摘要 过渡金属过氧化合物是一类性能良好的催化剂,在有机合成中得到广泛的应用[1,2].过氧多酸催化过氧化氢氧化有机物的反应,近年来倍受重视[3~5].文献中对过氧多酸的报道多以钨、钼为主[6],而性质相近的铌、钽报道则较少[7].本文合成了组成为[(C4H... The title compounds have been prepared by dissolving sodium niobate(or sodium tantalate) and sodium tungstate in 30% hydrogen peroxide solution at -5 ℃ and adjusting pH=1 with hydrochloric acid. The results of elementary analysis, TG DTG, IR, UV and XPS indicate that the title compounds have the hexametaiate type structure, and the O 2- 2 group is coordinated with niobium or tantalum.
