The origin of the mediocre methanol selectivity of Cu/ZnO-based catalysts for methanol synthesis from CO2 hydrogenation

Mn-promoted MoS2 catalysts for CO2 hydrogenation: enhanced methanol selectivity due to MoS2/MnOx interfaces

“…In addition to such materials, other recent lines of research involve the search for novel catalysts, since the application of copper-based materials is still limited by the instability of the active phase, 15 low selectivity to methanol 16 and surface poisoning in the presence of sulfur-containing gases. 17 In virtue of these issues, non-metallic catalysts such as ZnZrO x (ref.…”

High-Performance Cu/ZnO/Al2O3 Catalysts for CO2 Hydrogenation to Methanol

“…However, the rarity and high cost of noble metals limit their potential for large-scale applications. In 2 O 3 has been proven theoretically and experimentally to be highly selective for CO 2 hydrogenation to methanol. , The surface of h -In 2 O 3 (104) exhibits excellent catalytic performance, and the three coordinated Ov sites on c -In 2 O 3 facilitate the formation of CH 3 OH rather than CO. , Numerous studies have found that loading precious metals (Pd, Pt, Rh, and Ru) can effectively enhance In 2 O 3 -based hydrogen activation ability. − Wang et al discovered the ZnO-based solid–solution catalyst system, where ZnZrO x has become an efficient choice for CO 2 hydrogenation to methanol, and has been extensively studied on the basis of solid–solution catalysts. − Cu-based catalysts, as the most widely used catalyst system for CO 2 hydrogenation to methanol, exhibit low cost and excellent activity and have been applied in industrial production. − For example, Cu-based catalysts derived from layered double hydroxide (LDH) have been reported to exhibit high activity and excellent stability over an operation time of 2400 h. , However, the active sites of Cu-based catalysts have not been clearly resolved.…”
