We plan to use facile methods including single-step aerosol-assisted self assembly process and dry nanodispersion process to fabricate high-surface-area nanostructured metal oxides for catalytic and photocatalytic reactions (e.g. carbonylation of glycerol, water splitting, etc.). The obtained materials will be characterize by using N2-isothermal sorption, TGA, HRTEM, FESEM/EDX, ICP-OES, XRD, FTIR, XAS, XPS, in-situ XRD and operando Raman as well as to determine the structure and activity from the same reality, thus facilitating the molecular understanding of the structure-activity/selectivity relationships. Therefore, for materials chemistry, not only classical scaling of geometrical features, for example, to achieve a high surface area can be useful in these entities but, a full range of quantum size related effects may occur that can be exploited to tune electrical, optical or chemical properties of a material. The joint project will organize mutual visit for discussion of the results and will be organized publication of joint papers and reports, joint seminars. Also, Taiwanese students will be subsidized to conduct in situ spectral investigation at CSIC. As a result of this project will be directed the future research efforts toward utilization of such tailored nanostructures is expected to play an important task in achieving the desired goal of cheap and efficient energy and environmental technologies.奈米金屬氧化物催化光催化Operando 拉曼Nanostructured metal oxideCatalysisPhotocatalysisOperando Raman
