The invention provides a Fe / Cu-BTC-BA catalyst as well as a preparation method and application thereof, and relates to the technical field of metal organic framework materials. The preparation method comprises the following steps: mixing an iron source, a copper source, trimesic acid, benzoic acid and hexadecyl trimethyl ammonium bromide with a solvent, carrying out solvothermal reaction at 120-140 DEG C for 20-28 hours, and filtering, washing and drying to obtain the target catalyst. Fe-Cu double active sites are constructed and are combined with double ligands to induce Cu < 2 + > to be converted into Cu < + >, so that the Lewis acidity and hydrogen sulfide adsorption activation capability are enhanced, the skeleton stability is improved, and meanwhile, the pore structure is optimized. The catalyst has the advantages of high specific surface area, highest sulfur capacity of 7.8%, high desulfurization rate and stable structure, and is suitable for catalytic desulfurization of sulfur-containing gas.

The application provides a low-temperature high-conductivity polyether electrolyte and a preparation method thereof. The polyether crosslinking network is formed by crosslinking polyethylene glycol monomethyl ether methacrylate and polyethylene glycol diacrylate, tri(pentafluorophenyl)borane and lithium salt are introduced to form a borane-lithium salt complex system, the molar ratio of lithium ions to borane is accurately controlled to be 1:0.02-0.20, and the acetonitrile complexing-vacuum desolventizing-in-situ polymerization curing process is used, so that the high-purity thin film electrolyte with the ion conductivity ≥1*10 ‑4 S / cm, residual acetonitrile ≤500 ppm and moisture ≤1000 ppm at low temperature is realized, technical problems that the low-temperature conduction capacity decreases when the crosslinking modulus of the traditional polyether electrolyte is improved, the processing window of the high-lithium salt system is narrow, and the interface stability of residual solvent and moisture is difficult to consider are effectively solved, and the low-temperature performance, processing stability and wide solid-state lithium battery application prospect are excellent.
