研究了基于无定形亚化学计量氧化钨 (WO 3-x ) 基体和贵金属纳米粒子 (如银 (Ag)、金 (Au) 及其合金 (Ag/Au))的局部表面等离子体共振。 综上所述，该综述论文详细介绍了表面等离基元的产生机理，并且以等离激元增强拉曼光谱为例深入剖析了表面等离基元分子光谱的相关机制与应用。 基于此， 中国科学技术大学吴宇恩、周煌报道了一种高效的三维分级多孔ORR催化体系，通过在Pt基催化剂中引入稳定的多孔ZrO2和导电的N掺杂C，同时对Pt基催化剂的几何和电子结构进行优化，以实现催化活性和稳定性的提升。
基于此，大连理工大学化工学院梁长海教授课题组通过Au-载体界面的诱导及协同作用精准调控金属颗粒的几何结构，获得富含配位不饱和Au活性中心的缺陷型颗粒，在无碱温和条件下实现了芳香醇高效催化氧化制醛的工艺。 本文基于后纳米技术概念纳米构造学的思想，采用两步热聚合和溶剂热处理方法合成了WO x /Au-gC 3 N 4异质结构。 小 Au 纳米粒子被纳入超薄 gC 3 N 4通过机械化学预反应和两步热聚合（在 500 和 700 °C 下处理）。 本章应用DDA方法对于Au纳米球、Au纳米球壳定量的研究了它们吸收光谱中共振峰的位置和强度随2种Au纳米粒子的变化趋势，以便揭示Au纳米粒子吸收特性变化规律。
本文通过一种简单温和的湿化学方法合成了具有较好单分散性的球形金银合金纳米颗粒。 根据表征结果可知,合金颗粒的形貌尺寸均一,金和银两种金属元素分布均匀,属于一种多晶的晶体结构。
By controlling the amount of seed added, the ultrasonic exposure, and the centrifugal time, we can effectively tune the size of the particles and the localized surface plasmon resonance peak. 烯烃的环氧化反应在医药、环氧树脂和其他高附加值化学产品中具有广泛的应用价值。 出于经济和环保的考虑，设计合成以H2O2为氧化剂的新型、高效的环氧化催化剂已成为当前烯烃环氧化反应的研究重点。 然而，将合适的半导体与合适的减水潜力相结合仍然具有挑战性。 典型的Z方案体系由两个光催化剂组成，它们产生两组电荷载体，并在不同位置将水分解成H2和O2。 然而，大多数Z方案体系不能满足高效水分解反应的要求。
