It is necessary to separate CO from biogas to improve its quality for the production of biomethane. Herein, an improvement in the separation of CO/CH adsorption was achieved by modifying the surface of CMS. The surface modification of CMS was performed by impregnation with metal oxide (FeO) and N-doping (DES-[ChCl:Gly]). Subsequently, the efficacy of the surface-modified CMS was investigated. This involved CMS modification, material characterization, and performance analysis. The uptake of CO by CMS-DES-[ChCl:Gly] and CMS-FeO was comparable; however, their performance for the separation of CO/CH was different. Consequently, CMS-DES-[ChCl:Gly] and CMS-FeO exhibited 1.6 times enhanced CO uptake capacity and 1.70 times and 1.55 times enhanced CO/CH separation, respectively. Also, both materials exhibited similar repeatability. However, CMS-DES-[ChCl:Gly] was more difficult to regenerate than CMS-FeO, which is due to the higher adsorption heat value of the former (59.5 kJ).

Converting CO into CO, CH, and other hydrocarbons using solar energy presents a viable approach for addressing energy shortages. In this study, photocatalysts with S-deficient WO/ZnInS (WO/V-ZIS) S-scheme heterojunctions have been successfully synthesized. Under UV-vis light irradiation, 20 %WO/V-ZIS demonstrated significantly improved CO reduction activity and CH selectivity.

Constructing nanoreactors with multiple active sites in well-defined crystalline mesoporous frameworks is an effective strategy for tailoring photocatalysts to address the challenging of CO reduction. Herein, one-dimensional (1-D) mesoporous single-crystal TiO nanorod (MS-TiO-NRs, ≈110 nm in length, high surface area of 117 m g, and uniform mesopores of ≈7.0 nm) based nanoreactors are prepared via a droplet interface directed-assembly strategy under mild condition.

Visible light-active photocatalysts play a crucial role in gas-phase photocatalytic CO reduction, offering significant potential for sustainable energy conversion. Herein, we present the synthesis of spindle-shaped Iron (Fe)-based metal-organic framework (MOF) MIL-88 A, coupled with distinct α-BiO nanospheres. The α-BiO/MIL88A heterostructure is formed by interacting opposite surface charges, enhancing visible-light absorption and efficient interfacial charge-carrier separation.

Carbon dioxide capture and utilization is a strategic technology for moving away from fossil-C. The conversion of CO into fuels demands energy and hydrogen that cannot be sourced from fossil-C. Co-processing of CO and water under solar irradiation will have a key role in the long-term for carbon-recycling and energy products production.

The zeolite-catalyzed conversion of DME into chemicals is considered environmentally friendly in industry. The periodic density functional theory, statistical thermodynamics, and the transition state theory are used to study some possible parallel reactions about the hydrogen-bonded DME over zeolite ferrierite. The following are the key findings: (1) the charge separation probably leads to the conversion of a hydrogen-bonded DME into a dimethyl oxonium ion (i.
