Abstract:

Advances in catalysts for liquid-phase selective oxidation of toluene are reviewed according to the types of catalysts developed，such as transition metal oxides and supported transition metal oxides，heteropolyacids and supported heteropolyoxometalates，metal complexes and immobilized metal complexes，molecular sieve based catalysts and catalysts in supercritical CO₂. Properties and performance of these catalysts are comparatively summarized，and the development of effective catalyst for the reaction is discussed. It is proposed that effective green catalyst developed by the guidance of the function-properties relation is necessary for obtaining selective oxidation products with high yield.

摘要：

以过渡金属氧化物及其负载型催化剂、杂多酸及其负载型催化剂、过渡金属络合物及其负载型催化剂、沸石分子筛基催化剂、超临界CO₂介质催化反应体系为线索，评述了各类甲苯液相选择氧化反应催化剂的特性和近年来的研究进展，展望了甲苯液相选择氧化反应催化剂的发展方向，提出以反应对催化剂的结构和性质为指导来研制高效、“绿色”的催化剂仍是甲苯液相选择氧化反应的关键。
