Oxygen could also be produced in this way under water or in space -- without requiring stringent conditions such as pressure and temperature.

Hydrogen atoms play an important role as"mediators." However, the process is not particularly efficient. In addition, the oxygen produced does not come from the COis not taking place in plants and also could not be achieved at moderate temperatures by technical means so far. Ping He, Haoshen Zhou, and their team at Nanjing University, in collaboration with researcher from Fudan University have now achieved their goal to directly split COinto elemental carbon and oxygen. Instead of hydrogen, the"mediator" in their method is lithium. The team developed an electrochemical device consisting of a gas cathode with a nanoscale cocatalyst made of ruthenium and cobalt as well as a metallic lithium anode. CO, though the pressure is less than 1 % of the pressure of Earth's atmosphere. The simulated Mars atmosphere thus contained a mixture of argon and 1 % COIf the required power comes from renewable energy, this method paves the way toward carbon neutrality. At the same time, it is a practical, controllable method for the production of Owith broad application potential -- from the exploration of Mars and oxygen supply for spacesuits to underwater life support, breathing masks, indoor air purification, and industrial waste treatment.Scientists have taken a critical next step in creating a scalable process to remove carbon dioxide from the air and 'recirculate' it as a renewable fuel. Chemists now describe their ... Global warming continues to pose a threat to human society and the ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming. To ... Scientists have developed a way to convert carbon dioxide , a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. ... A recently discovered catalyst, can convert carbon dioxide into useful methanol at room temperature and low-pressure conditions. This novel compound, which is thermally and chemically stable in ...
