The article discusses the utilization of metal oxide-based two-step solar-driven thermochemical water splitting technology to produce renewable hydrogen fuel. One of the challenges faced is achieving high redox kinetics and reducing the reaction temperature. The CeO2-ZrO2 oxygen carrier system is highlighted for its stability, quick kinetics, and redox cyclability. However, the reduction effect of cerium-zirconium oxide is deemed relatively low, necessitating improvement in reactivity. To address this, nickel doping was explored, leading to the preparation of different nickel-loaded oxygen carriers. The study evaluated the redox properties of these carriers in a fixed bed reactor and conducted various characterizations. It was found that the lattice oxygen in 5Ni/Ce0.8Zr0.2O2 exhibited excellent selectivity for CH4 partial oxidation within the temperature range of 880-925°C. Moreover, the 5 wt% nickel loading ratio showed the best reactivity performance. Following 60 redox cycles, the 5Ni/Ce0.8Zr0.2O2 oxygen carrier displayed significant robustness, maintaining its redox activity. The research underscores the potential of CeO2-ZrO2 with nickel doping for enhancing hydrogen production efficiency, demonstrating both stability and regenerability in the process.
