In situ APPES technique demonstrates that the strong metal support interaction effect (SMSI) in the Ni-ceria system is associated with the decoration and burial of metallic particles by the partially reduced support, a phenomenon reversible by evacuation at high temperature of the previously absorbed hydrogen.
原位 APPES 技术表明,Ni-氧化铈体系中的强金属支撑相互作用效应(SMSI)与部分还原支撑物对金属颗粒的修饰和掩埋有关,这种现象可以通过先前吸附的氢在高温下抽空来可逆。
