The invention discloses an annealing technology of anchor chain steel, which comprises the following steps: putting the anchor chain steel into a cleaning solution for cleaning, then washing with water, and drying to obtain the cleaned anchor chain steel; the anchor chain steel is subjected to heat treatment, the temperature is increased to 300-400 DEG C firstly, heat preservation is conducted, the temperature is increased to 550-750 DEG C for the second time, heat preservation is conducted, the temperature is increased to 900-950 DEG C again, heat preservation is conducted, quenching is conducted to the room temperature through saline water, the temperature is increased to 300-400 DEG C through tempering, heat preservation is conducted, the temperature is increased to 500-600 DEG C through secondary tempering, heat preservation and water cooling are conducted, and the anchor chain steel subjected to heat treatment is obtained; the cleaning solution in the step S1 comprises the following raw materials in parts by weight: 20-35 parts of sodium hydroxide, 5-9 parts of diethylene triamine pentaacetic acid, 1-3 parts of sodium citrate, 1-5 parts of sodium gluconate, 6-12 parts of alkyl ethoxy polyglycosides, 11-18 parts of a compound and 150-200 parts of water, and the compound is formed by compounding sophorolipid, rhamnolipid and modified diatomite. The technical problem that anchor chain steel is low in quality is solved.

The application of binaphthyl Salen cobalt molecular catalyst modified BiVO4 photoanode belongs to the field of photoelectrocatalysis technology and organic synthesis cross. BiOI film is deposited on FTO conductive glass by electrochemical deposition method, and then is converted into BiVO4 photoanode substrate by calcination; 3-hydroxy substituted binaphthyl Salen cobalt molecular catalyst CoL is synthesized; CoL is loaded on the surface of BiVO4 by cyclic voltammetry electrodeposition to obtain a hybrid photoanode. The photoanode is applied to the photoelectrocatalytic olefin epoxidation reaction, water is used as oxygen source, and acetone-water is used as electrolyte. The strong interface coupling between the catalyst and BiVO4 is strengthened by the electrodeposition of the molecular catalyst strategy, and the interface charge transport efficiency, reaction conversion rate and selectivity are improved. The conversion rate of styrene reaches 99%, the selectivity of epoxide reaches more than 90%, and the stability is excellent. The application provides a new way for green and efficient synthesis of epoxide, and has wide application prospect.
