摘要:

铂基金属催化剂在许多重要的液相加氢化学转化中起着至关重要的作用,研究尺寸、晶型及形貌可控的催化剂以制备铂利用率高及活性好的催化剂具有重要意义。本文系统地介绍了铂基金属催化剂的研究进展,包括不同铂基金属纳米催化剂的合成方法、还原剂的种类以及影响铂基催化剂性能的重要因素(包括粒子粒径、形貌、组成、载体)对催化活性和选择性的影响。铂基催化材料催化效率高但价格昂贵,文中指出进一步探索铂基催化剂对加氢反应机理的影响机制,降低成本的同时提高催化剂寿命并实现铂基催化剂的可控制备仍是未来的重点研究方向。

Abstract:

Platinum based catalysts play an important role in many important liquid phase hydrogenation reactions. It is of great significance to develop catalysts with controllable size, crystal shape and morphology so as to provide high platinum utilization rate and good activity. The latest research progress of platinum based catalysts is systematically reviewed in this paper, including the synthesis methods of different platinum nanocatalysts, the types of reducing agents, and the influence of important factors (including particle size, morphology, composition and carrier) on the catalytic activity and selectivity of platinum-based catalysts. Despite of their high catalytic efficiency, Platinum-based catalytic materials are still very expensive, so further exploring the hydrogenation mechanism of platinum-based catalysts, increasing the catalyst life while reducing the cost and realizing their controllable preparation are still the key research directions in the future.

Key words: platinum-based catalyst, support, nanoparticles, hydrogenation, morphology, preparation methods
