Abstract Capturing and utilizing CO 2 from the production process is key to solving excessive emission problem. hydrogenation with green hydrogen produce olefins an effective promising way utilize valuable chemicals. The can be produced by through two routes, i.e., -FTS (carbon dioxide Fischer–Tropsch synthesis) MeOH (methanol-mediated), among which has significant advantages over in practical applications due its relatively high conversion low energy consumption potentials. However, faces challenges of difficult activation selectivity. Iron-based catalysts are for their dual functionality catalyzing RWGS CO-FTS reactions. This review summarizes recent progress on iron-based via FTS route analyzes catalyst optimization perspectives additives, active sites, reaction mechanisms. Furthermore, we also outline principles rational design high-performance catalysts.

The thermocatalytic conversion of CO2 with green or blue hydrogen into valuable energy and commodity chemicals such as alcohols, olefins, aromatics emerges one the most promising strategies for mitigating global warming concerns in future. This process can follow either a CO2-modified Fischer-Tropsch synthesis route methanol-mediated route, latter being favored its high product selectivity beyond Anderson-Schulz-Flory distribution. Despite progress CO2-led over bifunctional metal/zeolite catalysts, challenges persist developing catalysts both activity due to complexity hydrogenation reaction networks difficulty controlling C-O bond activation C-C coupling on multiple active sites within zeolites. Moreover, different construction proximity modes bifunctionality involving redox-based metallic acidic zeolite have been explored, which not systematically reviewed derive reliable structure-reactivity relationships. To bridge this "knowledge gap", review, we will provide comprehensive critical overview contemporary research zeolite-confined metal alcohol zeolite-based tandem/cascade catalytic systems C2+ hydrocarbons via route. Accordingly, special emphasis be placed evaluating how confinement effects "redox-acid" influence outcomes, particularly regarding selectivity, has also analyzed from mechanistic standpoint. review examine synergistic interactions among various catalyst components that govern catalysis, offering insights rational design new improved systems. By discussing current recognizing future opportunities using aims contribute advancement sustainable efficient processes valorization.

Selective hydrogenation of carbon dioxide (CO2) into value-added chemicals has aroused great interest. The chemical inertness CO2 and diverse reaction pathways usually require the construction enabled catalysts. To date, cobalt (Co) catalysts characteristic metallic and/or divalent Co components show potential for hydrogenation. better regulate hydrogenation, it is necessary to summarize current progress selective CO2. In this Perspective, first, methane over sites introduced. Second, methanol C2+ alcohols discussed by constructing mixed-valent sites. Third, light olefins C5+ liquid fuels cobalt-containing hybrid Fourth, paths are illustrated. Finally, challenges prospects cobalt-based nanocatalysts proposed.

There are obstacles with using conventional nanoparticle catalysts for developing atomic-by-atom tailoring of active sites in the heterogeneous catalysis field. However, atomically precise metal clusters formulas and crystallographically determined structures, which may build a bridge between single atoms nanoparticles, become possible to unravel respective contributions every atom cluster its overall catalytic performances structure–property relationship at an atomic-precision level. In this Review, we will first describe recent advances CO2 electronic reduction catalyzed by Au-based including pure gold alloys. We then put particular emphasis on chemical fixation into organic molecules, such as alkyne, epoxide, amine, over catalysts. Additionally, concisely introduce discovery selectivity hydrogenation toward C1 C2 products. Finally, provide our perspectives some issues conversion future research.

Abstract The CO 2 methanation is an important component of the “power to gas” strategy, and Ru‐Al O 3 catalyst considered be a state‐of‐the‐art for this reaction. Conventional prepared by wet impregnation. Due weak interactions between Ru Al , construction controllable interface metal substrate still challenging. In work, UV pulse laser used controllably construct ultra‐small nanoparticles on defects‐rich 3‐x ‐L in situ grown foil (Ru‐Al ‐L) effective photothermal methanation. catkin‐like fluff efficiently traps light ensure adsorption ‐L. defects anchors Ru. A Strong‐Metal‐Support‐Interaction (SMSI) effect constructed exhibits remarkable catalytic performance (CH 4 yield 12.35 mol g −1 h ) closed batch system. Then innovative flow reactor established based one‐piece microchannel catalyst. Thanks local pressure edge microchannels, CH further enhanced 14.04 . Finally, outdoor setup demonstrates feasibility 18.00 mmol min ). This work provides novel perspectives multi‐level micro/nanostructures integrated catalysts

With the rapid economic development, excessive use of fossil fuels and massive emission carbon dioxide (CO2), as a greenhouse gas, have aroused series environment issues. Direct CO2 hydrogenation to value-added chemicals using renewable energy is an effective strategy reduce dependence on fuels. Among these chemicals, light olefins liquid attracted attention both academic industry one most important in our daily life. Light can be produced from via modified Fischer-Tropsch synthesis (FTs) route or methanol-mediated process. Compared with process, FTs favorable for due its lower consumption higher conversion efficiency. Although great progress has been made fuels, designing efficient catalysts effectively control activation C-O bond growth C-C remains challenge. This review highlights research advances thermocatalytic pathway. The catalyst design, reaction mechanism, component, key factors affecting catalytic performance are summarized analyzed purpose this provide comprehensive view inspire development novel future.
