The invention discloses a Pt nano-catalyst based on TS-1 molecular sieve strong metal-carrier interaction and application thereof.According to the Pt nano-catalyst based on TS-1 molecular sieve strong metal-carrier interaction and the application thereof, a two-step strategy of first oxidation and second thermal reduction is adopted, firstly, Pt and a carrier TS-1 form strong interaction, agglomeration of precious metal particles is hindered, and therefore the particle size of the precious metal catalyst is reduced, and the precious metal catalyst with the smaller particle size is prepared; the catalytic reaction activity of the noble metal catalyst is improved. In the subsequent reduction process, high-valence Pt is converted into a metal state, a Pt0 (Pt delta +) / PtOx interface structure is formed, and a new channel is provided for interface electron transfer and catalytic activity. Meanwhile, TS-1 can be induced to generate a large number of oxygen vacancies, the Lewis acid site of TS-1 is enhanced, and the strong interaction between Pt and TS-1 is enhanced. As a lithium-sulfur battery diaphragm coating material, conversion of polysulfide can be more effectively accelerated, the shuttle effect is inhibited, and the electrochemical performance of a lithium-sulfur battery is improved.

This invention relates to an MFC-A / O / A coupled wastewater treatment system, method, and application, comprising an A / O / A device and an MFC device connected in series. The A / O / A device includes an influent tank, an anaerobic tank, an aerobic tank, an anoxic tank, and a sedimentation tank connected in sequence. The MFC device includes: an anode disposed in the anaerobic tank; a cathode disposed in the aerobic tank; a resistor disposed outside the A / O / A device and connected to the anode and cathode; and a proton exchange membrane disposed between the anaerobic tank and the aerobic tank. Compared with the prior art, this invention uses enriched bacteria obtained from anaerobic and aerobic enrichment as the inoculum source for the MFC-A / O / A coupled system, which accelerates the system startup, shortens the startup time, and significantly improves the system's power generation performance.
