负载型金属催化剂的表面溢出效应(Spillover)是指吸附在金属上的物种可沿固体表面转移到担体上去的现象,是金属活性组分与担体相互作用的一个重要方面。近年来随着金属与担体之间强相互作用(SMSI)研究的逐渐深入,人们注意到溢出效应在SMSI中的重要作用。虽然提出溢出效应已有20多年的历史,并且人们采用不同的实验方法对此进行了广泛的研究,但对以分子筛为担体的负载型金属催化剂体系溢出效应的研究仍比较少。影
Spillover of supported metal catalysts refers to the phenomenon that species adsorbed on metal can be transferred onto the support along the solid surface and is an important aspect of the interaction between the metal active component and the support. In recent years, with the progress of the research on the strong interaction between metals and supports (SMSI), people have noticed the important role of spillover effect in SMSI. Although the spillover effect has been proposed for more than 20 years, and people have conducted extensive research using different experimental methods, there are still few studies on the spillover effect of supported metal catalyst supported on molecular sieve. shadow
