一、前言钼和钨的一些杂多化合物已有广泛的应用,特别是其在催化领域所起的作用更加引人注目,用杂多化合物做为催化剂的某些有机合成已投入了工业生产。某些稀土杂多化合物已显示出较好的催化性能。所以,稀土杂多化合物的制备及有关的研究已成为多酸化学进入七十年代后的一个新方向。本文试图对镧系元素杂多化合物七十年代后的 I. INTRODUCTION Some heteropoly compounds of molybdenum and tungsten have been widely used. In particular, their role in catalysis is even more remarkable. Some organic syntheses using heteropoly compounds as catalysts have been put into industrial production. Some rare earth heteropoly compounds have shown good catalytic performance. Therefore, the preparation of rare earth heteropoly compounds and related research have become polyacid chemistry into the seventies after a new direction. This article attempts to lanthanide heteropoly compounds after the seventies
