中文摘要：
碳化硅（sic）具有较好的导热性，较强的抗氧化性及很高的机械强度，作为新型催化剂载体在强放热、高腐蚀性、液相催化等反应中有很好的应用前景，近年来受到广泛关注。目前关于SiC载体的研究主要集中在三个方面：（1）高比表面积多孔SiC材料的制备；（2）基于现有商业化低比表面积SiC材料的表面碳化；（3）对SiC载体进行杂原子掺杂等表面功能化。本文中，我们主要对以上三个方面的研究现状做简要综述。重点介绍SiC的结构与物理化学性质，SiC作为新型载体在非均相催化反应中的应用以及基于6H—SiC（0001）衬底的表面化学研究。
英文摘要：
In recent years, increasing attention has been attracted for silicon carbide （SiC） in the field of catalysis as a potential catalyst support owing to its excellent thermal conductivity, relative chemical inertness, and high mechanical strength. SiC-supported catalysts are reported to exhibit superior catalytic performance in strong exothermal, severely corrosive and liquid-phase reactions. Nowadays, the researches towards SiC as a catalyst support focus on the following issues： the synthesis of high surface area SiC, the formation of carbide- derived carbon （CDC） on the low surface area SiC, and the surface functionalization of SiC. In this review, we address all of the above-mentioned issues. This article is arranged in three sections ranging from the experimental results over technical SiC-supported catalysts to surface chemistry studies on SiC single crystals. The first section introduces the structure and properties of SiC ; the second section covers SiC as a novel support in heterogeneous catalysis; and the surface science studies on the 6H-SiC（0001 ） substrate are highlighted in the last section.
