Abstract
Efficiently reclaiming the utilization of solar light in the photocatalysis system remains very challenging. Integrating full advantage of upconversion material, plasmonic metal and narrow bandgap semiconductor, β-NaYF4:18%Yb3+, 2%Tm3+@SnO2@Ag nanoparticles (denoted as NaYF4@SnO2@Ag NPs) are designed and successfully synthesized as wide-spectral (UV-Vis-NIR) responsive upconversion and plasmonic enhanced photocatalyst. The as-obtained NaYF4@SnO2@Ag NPs present broadband optical absorption dimension, excellent photocatalytic efficiency and good stability for the degradation of organic dyes. The enhanced photocatalytic performance of NaYF4@SnO2@Ag NPs can be attributed to the synergistic effects of the components composed in this core/shell architecture that result in higher photocarriers yield and favor the efficient transfer of photocarriers and energy. This work will give insight guidance of fabricating efficient, multi-component upconversion catalysts, and propose the potential in the field of high-effi...
