The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) [1] was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. [2] On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis.
Direct methanol fuel cells have been developed by Caltech's Jet Propulsion Laboratory to convert methanol and oxygen into electricity. [16] It is possible to convert methanol into gasoline, jet fuel or other hydrocarbons, but that requires additional energy and more complex production facilities. [ 4 ]
Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.

The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. [3] It is also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs), and DC-SOFC. The total reaction of the cell is C + O 2 → CO 2. The process in half cell notation: Anode: C + 2O 2− → CO ...
Numerous schemes have been described as artificial photosynthesis. Photocatalytic water splitting, the conversion of water into hydrogen and oxygen:; 2 H 2 O → 2 H 2 + O 2 This scheme is the simplest form of artificial photosynthesis conceptually, but has not been demonstrated in any practicable way.
The respiratory quotient (RQ or respiratory coefficient) is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body, when the body is in a steady state.
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
