的催化作用，探讨催化剂粒子的组成、状态及石墨烯还原程度、表面官能团、掺杂等对催化性能的影响；利用密度泛函理论研究GENPC的能带结构，探寻催化活性组分与石墨烯间的协同作用机制；揭示石墨烯载体影响催化活性的机理，为石墨烯载体的实际应用和高性能FC非铂催化剂的研发奠定实验和理论基础 |

忽然有事情,先翻译一半 The electrode catalyst for fuel cell (FC) greatly affects the performance of the cell, thus the development of efficient, inexpensive and anti-poisoning catalysts is the key to the development of FC with high performance-cost ratio. In the project, graphene with excellent performance was used to substitute for carbon black to be used as a catalyst carrier, a graphene-supported non-platinum catalyst (GENPC) for FC was selected as a research object, and novel GENPC was designed and synthesized by using various chemical methods; and the characteristics and laws on controlling synthesis of the size and shape of inorganic nano-crystals in the graphene-based composite structure were systematically researched, and the key factor affecting the uniform distribution of the nano-crystals on graphene sheets was explored, thereby providing the experimental basis for the realization of the controllable synthesis. |

由于时间仓促, 请作者再仔细斟酌. At the same time, the preparation method of integrated electrodes was explored, and the integrated manufacture of the GENPC and electrodes was achieved. On the basis, the catalysis of the GENPC on oxygen reduction and methanol oxidation was researched through an electrochemical method; the influence of the composition and state of the catalyst particles as well as reduction degree, surface functional groups, doping and the like of graphene on the catalytic performance was investigated; energy band structure of the GENPC was researched by using a density functional theory, thereby exploring the synergy mechanism between the catalytic active component and graphene; and the mechanism of the influence of the graphene carrier on the catalytic activity was revealed, thereby laying experimental and theoretical basis for practical applications of the graphene carrier and the research and development of high-performance non-platinum catalysts for FC. |
