Actual problems of development of catalysts for hydrogenation of heterocyclic compounds by hydrogen are summarized and discussed. The scope of review covers composites of nanoparticles of platinum group metals and 3d metals for heterogeneous catalytic processes. Such problems include increase of catalyst activity, which is important for reduction of precious metals content; development of new catalytic systems which do not contain metals of platinum group or contain cheaper analogues of Pd; control of factors which make influence on the selectivity of the catalysts; achievement of high reproducibility of the catalyst‘s performance and quality control of the catalysts. Own results of the authors are also summarized and described. The catalysts were prepared by decomposition of Pd⁰ and Ni⁰ complexes, pyrolysis of Ni²⁺ and Co²⁺ complexes deposited on aerosil and reduction of Ni²⁺ in pores of porous support in situ. The developed catalysts were used for hydrogenation of multigram batches of heterocyclic compounds.

有机化合物多相加氢过渡金属催化剂的研究进展与挑战

对氢杂环化合物加氢催化剂开发中的实际问题进行了总结和讨论。审查范围涵盖用于多相催化过程的铂族金属和 3d 金属纳米颗粒复合材料。这些问题包括提高催化剂活性，这对于减少贵金属含量很重要；开发不含铂族金属或更便宜的钯类似物的新催化系统；影响催化剂选择性因素的控制；实现催化剂性能的高再现性和催化剂的质量控制。还总结和描述了作者自己的结果。通过Pd ⁰和Ni ⁰配合物的分解、气相二氧化硅上沉积的Ni ²⁺和Co ^{2+配合物的热解以及Ni 2+}在多孔载体孔中的原位还原制备了催化剂。所开发的催化剂用于多克批次杂环化合物的氢化。
