NASA is using the Sabatier reaction to recover water from exhaled carbon dioxide and the hydrogen previously discarded from electrolysis on the International Space Station and possibly for future missions. [17][18] The other resulting chemical, methane, is released into space.

2021年2月1日 · Replacing fossil fuels with renewable energy sources has a fundamental role in creating a sustainable and carbon-free economy. The catalytic hydrogenation of CO 2 has great potential to reduce an enormous amount of CO 2 and contribute to a green economy by converting CO 2 into a variety of useful products.

2015年10月22日 · The catalytic reduction of CO 2 by H 2 can lead to the formation of three types of products: CO through the reverse water–gas shift (RWGS) reaction, methanol via selective hydrogenation, and hydrocarbons through combination of …

Reduction of CO2 with hydrogen into CH4 is studied for the first time on carbon‐nanotube‐supported Co and Ni catalysts under supercritical conditions. The extremely high selectivity toward...

2017年5月2日 · Here we report a highly efficient, stable and multifunctional Na–Fe 3 O 4 /HZSM-5 catalyst, which can directly convert CO 2 to gasoline-range (C 5 –C 11) hydrocarbons with selectivity up to 78%...

2023年10月3日 · The Sabatier reaction, named after the French chemist Paul Sabatier, is a catalytic hydrogenation reaction that converts CO2 and hydrogen (H2) into methane (CH4) and water (H2O): CO2 + 4H2 → CH4 + 2H2O. This reaction is exothermic, releasing heat as a …

2019年12月13日 · Thermocatalytic hydrogenation of CO 2 to methane can be achieved easily at atmospheric pressure and high gas hourly space velocity (GHSV), and has been shown to achieve CO 2...

Carbon dioxide hydrogenation is a promising reaction that is widely researched due to its ability to produce clean fuels and hydrocarbons such as CO, CH4 and C 2+ products. The hydrogenation reaction can proceed via thermal catalysis, photocatalysis and photothermal catalysis.

2025年3月9日 · Three processes are covered for catalytic CO2 conversion and H2/syngas production, namely thermal, plasma-assisted and membrane-assisted catalysis. In the thermal catalysis, four catalyst modification strategies (size control, interface engineering, surface regulation and oxygen species) are critically illustrated by referring the structure ...

2020年5月7日 · A lab.-scale reactor system was built and operated to demonstrate the feasibility of catalytically reacting carbon dioxide (CO2) with renewably-generated hydrogen (H2) to produce methane (CH4) according to the Sabatier reaction: CO2 + 4H2 → CH4 + 2H2O.
