Preparation of bimetal Cu–Co nanoparticles supported on meso–macroporous SiO2 and their application to higher alcohols synthesis from syngas

Effects of Cu/Fe ratio on structure and performance of attapulgite supported CuFeCo-based catalyst for mixed alcohols synthesis from syngas

“…Ding et al [20,21] reported that, because of the well dispersion of active metal sites and high diffusion efficiency of products inside the bimodal pore structures, the SiO 2 -SiO 2 bimodal pore catalyst with high specific surface area and unique porous structure exhibited favorite catalytic activity and high selectivity of C 2+ OH. Liu et al [22] prepared a series of LaCo 0.7 Cu 0.3 O 3 /meso-macroporous SiO 2 catalysts, in which both the ions of copper and cobalt were located in perovskite structures and could be highly dispersed at atomic level, resultantly, the formed core-shell structure of Co@Cu bimetallic nanoparticles favored the alcohols synthesis and the porosity of the meso-macroporous SiO 2 support favored the diffusion of the reactants and the reacted products. Therefore, the development of catalyst support is still an important theme.…”

Effects of impregnation strategy on structure and performance of bimetallic CoFe/AC catalysts for higher alcohols synthesis from syngas

“…Liu et al [23,24] demonstrated that higher alcohols synthesis over the meso-macroporous SiO 2 and LaFeO 3 supported Co-Cu catalysts were related to both the Co-Cu alloy and Co 2 C species. Davis et al [7] deduced that the Co 2 C species could enhance the oxygenates selectivity in the F-T synthesis.…”

Nanoparticles of Cu–Co alloy derived from layered double hydroxides and their catalytic performance for higher alcohol synthesis from syngas

“…One is meso pores in size of several nanometers, and the other in size of tens nanometers. The former is proposed to be formed from the left of CO3 2and water in LDHs in the calcination process, and the latter came from the accumulation of oxides particles. From the SEM images, it is seen the particle size is in tens nanometer, in accordance for accumulating the pores.…”
