The Enhanced Photo-Catalytic Properties of ZnO Under the Synergistic Effect of CaCO3

At present, the problem of environmental pollution is becoming increasingly serious. It is urgent to develop efficient catalysts to solve these problems. To obtain the functional characteristics of CaCO 3 and promote its application in coatings and photo-catalysis, ZnO/CaCO 3 particles are prepared by the solution co-precipitation method under the mediate of sodium dodecyl sulfate (SDS) through corresponding strategies. The structures and morphologies of samples are characterized by XRD, FT-IR, SEM, and TEM, respectively. Besides that, the photo-catalytic property of the desired product is also evaluated. The results indicate that SDS helps to induce the formation of porous structure. Through co-precipitation, ZnO particles uniformly load on porous calcium carbonate. ZnO/CaCO 3 particles are endowed with low-cost property and high catalytic performance under the synergistic effect of photo-catalytic properties and absorption abilities. This work established a simple way to produce the composite catalysts with low price and high photo-catalytic activity.
