本文提出了利用脉冲色谱技术研究氧化物催化剂表面金属离子数目及分布的分子探针新方法,并对不同组份及制法的V_3O_5、V_2O_5-P_2O_5体系催化剂作了具体测定.
In this paper, a new molecular probe method for the determination of the number and distribution of metal ions on the surface of oxide catalysts by pulse chromatography was proposed. The specific catalysts for V_3O_5 and V_2O_5-P_2O_5 systems with different components and preparation methods were also determined.
