To date, rutile iridium dioxide IrO2 is the only known OER catalyst in the acidic solution, while its poor activity restricts its practical viability. Herein, we propose a universal graph neural network, namely, …
Webb24 aug. 2024 · The water can be condensed from the reactor’s exhaust and electrolyzed to hydrogen and oxygen: The hydrogen can be fed back into the Sabatier reactor to produce more methane, while the oxygen can be stored as oxidizer for the rocket fuel or be used for breathing. A Starship would only bring enough fuel to reach the surface of Mars. WebbThe Sabatier reaction is exothermic, so it is really efficient, the major energy requirement is for electrolysis which is central to utilizing the Sabatier reaction - first to get hydrogen (if hydrogen isn't being imported from Earth), and secondly to get the oxidizer out of the resulting water, rockets are mostly filled with Oxidizer after all (also, this recycles …
