一、前言作为新型催化剂,杂多酸HPA及其盐的研究近年来得到了广泛的重视。我们实验室曾对一些杂多酸的物理化学性质和催化活性进行了系统的研究。本文将系统地考察配位原子钨和钼对H_3PMo_(12-n)W_nO_(40)(n=0—12)系列杂多酸的物理化学性质的影响。
I. INTRODUCTION As a new type of catalyst, the research of heteropoly acid HPA and its salt has gained wide attention in recent years. Our laboratory has conducted a systematic study of the physicochemical properties and catalytic activity of some heteropoly acids. In this paper, we systematically investigated the effects of coordination atoms such as tungsten and molybdenum on the physicochemical properties of H_3PMo_ (12-n) W_nO_ (40) (n = 0-12) series heteropolyacids.
