As an important clean energy, hydrogen energy has the advantages of light weight, high calorific value, and environmental protection. If hydrogen energy can be well developed and stored, it will play more and more important roles in the human production and life. Methanol steam reforming (MSR) hydrogen production technology, which has been used in industry for many years, is the best choice for methanol hydrogen production because of its high hydrogen content in reforming tail gas and mature technology. ABO3 perovskite oxide is a new type of material. Compared with other materials, due to its unique electronic structure, it has various properties such as electricity, magnetism, optics and chemistry. It have shown great application prospects in many fields. The perovskite composite oxide was synthesized by the sol-gel method. After loading copper oxide, a perovskite-supported catalytic material was obtained. The catalytic material was characterized by XRD (X-ray diffraction), BET (Brunner-Emmet-Teller), H2-TPR (H2-temperature programmed reduction) and XPS (X-ray photo- electron spectra). The effect of the structure and properties of perovskite-loaded nano-copper catalytic materials on the performance of methanol steam reforming for hydrogen production were investigated. The results showed that the catalytic activity of the perovskite-loaded nano-copper catalytic material is mainly related to the copper surface area, the catalytic and reductive properties, the oxygen lattice deficiency on the surface of the catalyst, and the interaction between the active component and the carrier. Among them, because the CuO/LaCrO3 perovskite-supported catalytic materials have the larger copper surface area, the lower reduction temperature, the more oxygen vacancies on the surface, and the stronger interaction between the active component, the catalytic activity of methanol steam reforming for hydrogen production is better than that of the CuO/LaNiO3, CuO/LaFeO3 and CuO/La2Zr2O7. When the reaction temperature was 360 ℃, the CuO/LaCrO3 perovskite catalyst did not show significant deactivation, the methanol conversion rate was 98.6%, and the hydrogen production rate was 694.9 mL•kgcat –1•s –1.
