WebAn integrated process by coupling hydrothermal reactions, including CO2 reduction and H2O dissociation with metals, is proposed. The hydrogen could be rapidly produced under hydrothermal conditions, owing to the special characteristics of high temperature water, generating metal hydrides as intermediates. Hydrogen production from the H2O … WebReaction with hydrogen. With hydrogen, alkali metals form saline hydrides that hydrolyse in water. Na + H 2 → NaH (at high temperatures) NaH + H 2 O → NaOH + H 2 Reaction with carbon. Lithium is the only metal that reacts directly with carbon to give dilithium acetylide. Na and K can react with acetylene to give acetylides. 2Li + 2C → Li ...
