1981年,我们曾以乙烯基吡啶的共聚物为高分子载体,用固相合成的方法制备了一个高分子钼铁硫配合物催化剂(Ⅰ)。经光谱分析研究表明,它的催化活性中心具有钼铁硫原子簇结构。该催化剂对于以KBH_4为还原剂的乙炔加氢反应具有催化活性。沿用Schrauzer等的提法,该反应可作为研究固氮活性的模型反应。
In 1981, we used a vinylpyridine copolymer as polymer carrier to prepare a polymer molybdenum iron sulfur complex catalyst (Ⅰ) by solid-phase synthesis. The spectroscopic analysis shows that its catalytic activity center has a cluster of molybdenum iron sulfur atoms. The catalyst has catalytic activity for the hydrogenation of acetylene with KBH_4 as reducing agent. Following the formulation of Schrauzer et al., This reaction can serve as a model for studying nitrogen fixation activity.
