为了获得具有高导热系数的管壁反应器，采用化学镀法在铝板上制备镍催化剂，该方法包括用锌置换铝和化学还原沉积镍。因此，当通过甲醇分解生成一氧化碳和氢气时，镀覆的催化剂显示出高活性和高选择性。镀覆条件对镀覆催化剂的催化性能有显著影响。特别地，使用碱性镀锌浴和包括次磷酸钠作为还原剂的中性镀镍浴制备的镀覆催化剂具有最高的活性和最高的选择性。还表明置换操作和使用包括还原剂的镀镍浴是形成对铝基底具有强粘附力的均匀镀层的重要因素。
In order to obtain a tube-wall reactor with high thermal conductivity, nickel catalysts on an aluminum plate were prepared by electroless plating which consisted of displacement of aluminum by zinc and the deposition of nickel by chemical reduction. Thus plated catalysts showed high activities and high selectivities when forming carbon monoxide and hydrogen by methanol decomposition. The catalytic properties of the plated catalysts were significantly affected by the plating conditions. In particular, the plated catalyst prepared using an alkaline zinc plating bath and the neutral nickel plating bath that included sodium hypophosphite as the reducing agent had the highest activity and the highest selectivity. It was also shown that the displacement operation and the use of the nickel plating bath including a reducing agent was important factors forming a uniform plated layer having strong adhesion to the aluminum base.
