In contrast to the bulk, Au nanoparticles possess unique absorption characteristics due to localized surface plasmon resonance in the visible-to-near-infrared region. Recently, Au nanoparticle-based plasmonic photocatalysts have emerged as promising visible-light photocatalysts for “solar hydrogen” production. This mini review deals with guidelines for the design of highly active plasmonic photocatalysts, highlighting the effect of a heteroepitaxial junction in Au(core)–CdS(shell) nanohybrids on their activity for water splitting, and as a photosensitizer for metal oxide electrodes to improve their performance in photoelectrochemical hydrogen generation from water.

与本体相反，Au纳米颗粒由于在可见到近红外区域中的局部表面等离振子共振而具有独特的吸收特性。最近，基于金纳米粒子的等离激元光催化剂已经成为有前途的可见光光催化剂，用于“太阳能氢”生产。本迷你评论涉及高活性等离激元光催化剂的设计指南，着重介绍了Au（核）-CdS（壳）纳米杂化物中的异质外延结对其水分解活性的影响，以及作为金属氧化物电极的光敏剂以改善它们在从水产生光电化学氢方面的性能。
