A DFT investigation of the mechanisms of CO2 and CO methanation on Fe (111)
Insight into the detailed mechanism of the Sabatier reaction on iron is essential for the design of cheap, environmentally benign, efficient and selective catalytic surfaces for CO2 reduction. Earlier attempts to unravel the mechanism of CO2 reduction on

A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

Ni Nanoparticles on Reducible Metal Oxides (Sm2O3, CeO2, ZnO) as Catalysts for CO2 Methanation
The activity of reducible metal oxide Sm2O3, CeO2, and ZnO as Ni nanoparticles support was investigated for CO2 methanation reaction. CO2 methanation was carried out between 200 °C to 450 °C with the optimum catalytic activity was observed at 450 °C. The

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Methanation of CO2 on supported rhodium catalyst [PDF]
Abstract The synthesis of methane from CO 2 and H 2 was investigated on supported Rh catalysts. The adsorbed species present on the catalysts were characterized by infrared spectroscopy. The hydrogenation of CO 2 on Rh Al 2 O 3 occurred at a measurable rate above 443 K, yielding exclusively methane. The rate of methane formation on

VOx promoted Ni catalysts supported on the modified bentonite for CO and CO2 methanation
Ni catalysts supported on the raw bentonite (RB) and the acid-alkali treated bentonite (B), which were prepared by the impregnation method, were tested for methanation of CO2 and CO respectively to produce synthetic natural gas (SNG).
