摘要： The present invention combines the advantages of fabrication of semiconductor heterostructure (Ag3PO4—WO3) with plasmonic metals (Pt and Ag) with optical interference to optimize the visible light photo response of plasmonic metals deposited semiconductor (Pt—Ag/Ag3PO4—WO3) for visible light assisted H2 generation utilizing the aqueous bio-alcohols. Crystalline Ag3PO4 and WO3 nanofibers were synthesized by microwave and electrospinning methods. Three different WO3 nanofibers composition (5, 10 and 15 wt. %) were used to obtain Ag3PO4/WO3 nanocomposite heterostructures, which are effective visible light active photo catalysts. Further, a simple, enviro-friendly, and cost-effective biogenic synthesis method have been achieved using Salvia officinalis extract to decorate Pt and Ag metal nanoparticles on the surface of Ag3PO4—WO3 composites. Presence of bioactive agents in the extract are responsible for the Pt and Ag3PO4 reduction and for prevention of the Pt nanoparticles from aggregation in aqueous medium.

摘要： A photocatalytic material for efficient photocatalytic removal of a high-concentration nitrate, and a preparation method and use thereof are disclosed. The preparation method includes the following steps: step 1: preparation of a citrate-stabilized silver nanoparticle; step 2: synthesis and functionalization modification of SiO2 step 3: preparation of Ag/SiO2; and step 4: preparation of an Ag/SiO2@cTiO2 core-shell structure. The photocatalytic material prepared by the present disclosure has high reduction catalytic activity and can quickly remove a high-concentration nitrate and achieve high nitrogen selectivity. In addition, due to protection of a titanium dioxide shell, the photocatalytic material has excellent stability and can remove a high-concentration nitrate in water when the nitrate coexists with a high-concentration chloride ion.
