This invention discloses a direct repair and regeneration method for waste lithium iron phosphate cathodes based on a two-electron lithiation reagent, comprising the following steps: (1) disassembling the recycled waste lithium iron phosphate battery after complete discharge, separating and collecting the cathode active material; (2) adding an aromatic ketone dilithium reagent to the cathode active material, stirring and reacting for 1-4 hours, then centrifuging, washing, and drying to obtain a lithified regenerated lithium iron phosphate cathode; wherein: the molar ratio of lithium in the aromatic ketone dilithium reagent to the molar ratio of lithium missing in the cathode active material is ≥1; the aromatic ketone dilithium reagent is composed of aromatic ketone dilithium and an organic solvent; the molar ratio of aromatic ketone molecules to lithium in the aromatic ketone dilithium is 1:2. This invention can achieve twice the lithiation efficiency with the same amount of aromatic chemical reagent consumption, which is beneficial to reducing the material input in the repair and regeneration process. Moreover, the electrochemical performance of the regenerated layered lithium iron phosphate cathode material obtained by this invention is comparable to that of commercial lithium iron phosphate cathodes.

This invention discloses a hydrogen sensing thin film and a room temperature sensor, belonging to the field of semiconductor gas-sensitive materials and sensor technology. The hydrogen sensing thin film is composed of tungsten oxide (WO3) and highly dispersed Pt-Pd-Ni-Co-Cu-Fe hexa-element high-entropy nano-alloy particles. The sensor includes a SiO2 / Si substrate, interdigitated electrodes disposed on the substrate, and a sensitive thin film covering the surfaces of the electrodes and the substrate. The fabrication method of this invention employs a three-target synergistic magnetron sputtering process, utilizing a high-power pulsed magnetron sputtering (HiPIMS) power supply to drive a pure W target and a strongly magnetic Fe-Co-Ni alloy target respectively, while simultaneously using a DC power supply to drive a non-magnetic Pt-Pd-Cu alloy target. By effectively controlling the oxygen content within the thin film through oxygen flow rate regulation and reactive magnetron sputtering, and based on the phase formation process driven by differences in oxyphilic behavior and high mixing entropy, the phase type and size distribution within the film are controlled to form a controllable tungsten oxide + nano-high-entropy alloy dual-phase structure. Furthermore, a gradient coupling interface with oxygen-rich vacancies and strong metal-support interactions is constructed between the two phases, significantly reducing the potential barrier for hydrogen atom spillover. This hydrogen sensing thin film achieves high sensitivity operation at room temperature, shortened response time, and exhibits excellent resistance to CO poisoning and long-term cycling stability.

This invention belongs to the field of cosmetic raw material preparation technology, specifically relating to a method for decolorizing Xinjiang erythromycin, its products, and applications. The method includes: raw material pretreatment: pulverizing Xinjiang erythromycin and processing it using high-pressure instantaneous explosion technology; extraction: extracting the pretreated material with an ethanol-water solution, and obtaining a crude extract of Xinjiang erythromycin after solid-liquid separation; activated carbon decolorization: adding ethanol to the crude extract and mixing evenly, then adding activated carbon for decolorization treatment, followed by solid-liquid separation after decolorization; resin purification: loading the supernatant obtained after decolorization onto a resin column, performing gradient elution, collecting the ethanol eluent rich in phenolic acids, concentrating, and drying. This invention achieves an excellent balance between efficient decolorization and retention of highly active ingredients. It can strongly adsorb and remove dark pigments while significantly reducing the adsorption loss of the target phenolic acids.
