The heterogeneous catalytic performance is largely dependent on the catalyst nanostructures or, in another word, processing technologies, in addition to the intrinsic physical and chemical properties of the constitutive components. Compared to the amorphous framework of mesoporous silica, mesoporous metal oxides synthesized by a hard templatereplicating method usually have a crystallized structure and exhibit excellent catalytic activities, as reported in many documents. The loading or dispersion of catalytically active guest species into the host mesopore network results in mesostructured composites of a crystallized framework and highly dispersed catalytic species in its mesopore network. Mesoporous inorganic oxide materials, in the form of either powder or thin film, with high surface areas, ordered pore structures, finely tunable pore sizes, and flexible wallcompositions have been investigated widely of their chemical synthesis and potential applications in catalysis, adsorption, chemical sensing, electrochemistry, biomedical areas, and so on.

A preparation method of the light absorption layer of a copper-indium-gallium-sulfur-selenium film solar cell is provided. The method employs a non-vacuum liquid-phase chemical technique, which comprises following steps: forming source solution containing copper, indium, gallium, sulfur and selenium; using the solution to form a precursor film on a substrate by a non-vacuum liquid-phase process; drying and annealing the precursor film. Thus, a compound film of copper-indium-gallium-sulfur-selenium is gained.

A lithium lanthanum zirconium oxide (LLZO) having a garnet crystal structure contains fluorine in an amount up to 40 mol %. The fluorine, which may be in the form of a lithium compound such as lithium fluoride, may act as a sintering aid and promote formation of the cubic garnet phase. The sintered oxide may be a dense ceramic that includes a plurality of distributed closed pores. Solid electrolyte membranes comprising the oxide can have an ionic conductivity of at least 110

A cathode current collector for a lithium-air battery includes a carbon-free, conductive, porous matrix. The matrix may include a metal boride, a metal carbide, a metal nitride, a metal oxide and/or a metal halide. Example matrix materials are antimony-doped tin oxide and titanium oxide. A carbon-free cathode exhibits improved mechanical and electrochemical properties including improved cycle life relative to conventional carbon-containing porous cathode current collectors.
