Abstract: The present invention relates to the technical field of functional materials, and in particular to an amorphous metal oxide hollow multi-shell material and a preparation method therefor and an application thereof. The method includes the following steps: 1) performing a heating reaction on a carbon source aqueous solution, filtering, washing, and drying to obtain a carbon sphere template; 2) dispersing the carbon sphere template obtained in step 1) in a first metal salt solution, heating, adsorbing, and drying to obtain a first solid precursor; 3) dispersing the solid precursor obtained in step 2) in a second metal salt solution again, adsorbing, and drying to obtain a second solid precursor; and 4) calcinating the second solid precursor obtained in step 3) to obtain the amorphous metal oxide hollow multi-shell material. According to the present invention, a defect-controllable doping energy level is introduced into a metal oxide hollow sphere by means of a two-step enhanced adsorption method, so that efficient absorption of wave bands in a solar spectrum is achieved.

Abstract: Optical and electronic detection of chemicals, and particularly strong electron-donors, by 2H to 1T phase-based transition metal dichalcogenide (TMD) films, detection apparatus incorporating the TMD films, methods for forming the detection apparatus, and detection systems and methods based on the TMD films are provided. The detection apparatus includes a 2H phase TMD film that transitions to the 1T phase under exposure to strong electron donors. After exposure, the phase state can be determined to assess whether all or a portion of the TMD has undergone a transition from the 2H phase to the 1T phase. Following detection, TMD films in the 1T phase can be converted back to the 2H phase, resulting in a reusable chemical sensor that is selective for strong electron donors.

Abstract: To provide a lithium ion conductive crystal body having a high density and a large length and an all-solid state lithium ion secondary battery containing the lithium ion conductive crystal body. A Li5La3Ta2O12 crystal body, which is one example of the lithium ion conductive crystal body, has a relative density of 99% or more, belongs to a cubic system, has a garnet-related type structure, and has a length of 2 cm or more. The Li5La3Ta2O12 crystal body is grown by a melting method employing a Li5La3Ta2O12 polycrystal body as a raw material. With the growing method, a Li5La3Ta2O12 crystal body having a relative density of 100% can also be obtained. In addition, the all-solid state lithium ion secondary battery has a positive electrode, a negative electrode, and a solid electrolyte, in which the solid electrolyte contains the lithium ion conductive crystal body.

Abstract: A mesoporous metal oxide materials with a chiral organization; and a method for producing it, in the method a polymerizable metal oxide precursor is condensed inside the pores of chiral nematic mesoporous silica by the so-called “hard templating” method. As a specific example, mesoporous titanium dioxide is formed inside of a chiral nematic silica film templated by nanocrystalline cellulose (NCC). After removing the silica template such as by dissolving the silica in concentrated aqueous base, the resulting product is a mesoporous titania with a high surface area. These mesoporous metal oxide materials with high surface area and chiral nematic structures that lead to photonic properties may be useful for photonic applications as well as enantioselective catalysis, photocatalysis, photovoltaics, UV filters, batteries, and sensors.
