The application aims to provide a method for loading zinc atom clusters on the surface of ruthenium nanoparticles by breaking Zn-N bonds based on H2 thermal drive and application, and belongs to the technical field of preparation of nanometer catalytic materials; the method takes a double-limiting material containing coordination limited Zn-N4 and narrow hole limited Ru clusters as a precursor, thereby ensuring uniform dispersion and close proximity of initial active sites; H2 is used as a key inducer, active hydrogen species generated by catalytic cracking of hydrogen by ruthenium sites is used, and hydrogen overflow effect is used to realize the breaking of thermodynamically stable Zn-N bonds; high-mobility Zn atoms are obtained and finally selectively captured on the surface of Ru nanoparticles; Zn species diffuse, nucleate and grow on the surface of Ru crystals to form sub-nanometer scale Zn atom clusters through self-assembly; and the material can improve the intrinsic catalytic activity and stability of Ru-based catalysts and provide a new way for efficient energy conversion.

A container for storing a chemical fluid for manufacturing an electronic material, in which after an inspection solution charges the container and stored at 25° C. for 30 days, a sum of a concentration of particulate metal including an iron atom, a concentration of particulate metal including a copper atom, and a concentration of particulate metal including a zinc atom which are measured by a Single Particle ICP-MASS method in the inspection solution is 100 ppt or less.

The application belongs to the technical field of aqueous batteries, and particularly relates to an alkyl glycoside aqueous zinc ion battery electrolyte, a preparation method and application thereof. The electrolyte comprises a solvent water, an electrolyte and an additive; and the additive is an alkyl glycoside. The alkyl glycoside additive with double adsorption functions for zinc ions and a zinc metal (002) crystal surface is added in the electrolyte. The additive not only can break the close combination of a water sheath layer [Zn(H2O)6] 2+ ] in a traditional aqueous electrolyte and zinc ions, prevent water molecules from contacting the zinc metal, and thus relieve the hydrogen evolution corrosion reaction of the zinc metal, but also can have a higher adsorption energy for the zinc metal (002) crystal surface than for a (100) crystal surface, so as to guide the zinc ions to be more reduced and deposited on the (002) crystal surface, and the zinc atoms mainly grow horizontally on the zinc metal (002) crystal surface, and thus the generation of zinc dendrites is avoided.

The application provides an activator for a rubber vulcanization reaction and a preparation method and application thereof, and belongs to the technical field of catalysts. The activator for the rubber vulcanization reaction comprises a carrier and zinc oxide. The carrier is a nanomaterial doped with a nonmetallic element. The zinc oxide is anchored to the outer surface of the carrier. The zinc oxide is coordinated with the nonmetallic element doped on the outer surface of the carrier to form a monatomic layer in the form of fully exposed sub-nanoclusters. The zinc atoms are not overlapped and are anchored to the outer surface of the carrier in the form of dispersed fully exposed sub-nanoclusters by coordination of the zinc oxide and the nonmetallic element doped on the outer surface of the carrier, so that the zinc atoms can be fully exposed to serve as active centers and improve catalytic activity. The activator can be applied to the vulcanization reaction in the rubber field, improves the vulcanization reaction efficiency, and can reduce the zinc consumption by 70-80% due to the full exposure of the zinc atoms, thereby saving industrial energy consumption and metal resources.
