Abstract:Hydrogen can be produced by direct or single‐step splitting of water. The Gibbs free energy change for direct thermochemical water splitting is zero at about 4300 K at 1 bar. However, in practice, direct thermochemical splitting of water poses challenging high‐temperature materials and product separation issues, among others. One way to lower the extremely high temperatures required for direct splitting of water and mitigate gas separation issues is the use of multistep cycles. To date, more than 350 thermoche… Show more
“…A thermochemical water splitting or thermochemical cycle is a process that involves the dissociation of the water molecule into hydrogen and oxygen through a repeated series of chemical reactions. 41 This process is not catalyst-dependent, and it only uses thermal energy. The thermochemical cycle driven only by thermal energy is called the pure thermochemical cycle.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
