Description
Technical Field
The invention relates to a preparation method of a spin-polarized paper-based cuprous oxide-indium sulfide composite nanomaterial, and belongs to the field of preparation of inorganic semiconductor nanomaterial.
Background
The molecular formula of the cuprous oxide is Cu 2 O, which is a P-type semiconductor nano material with excellent performance, and has higher light absorption coefficient and faster carrier migration rate. The Cu 2 O has a forbidden band width of 2.172 eV, is a direct band gap semiconductor, and is widely used in the fields of photocatalytic water decomposition, chemical catalysis, solar cells, antibacterial and sterilization and the like. However, since the carrier migration distance of pure Cu 2 O is short, the photo-generated carriers are easily recombined, and thus further improvement of the photoelectric conversion efficiency thereof is limited.
Indium sulfide, with a molecular formula of In 2S3, is a semiconductor material with a narrow forbidden bandwidth, and is usually In three crystal forms of alpha-In 2S3、β-In2S3、γ-In2S3. In 2S3 has better chemical stability and wider spectral absorption range. However, it also has the disadvantage of rapid carrier recombination. At this stage, various methods have been reported for improving the photoelectric conversion efficiency of In 2S3, including changing its microscopic morphology (e.g., nanorods, nanospheres, nanotubes, nanoarms, etc.), forming a composite with carbon-based nanomaterials, or doping other metallic or non-metallic nanomaterials to regulate its energy level structure. Although the above method improves the photoelectric conversion efficiency of In 2S3 more effectively, the photoelectrochemical properties thereof are still poor.
The filter paper is used as a common base material in a basic laboratory, is composed of cotton fibers, contains abundant pore structures, and can provide abundant attachment sites for the growth of nano materials. Therefore, the filter paper is used as a growth substrate of the Cu 2 O and In 2S3 composite nano material, a built-In electric field can be built between composite material interfaces to drive interlayer carrier transmission and separation, the problem of faster carrier recombination of single-component materials is solved, and meanwhile, the three-dimensional network structure of the mutually interweaved paper fibers is favorable for supporting the transmission and transfer of substances between electrolyte and paper electrodes and accelerating catalytic reaction kinetics. In addition, by introducing magnetic metal ions into Cu 2 O and In 2S3, cu 2 O and In 2S3 can be endowed with adjustable spin polarization degree, and the orientation arrangement of photo-generated carriers is regulated and controlled by virtue of an external magnetic field, so that the internal carrier recombination of each component is inhibited. The prepared functional paper chip has great application potential in the field of high-valence metal ion degradation in photocatalytic water pollutants.
