| titleOfInvention | High-uniformity and small-size nano titanium dioxide, nano titanium dioxide dispersion liquid, and preparation method and application thereof |
| abstract | The invention relates to high-uniformity and small-size nano titanium dioxide, a nano titanium dioxide dispersion liquid, and a preparation method and application thereof. The method comprises the following steps: s1: dissolving titanium tetrachloride in the ice water mixture, and stirring to obtain a clear light yellow clear liquid; s2: adding a surfactant into the clarified liquid obtained in the step S1, stirring and dissolving completely, then dropwise adding ammonia water at the speed of 40-80 mu L/S until the liquid is completely solidified, then adding water, stirring to form a white turbid liquid system, and then dropwise adding ammonia water until the pH of the system is 6-8; s3: standing and layering the system obtained in the step S2 to obtain white precipitate, washing, centrifuging, drying and grinding to obtain white powder; s4: and calcining the white powder obtained in the step S3 at 350-800 ℃ to obtain the nano titanium dioxide. The nano titanium dioxide prepared by the preparation method provided by the invention has the advantages of 10-40 nm in size, good dispersibility and stability, excellent photocatalytic performance, few process flows, low equipment requirements, no excessive site limitation, simplicity in operation, low cost and high raw material conversion rate. |
