Beschreibung
Zusammenfassung:	A silver/titanium dioxide in-situ loaded biomass material based on polydopamine modification and a preparation method therefor. The method comprises the following steps: impregnating a pretreated biomass material in a dopamine solution, adjusting a pH value to be 8-10 and performing stirring reaction to obtain a polydopamine modified biomass material; first impregnating the polydopamine modified biomass material in a titanyl sulfate solution and then performing hydrolysis reaction in an alkaline solution having the pH value of 7-10 to obtain a titanium dioxide in-situ loaded biomass material; impregnating the obtained titanium dioxide in-situ loaded biomass material in a silver nitrate solution, performing reduction reaction, and drying the material to obtain the silver/titanium dioxide in-situ loaded biomass material. The method has the advantages that the method is simple, industrialization is easily implemented, a mildew-proof effect is good, and the like. L'invention concerne un matériau de biomasse charg
