Hydrogen spillover in the Fischer-Tropsch synthesis: the role of platinum and gold as promoters in cobalt-based catalysts
… (LTFT) synthesis involves the catalytic hydrogenation of carbon monoxide with the aim to produce long-chained hydrocarbons. Commercial cobalt-based catalysts incorporate oxidic supports that are known to negatively affect the reducibility and hinder formation of the active phase. …

AuPt nano-alloys as reduction promoters for Co/TiO₂ Fischer-Tropsch catalysts
… of Co₃O₄ to the catalytically active metal, Co⁰. Hydrogen spillover is thought to be the dominant mechanism for the functioning of noble metals during the reduction process. Platinum is a well-known reduction promoter and its functioning as a reduction promoter is thought to occur via H₂ - …

Hydrogen sorption in palladium doped microporous materials
This research investigated “hydrogen spillover” which has been suggested to improve the hydrogen uptake of bridged and chemically doped porous materials at room temperatures. XRD, Temperature Programmed Desorption and hydrogen sorption measurements were used to characterise the as-received and …

Interactions of hydrogen with alkali promoted Ru/SiO2 catalysts: a proton NMR study
… catalysts. Initial work investigated the role of hydrogen spillover to the silica support on the characterization of the active metal sites via a hydrogen chemisorption technique. A strongly bound component of spilled over hydrogen was found in the silica support which interfered with accurate …

NEW GO- AND RGO-BASED MORALS AND CARBENE-FUNCTIONALIZED GOLD NANOPARTICLES FOR HETEROGENEOUSLY CATALYZED REDUCTIONS
… modify catalytic materials for the study of the hydrogen spillover phenomenon, a process in which activated hydrogen atoms migrate from a metal surface onto an adjacent support. Understanding and controlling spillover is of considerable interest, as it can influence reaction pathways, extend the …
