David Wei's team works to discover novel electronic and optical properties of metallic and semiconductor nanomaterials and their implications for electronics, photonics, energy, and biomedicine. A fundamental understanding of the structure-dependent localized optical properties of nanostructures with sub-10 nanometer resolution will lead to comprehensive knowledge of the surface plasmon-directed growth of novel anisotropic nanostructures, and design rules for the synthesis and fabrication of hybrid nanostructures with optimized properties for solar energy harvesting, conversion and storage, photocatalysis, and chemical and biological detection. These high impact, interdisciplinary projects combine analytical chemistry, physical chemistry, inorganic chemistry and materials science and engineering.

Plasmonic Photoelectrochemistry: In View of Hot Carriers

Advanced Materials

Yuchao Zhang, et al.


Utilizing plasmon-generated hot carriers to drive chemical reactions has emerged as a popular topic in solar photocatalysis. However, a complete description of the underlying mechanism of hot-carrier transfer in photochemical processes remains elusive, particularly for those involving hot holes. Photoelectrochemistry enables to localize hot holes on photoanodes and hot electrons on photocathodes and thus offers an approach to separately explore the hole-transfer dynamics and electron-transfer dynamics.

Cooperation of Hot Holes and Surface Adsorbates in Plasmon-Driven Anisotropic Growth of Gold Nanostars

Journal of the American Chemical Society

Wenxiao Guo, et al.


Light-driven synthesis of plasmonic metal nanostructures has garnered broad scientific interests. Although it has been widely accepted that surface plasmon resonance (SPR)-generated energetic electrons play an essential role in this photochemical process, the exact function of plasmon-generated hot holes in regulating the morphology of nanostructures has not been fully explored.

Manipulating Atomic Structures at the Au/TiO2 Interface for O2 Activation

Journal of the American Chemical Society

Jiawei Huang, et al.


The metal/oxide interface has been extensively studied due to its importance for heterogeneous catalysis. However, the exact role of interfacial atomic structures in governing catalytic processes still remains elusive. Herein, we demonstrate how the manipulation of atomic structures at the Au/TiO2 interface significantly alters the interfacial electron distribution and prompts O2 activation.
