To improve the sustainability of transportation, a major goal is the replacement of
conventional petroleum-based fuels with more sustainable fuels that can be used in the …

Syngas, a mixture of CO and H 2 (CO/H 2), is a key platform for the utilization of
nonpetroleum carbon resources such as natural gas or shale gas and coal. Syngas can also …

There are many studies related on the SnO 2/SnO based solar thermochemical water
splitting cycle, however there are still no studies addressing on the detailed thermodynamic …

This article provides a comprehensive overview of the work to date on the two‑step solar
H2O and/or CO2 splitting thermochemical cycles with Zn/ZnO redox reactions to produce H2 …

Thermochemical storage of solar heat exploits the enthalpy effects of reversible chemical
reactions for the storage of solar energy. Among the possible reversible gas–solid chemical …

Solar hydrogen production via two-step water-splitting thermochemical cycle is an appealing
and completely sustainable “green” process. This paper attempts to present a review on this …

Ceria-type materials were investigated as reactive chemical intermediates, in view of solar
thermochemical hydrogen production via two-step water-splitting. Ceria/zirconia mixed …

Solar syngas production from CO2 and H2O is considered in a two-step thermochemical
cycle via Zn/ZnO redox reactions, encompassing: 1) the ZnO thermolysis to Zn and O2 using …
