Higher alcohol synthesis from syngas over xerogel-derived Co-Cu-Al2O3 catalyst with an enhanced metal proximity

Rational Design of Catalysts with Spinel Nanostructures for Thermal-Driven C1 Conversion

“…Spinel precursors are favorable to generate neighboring dual sites for the synergic effect. Fe–Cu − and Co–Cu − bimetallic catalysts derived from spinel precursors have been developed, in which iron carbides and metallic Co are regarded for CO dissociation and chain growth, while metallic Cu is responsible for nondissociative CO adsorption and insertion . Even so, suffering from limited solubility, phase separation seems to be inevitable in bimetallic catalysts.…”

Recent advances in the routes and catalysts for ethanol synthesis from syngas

“…Consequently, they found that an optimal ratio and high proximity of Co/Cu are important factors in alcohol synthesis from syngas. 110…”

Unraveling the Surface Structure of Ceria-Supported Bimetal Co–Cu Nanoparticles

“…9 The appropriate distribution of Cu and Co atoms in the Co− Cu/Al 2 O 3 system significantly improved the catalytic activity and selectivity of the syngas reaction. 8 Despite tremendous studies on real catalysts, the surface structure and composition of active phases in the Co−Cu bimetallic systems in catalytic reactions are still under debate. For instance, in the higher alcohols synthesis reaction, de Jongh et al suggested that the active phases were the alloy-type mixed Cu−Co sites of the CuCo/MoO x catalysts, with Co-enriched compositions.…”

“…Co–Cu bimetallic systems have demonstrated remarkable catalytic activity in many reactions, such as CO/CO 2 hydrogenation, CO oxidation, and water–gas shift (WGS) reactions. − For example, the mesoporous Co–Cu/CeO 2 structure has been identified as providing suitable CO adsorption sites and yielding high WGS catalytic activity . The appropriate distribution of Cu and Co atoms in the Co–Cu/Al 2 O 3 system significantly improved the catalytic activity and selectivity of the syngas reaction . Despite tremendous studies on real catalysts, the surface structure and composition of active phases in the Co–Cu bimetallic systems in catalytic reactions are still under debate.…”
