Abstract

To effectively produce solar hydrogen through the two step water decomposition cycle, a CeO₂-NiO (Ce: Ni = 9:1) solid solution was synthesized by the coprecipitation method. CeO₂-NiO was coated on ceramic (Al₂O₃) substrate and sintered at 90-150°C inorganic adhesive. In order to quickly increase the reaction surface area emitted by O₂, laser material treatment was used, and the delicate laser texture pattern was confirmed by laser treatment on CeO2-NiO. In the periodic two step water decomposition process at 1200 – 800°C, the O₂ gas produced in the O₂ emission reaction with CeO₂-NiO substrate with suitable laser treatment is almost twice that of the untreated substrate.
