负载型非晶态合金的结构及催化加氢性能

采用还原法制备了负载型Ni-B、Ni-P体系非晶态合金催化剂，对其结构进行了物化表征。该方法制备的非晶态合金克服了以往制备方法的非晶态合金比表面积小、热稳定性差的缺点。以甲苯、苯乙烯、苯乙炔、硝基苯、环己酮和己二腈为模型化合物，研究了负载型非晶态合金的催化加氢反应性能，并与多晶Ni催化剂进行对比。结果表明，非晶态合金具有更优越的催化加氢性能，并有可能作为含不同不饱和基团化合物的选择加氢催化剂。

Structure and catalytic hydrogenation properties of supported amorphous alloy catalysts

Supported Ni-B and Ni-P amorphous alloy catalysts were prepared by chemistry reduction.Structure of the catalysts was studied by XRD,thermal analysis and TEM.The amorphous alloy prepared by chemical reduction overcame the disadvantages with those prepared by traditional small,(i.e.,) low surface area and poor thermal stability.The behaviors of the catalysis were investigated using toluene,styrene,benzyl ethane,nitrobenzene,cyclohexanone and adipic dinitrile as the model compounds and compared with that of crystal nickel catalysts.The experimental results showed that amorphous alloys have better catalytic properties for hydrogenation and are promising as the catalysts for hydrogenation of compounds with unsaturated groups.
