LaFeO3-supported nano Co-Cu catalysts for higher alcohol synthesis from syngas

Synergetic effect of copper species as cocatalyst on LaFeO3 for enhanced visible-light photocatalytic hydrogen evolution

“…CuO x and Cu [16] have both been frequently studied as efficient and economically feasible cocatalysts for TiO 2 to facilitate the charge-separation process and thus enhance the activity of the photocatalytic H 2 production. It has been reported that LaFeO 3 possesses good stability in reducing atmospheres; however, copper ions in the perovskite lattice are easily reduced and transform into metallic copper [17]. Thus, this work aims to synthesize copper cocatalysts supported on the perovskite-type oxide LaFeO 3 by a reduction-treatment and to investigate the synergetic effect of this cocatalyst on LaFeO 3 for the photocatalytic hydrogen evolution by visible-light water splitting.…”

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.…”

Remarkably efficient CoGa catalyst with uniformly dispersed and trapped structure for ethanol and higher alcohol synthesis from syngas

“…One of the approaches is to build bimetallic catalyst systems, such as CoPd [31] or CoCu [32][33][34][35][36][37][38]. The selectivity to C 2+ alcohols is thereby enhanced, as CO adsorption on Pd 0 or Cu 0 is associative rather than dissociative.…”
