摘要：
A two-step thermochemical cycle for splitting CO2 and processing into solar fuels via ZnO/Zn redox reactions is considered. The first, solar step is the endothermic dissociation of ZnO to Zn and O-2. The second, non-solar step is the exothermic reduction of CO2 with Zn to CO and ZnO; the latter is recycled to the solar step. The thermodynamics and kinetics of the pertinent reactions are examined and the reactor technology for both steps of the cycle is described and an outlook for the future is provided.
