Strong interface contact between NaYF4∶Yb,Er and CdS promoting photocatalytic hydrogen evolution of NaYF4∶Yb,Er/CdS composites
文献摘要：
To acquire efficient photocatalysts,it is necessary to make effective use of visible light/Near Infrared(NIR)light,which takes up a large percentage of sunlight.Integrating upconversion materials with visible light active photocatalysts has attracted much attention in this regard.The interface contact between upcon-version material and photocatalyst has potential influence on the properties and thus the performance of the system.In this work,NaYF4∶Yb,Er/CdS composites of the upconversion material NaYF4∶Yb,Er nanorods and CdS nanoparticles were synthesized by ion adsorption/precipitation process and were then annealed in an argon atmosphere at different temperatures to modulate the microstructures.The annealing pro-cess endows the crystal transformation of cubic CdS with low crystallinity to hexagonal CdS with high crystallinity and,importantly,good interface contact between NaYF4∶Yb,Er and CdS.Consequently,the hy-drogen evolution activity greatly increases from 171 to 2539 μmol h-1 g-1 under the light irradiation ofλ＞400 nm,and from 0 to 19 μmol h-1 g-1 under the light irradiation of λ＞600 nm.This work might provide a useful reference for the rational design of promising photocatalyst involving upconversion ma-terials.
