本文用低温氮吸附、X-射线衍射分析测定了钯催化剂载体的比表面和晶相。用H_2-O_2滴定、透射电镜、ESCA能谱仪测定了钯的分散状态和钯的化学状态。考察了过量氧下的氢氧反应对载体和催化剂上述性质的要求。结果表明,在一定范围内,该反应对钯催化剂载体的性质、催化剂的制备条件以及钯的晶粒大小要求不严。因而进一步论证了该反应属于非构敏性反应。 In this paper, the specific surface and crystal phase of palladium catalyst support were determined by low temperature nitrogen adsorption and X-ray diffraction analysis. H 2 O 2 titration, transmission electron microscopy and ESCA spectroscopy were used to determine the palladium dispersion and the chemical state of palladium. The requirements of the above properties of the support and the catalyst for the hydrogen-oxygen reaction under excess oxygen were investigated. The results show that, to a certain extent, the reaction on the nature of the palladium catalyst support, the preparation conditions of the catalyst and the grain size of palladium is not strict. Thus further demonstrated that the reaction is non-sensitized reaction.
