The invention belongs to the field of photocatalysis, and relates to an indium oxyhydroxide/acid modified attapulgite (InOOH/H-ATP) photocatalytic composite material and a preparation method and application thereof. The preparation method includes: ultrasonically dissolving the acidified attapulgite and indium nitrate in a mixed solution of distilled water and N,N-dimethylformamide; then transferring it to a microwave reaction kettle, and performing a microwave solvothermal reaction for a certain period of time; waiting for cooling After reaching room temperature, the reaction product was collected by centrifugation, washed with water and alcohol, vacuum dried, and ground; finally, it was transferred to a tube furnace for calcination to obtain the InOOH/H-ATP photocatalytic composite material. The InOOH/H-ATP photocatalytic composite material prepared by the invention has uniform loading, good dispersibility, abundant active sites, large specific surface area, and rich oxygen vacancies, achieves visible light response, and effectively suppresses photogenerated carriers. The composite enhances the performance of the photocatalyst and has an excellent effect on the photocatalytic reduction of carbon dioxide to methanol. |
