Abstract

The invention discloses a golf ball-shaped Ag / TiO 2 Composite porous microsphere and preparation method thereof, characterized in that the Ag / TiO 2 The composite porous microsphere has the shape of a golf ball. The preparation method uses cheap titanium potassium oxalate and silver nitrate as raw materials, and obtains Ag / TiO by spray drying technology. 2 Precursor microspheres, golf-like Ag / TiO obtained by washing after calcination 2 Composite porous microspheres to realize Ag and TiO 2 The preparation and compounding are completed simultaneously. The invention has the advantages that the used precursors are cheap titanium potassium oxalate and Ag, the cost is low, the spray drying technique is simple, and large-scale continuous production is possible. The golf ball-shaped Ag / TiO 2 Composite microspheres and their preparation methods are of great significance for the development of new photocatalytic materials.

Description

Technical field [0001] The present invention belongs to the preparation of inorganic functional materials, involving an AG / TIO 2 The preparation method of composite microspheres, specifically, involving a golf ball shape Ag / TiO 2 Composite porous microspheres and preparation methods thereof. Background technique [0002] TiO 2 Green, environmentally friendly, cheap, structure stable, has excellent photocatalytic performance, but due to its width (3.2 eV), the spectral response range is narrow, only in the ultraviolet light region, so TiO 2 As a problem, there is a low energy utilization rate of the photocatalytic material; in addition, TiO 2 Light electron-hole is easy to composite, and photocatalytic efficiency needs to be improved. Put AG and TIO 2 Composite, improve TiO 2 The photocatalyst absorption of visible light, inhibits the composite of optical electron-hole pair, improves light quantum efficiency, and improves the stability of the photocatalytic material. AG / TIO ...
