| titleOfInvention | Nano-ZnO loaded magnetic biochar composite photocatalyst and preparation method thereof |
| abstract | A magnetic biochar composite photocatalyst loaded with nano-ZnO and a preparation method thereof are disclosed, the first step is as follows: thermally hydrolyzing biomass under alkaline conditions to extract plant fibers, drying, performing pre-carbonization treatment, mashing, and sieving with a 10-20 mesh sieve; the second step is that: mixing the ferrous salt solution with the potassium hydroxide solution, and adding soluble zinc salt; the third step: adding the sieved plant fibers into the solution formed in the second step, uniformly mixing, adding a potassium nitrate solution, fully stirring, carrying out water bath, and continuously stirring and aging until a black gel is formed to obtain a black gel solution; the fourth step: and washing and drying the black gel solution to generate dry gel, calcining the dry gel, continuously introducing inert gas, washing and drying to obtain the nano-ZnO loaded magnetic biochar composite photocatalyst. The invention adopts the magnetic biochar as the carrier of the photocatalyst, and solves the problem that the photocatalyst is difficult to separate and recycle in the chromium-containing sewage treatment. |
