2021年7月15日 · Cu–ZnO–Al2O3 catalysts are used as the industrial catalysts for water gas shift (WGS) and CO hydrogenation to methanol reactions.

2025年2月1日 · Herein, Cu-ZnO interfaces were precisely regulated by depositing thin ZnO films on copper phyllosilicates (CuSiO 3) through atomic layer deposition (ALD) to prepare Cu/ZnO/SiO 2 composite catalysts (denoted as x ZnO/CuSiO 3, x is the number of ALD cycles) for CO 2 hydrogenation to methanol.

CO 2 activation takes place at the interfacial Cu/ZnO site. Water evolution occurs at Cu sites, avoiding poisoning of the interfacial site. MeO* hydrogenation to MeOH is the most energy-demanding process.

2025年1月27日 · Here, we report on the structural dynamics of a Cu/ZnO/ZrO 2 catalyst at 90 bar and 40 % CO 2 conversion (at equilibrium conditions), investigated in a dedicated metal-based spectroscopic cell specially fabricated using additive manufacturing.

2025年2月14日 · The spatially confined Cu–ZnO nanoparticles inside ZSM-5 frameworks facilitated suppressed nanoparticle aggregation by preserving major Cu + phases of active copper species, which contributed to excellent catalytic performance with CO 2 conversion rate of up to 20.8% and a methanol/DME selectivity of 81.6% (DME selectivity of 62.2%) with a ...

2024年5月8日 · The Cu/ZnO system represents an intriguing and intensively studied example of catalytic synergy between a metal (Cu) and a metal oxide (ZnO), since the catalytic turn-over rate towards...

2023年9月20日 · This fundamental understanding will greatly help to fabricate efficient Cu-ZnO-based catalysts for the CO2 hydrogenation to methanol. Cu-ZnO-based catalysts are widely used to catalyze the CO2 hydrogenation to methanol and reverse water-gas shift (RWGS) reactions.

2024年3月28日 · The Cu/ZnO/Al 2 O 3 catalyst derived from hydrotalcite-like precursor (CZA-LDH) exhibits the maximum Cu 0 specific surface area, the smallest Cu particle size, and high dispersion of elements, yielding the largest methanol production rate, which is comparable to the commercial Cu catalyst.

2021年12月29日 · Integrating Cu with ZnO (a CO-generation catalyst) is a strategy explored in the EC CO 2 reduction to reduce the kinetic barrier and enhance C–C coupling to obtain C 2+ chemicals and energy carriers.
