The surface plasmon resonance (SPR) effect on noble metals to convert solar energy into chemical has attracted a lot of interest. However, the lack of highly efficient photocatalysts is still the forbidden obstacle as well as their large-scale development. Therefore, we focus on plasmon resonance enhanced electrocatalytic oxidation of liquid fuel employing photocatalysts to develop unique hollow platinum-silver (Pt-Ag) nanocrystals. The hollow Pt-Ag is formed of nanodendrites (Pt₁-Ag₁) which display a great enhancement in catalytic activity towards ethylene glycol oxidation with the mass and specific activity found to be: 7045.2 mA/mg and 14.1 mA/cm², respectively. This is due to: the SPR effect, efficient electronic distribution and synergistic properties, together with the unique hollow dendritic nanostructures. Impressively, the SPR effect also induces the optimum Pt-Ag nanocatalsyst under visible light irradiation conditions to display 1.7-fold enhancements in catalytic activity compared to that under dark conditions. In addition, 6.2 and 7.0-fold enhancements were obtained when the optimized Pt-Ag was employed as photoelectrocatalyst compared to the commercial Pt/C. Therefore, we present a unique catalyst which produces a high catalytic activity and long-term stability compared to those previously reported. More importantly, we also introduce a promising approach towards the designing of a plasmonic metal nanocatalyst with ideal nanostructures for liquid fuel oxidations.

表面贵金属的表面等离振子共振（SPR）效应将太阳能转化为化学物质引起了人们的极大兴趣。然而，缺乏高效的光催化剂仍然是其大规模开发的障碍。因此，我们专注于采用光催化剂的液体燃料的等离子体共振增强电催化氧化，以开发独特的空心铂银（Pt-Ag）纳米晶体。空心Pt-Ag由纳米树枝晶（Pt ₁ -Ag ₁）形成，纳米树枝晶对乙二醇氧化的催化活性大大增强，其质量和比活度分别为7045.2 mA / mg和14.1 mA / cm ^2。， 分别。这是由于：SPR效应，有效的电子分布和协同特性，以及独特的中空树枝状纳米结构。令人印象深刻的是，SPR效应还诱导了在可见光照射条件下的最佳Pt-Ag纳米催化体系，与黑暗条件下相比，催化活性提高了1.7倍。此外，与商用Pt / C相比，当使用优化的Pt-Ag作为光电催化剂时，获得了6.2倍和7.0倍的增强。因此，我们提出了一种独特的催化剂，与以前报道的那些催化剂相比，该催化剂具有很高的催化活性和长期稳定性。更重要的是，我们还介绍了一种有前途的方法来设计具有理想纳米结构的等离子体金属纳米催化剂，用于液体燃料氧化。
