This application discloses a nano-tetragonal barium titanate and its process-enhanced continuous preparation method, belonging to the field of barium titanate preparation technology. The process-enhanced continuous preparation method for nano-tetragonal barium titanate includes the following steps: preparing a circulating mother liquor, a titanium tetrachloride acid hydrolysate, a barium chloride solution, and an ammonia solution; adding the titanium tetrachloride acid hydrolysate dropwise to the barium chloride solution to obtain a titanium-barium mixture; passing the titanium-barium mixture, the circulating mother liquor, and the ammonia solution into a microdroplet process-enhanced device for mixing and reaction; after heat preservation and aging, and solid-liquid separation, obtaining a mixed precipitate and a first filtrate; dissolving the mixed precipitate in a solvent, filtering to obtain barium oxalate tetrahydrate and a second filtrate; calcining the barium oxalate tetrahydrate to obtain nano-sized tetragonal barium titanate powder. By employing a microdroplet process-enhanced method, the titanium-barium mixture and the ammonia solution are dispersed into microdroplets smaller than 10 μm, enhancing the degree of material mixing, improving the mass transfer rate, and obtaining nano-barium titanate with small particle size and high purity.

This invention provides a method and application for in-situ construction of barium titanate piezoelectric nanozymes based on mesoporous silica. Mesoporous silica (MSNs) is used as a carrier, titanium acetylacetonate as the titanium source, barium chloride as the barium source, and ferric chloride hexahydrate as the iron source. After stirring for 24 h and then gradient calcination for 6 h, iron-doped barium titanate piezoelectric nanozymes grown in situ within the pores of MSNs are synthesized. The prepared material exhibits piezoelectric catalytic activity, capable of converting endogenous H2O in tumor cells into hydroxyl radicals (•OH) and O2 into superoxide anions (•O2) under ultrasonic stimulation. ‑ It also possesses peroxidase-like (POD) and superoxide dismutase-like (SOD) activities, and can utilize SOD-like activity to convert •O2 ‑ The process involves converting the generated H2O2 into H2O2, alleviating the H2O2 deficiency within the tumor microenvironment. Then, utilizing POD-like activity, the generated H2O2 and endogenous tumor-derived H2O2 are converted into •OH, achieving a piezoelectric catalysis and enzyme cascade reaction to further increase the •OH level, efficiently killing tumor cells and inducing tumor cell death. This strategy allows for the in-situ development of iron-doped barium titanate piezoelectric nanozymes that simultaneously achieve sonodynamic catalytic therapeutic performance and enzyme catalytic therapeutic performance within the channels of MSNs.
