Sandwich Structured Ru@TiO2 Composite for Efficient Photocatalytic Tetracycline Degradation
摘要
Abstract
TiO2 nanomaterials are widely used photocatalysts due to high photocatalytic activity,good chemical stability,low cost,and nontoxicity.However,its lower photon utilization efficiency is still limited by larger bandgap width and higher recombination rate between photon and hole.In this study,two-dimensional TiO2 nanosheets were synthesized via microetching,which were then inserted by ruthenium atoms to form an efficient photocatalyst Ru@TiO2 with sandwich structure.The surface morphology,electronic structure,photoelectric properties,and photo-catalytic degradation performance of tetracycline hydrochloride of Ru@TiO2 sandwich structure were investigated using different measurements.Results indicated that the material's photoresponse range extended from UV to visible-near-infrared regions,improving photon absorption and carrier separation efficiency while enhancing photocatalytic activity.Under simulated sunlight irradiation(AM 1.5 G,100 mW·cm-2)for 80 min,sandwich structured Ru@TiO2 efficient photocatalyst exhibited superior degradation performance on tetracycline hydrochloride with a degradation efficiency up to 91.91%.This work offers an effective way for the construction of efficient TiO2 based photocatalysts.关键词
