摘要

采用共沉淀法制备了一系列以Fe3O4纳米颗粒为载体的Ru-Ni双金属化合物磁性可分离催化剂。对这些催化剂进行了二甲酰基三环癸烷加氢反应的评价，在温和条件下，二甲酰基三环癸烷的转化率为98%，三环癸烷的选择性为97%。利用氧化铁载体的磁性可以很容易地回收催化剂。用x射线光电子能谱、x射线衍射和程序升温还原对催化剂进行了表征。这些互补的表征结果表明，优越的催化活性可能源于Ru和Ni之间的微妙协同作用。

Magnetically separable Fe3O4-supported Ru–Ni bimetallic catalysts for diformyltricyclodecanes hydrogenation to value-added fine chemicals

A series of magnetically separable catalysts based on Ru–Ni bimetallic compounds supported on Fe3O4 nanoparticles was prepared by the co-precipitation method. These catalysts were evaluated for diformyltricyclodecanes hydrogenation reactions, achieving 97% tricyclodecanedimethylol selectivity at 98% diformyltricyclodecanes conversion under mild conditions. The catalyst could be easily recovered by using the magnetic property of the iron oxide support. The catalysts were characterized with X-ray photoelectron spectroscopy, X-ray diffraction, and temperature-programmed reduction. These complementary characterization results suggested that the superior catalytic activity may be derived from the delicate synergy between Ru and Ni species.
