| 摘要: 燃料电池是具有广泛应用前景的新能源技术。碳载铂基催化剂（Pt/C）是最常用的燃料电池电极催化剂，不过Pt/C稳定性较差、且成本高昂，严重限制了燃料电池的规模化应用。共价型碳化物碳化硅和碳化硼，由于具有极强的共价键，其物化稳定性优异，成为制备高稳定性、低成本的燃料电池催化剂的重要基础材料。本文总结了相关研究成果，介绍了碳化硅和碳化硼的独特优势，讨论了相关研究的发展方向。 | |

| Abstract: Fuel cells are considered to be new energy technologies with broad application prospects. Platinum nanoparticles loaded on carbon supports (Pt/C) are commonly used as electrode electrocatalysts for fuel cells, however, Pt based nanocatalysts are unstable in fuel cells and high cost, which severely restricting the scale application of fuel cells. Silicon carbide and boron carbide, which presents excellent physical and chemical stability due to strong covalent bonds, become stable and low cost materials for fuel cell catalysts. The progress of related research is reviewed in this paper, unique advantage of silicon carbide and boron carbide as electrocatalysts is provided, and development tendency is discussed. | |
