摘要利用微波辅助醇还原法在介孔结构的SBA-15中合成了不同颜色的银纳米粒子。由于局部表面等离子体共振，电荷密度部分地定位在这些Ag纳米颗粒的表面上。与通过热处理获得的Ag NP相比，这种电荷定位导致它们在可见光照射下具有增强的催化活性。
Abstract Silver nanoparticles (Ag NPs) of various colors were synthesized within the mesopore structure of SBA‐15 by using microwave‐assisted alcohol reduction. The charge density is partially localized on the surface of these Ag NPs owing to localized surface plasmon resonance. This charge localization results in them having enhanced catalytic activity under visible light irradiation compared to Ag NPs obtained by thermal processes.
