Efficiently reclaiming the utilization of solar light in a photocatalysis system remains very challenging. By integrating full advantage of upconversion material, plasmonic metals, and narrow bandgap semiconductors, β-NaYF₄:18%Yb³⁺ and 2%Tm³⁺@SnO₂@Ag nanoparticles (denoted as NaYF₄@SnO₂@Ag NPs) are designed and successfully synthesized as a 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 gives insight to guidance of fabricating efficient, multicomponent upconversion catalysts and proposes a potential in the field of high-efficiency environmental and energy-related applications.

镧系元素掺杂NaYF ₄ / SnO ₂ / Ag的高效UV-Vis-NIR响应上转换和等离子体增强光催化剂

在光催化系统中有效地回收利用太阳光仍然是非常具有挑战性的。通过集成的上转换材料，等离激元的金属，和窄带隙半导体，充分利用β-NaYF ₄：18％的Yb ³⁺和2％的Tm ³⁺ @SnO ₂ @Ag纳米颗粒（表示为NaYF ₄ @SnO ₂ @Ag NPS）被设计并成功合成为广谱（UV-vis-NIR）响应上转换和等离子体增强的光催化剂。已获得的NaYF ₄ @SnO ₂@Ag NPs具有宽带光吸收尺寸，优异的光催化效率和对有机染料降解的良好稳定性。NaYF ₄ @SnO ₂ @Ag NPs的增强的光催化性能可以归因于在这种核/壳结构中组成的组分的协同效应，这导致更高的光载流子产量并有利于光载流子和能量的有效转移。这项工作为制造高效，多组分上转化催化剂的指导提供了见识，并提出了在高效环境和能源相关应用领域的潜力。
