This study evaluated the coupling reaction of CO2 with methane via trimetallic catalyst based on ZrO2/TiO2 to produce acetic acid. The catalysts were characterized by various techniques including XRD, BET for textural properties, NH3-TPD and H2-TPR. The surface acidity of trimetallic catalyst was ...
The electrochemical CO2 reduction reaction towards value-added fuel and feedstocks often relies on metal-based catalysts. Organic molecular catalysts, which are more acutely tunable than metal catalysts, are still unable to catalyse CO2 to hydrocarbons under industrially relevant current densities for long...

CH4 + 2O2→ CO2 + 2H2O CH4 + CO2→2CO + 2H2 CH4 + H2O→CO + 3H Hydrogen from syn gas reacts with nitrogen to produce ammonia: N2 + 3H2→2NH3. Carbon monoxide and hydrogen from syn gas can be combined to produce methanol: CO + 2H2→CH3OH. ...
during the stability test for 458 h: (a) CO2 conversion, (b) product consist of the calcined catalyst and the reduced catalyst. Meanwhile, the spent catalysts are obtained after the reaction with stability test for 458 h, collected from two reactors (SR1 and SR2) at three ...
Dry methane reforming (DMR) or CO2 reforming is the third common form of reforming process. In this process, syngas with a H2/CO ratio of 1:1 is produced according to the following reaction: (8)CH4+CO2⇔2CO+2H2,ΔH=247kJ/mol This reaction was originally proposed by Fischer and Trops...
Methane, the simplest alkane, is one of the most important and abundant carbon molecules on Earth. It is a major supply of energy, a chemical feedstock, and a potent greenhouse gas. Aside from thermogenic, pyrogenic, and abiotic sources, methane is prima

20,21,22,23]. For example, mixotrophically growing cultures ofMethanosarcina barkeriform their biomass equally from methanol and CO2; however, almost all the methane is formed from methanol rather than from CO2since methanol is disproportionated to methane and CO2according to the following reaction...
