摘　　要：采用热失重法考察了氧化钴催化剂对氯酸钠催化分解的性能，结果表明由低温制备的氧化钴具有较高的催化性能，其催化的氯酸钠分解反应呈现固相分解的特点。通过XRD和XPS对氧化钴的结构进行了表征，并结合表征结果对氧化钴催化氯酸钠分解的机理进行了研究。研究结果表明制备温度的差异导致了氧化钴表面性质的差异，并对分解反应过程中的竞争反应产生了选择性，导致氧化钴催化性能不同。The catalytic performances of cobalt oxide catalysts for the decomposition of sodium chlorate were investigated by thermogravimetric analysis method. The results showed that the cobalt oxide prepared at low temperature exhibited higher performance, and catalyzed the sodium chlorate decomposing in a solid-phase reaction mode. The cobalt oxide structure was characterized by XRD and XPS and based on these result, the catalytic mechanism of cobalt oxide for decomposition of sodium chlorate was studied. The study indicated that the difference of cobalt oxide surface property induced a selective reaction, and decided a different catalytic performance.
