Recent advances in hydrogenation of CO₂ into hydrocarbons via methanol intermediate over heterogeneous catalysts

Abstract

This review provides recent advances in the conversion of CO2 to methanol, methanol to hydrocarbons, and direct conversion of CO2 to hydrocarbons via methanol intermediate over various monofunctional and bifunctional solid catalysts.

Removal of carbon dioxide using zeolitic imidazolate frameworks: Adsorption and conversion via catalysis

“…The conversion of CO 2 into hydrocarbons via hydrogenation is a promising method of making waste into valueadded materials. [10,[264][265][266][267][268][269][270][271][272][273] This reaction can solve the environmental and energy issues caused due to CO 2 emissions. Hydrogenation of CO 2 can be used to synthesize valuable compounds: (1) hydrocarbons, such as methane (CH 4 , the reaction can be called methanation), [270,274] olefins, and gasoline, or (2) other compounds, such as formic acid (HCOOH), alcohol (e.g., methanol), and carbon monoxide (CO).…”

A Review on Removal of Carbon Dioxide (CO2) using Zeolitic Imidazolate Frameworks: Adsorption and Conversion via Catalysis

“…The conversion of CO2 into hydrocarbons via hydrogenation is a promising method of making waste into value-added materials [10,[261][262][263][264][265][266][267][268][269][270] . This reaction can solve the environmental and energy issues caused due to CO2 emissions.…”

Hydrogenation can be promoted via electrochemical [272] , thermo-catalysis [273] , and photo/thermal [274] methods.…”

Single-atom catalysts for thermal- and electro-catalytic hydrogenation reactions

“…The compounds are not only limited to organic ones (such as alkynes, aldehydes, alkenes, ketones, nitroarenes, and so on), but also span a variety of inorganic ones (such as metal carbonates, nitrates, carbon dioxide, nitrogen, and so on). [6][7][8][9][10] The thermal-catalytic hydrogenation reaction, in most cases, uses gaseous hydrogen (H 2 ) as the hydrogen source to reduce unsaturated compounds with a suitable catalyst capable of dissociating hydrogen gas. For example, in the thermal-catalytic hydrogenation of alkynes under reaction conditions of 175 C and 0.1 MPa H 2 , ethylene could be obtained at 94% conversion over the Au/SiO 2 catalyst.…”
