报告题目：Catalytic Reactions on TiO2 and Tip-Enhanced Raman Spectroscopy

报告时间：2016年7月6日（星期三）上午10:00

报告摘要：

The catalytic activity of reducible oxides is often dominated by surface defects. Our studies have focused on how such reactive sites affect the chemical activity of the oxide, specifically TiO2, using scanning tunneling microscopy (STM). Acetone and formaldehyde are involved in many surface catalytic and photo-catalytic reactions on metal oxides. The unique methodology enables us to achieve the atomic-level understanding of the key elemental steps — adsorption, dissociation, diffusion, and coupling reaction — taking place in heterogeneous catalytic reactions.

Two-dimensional (2D) materials beyond graphene have unique mechanical, optical and electronic properties with promising applications in flexible devices, catalysis and sensing. Here we obtain nanoscale optical images by using resonant tip-enhanced Raman scattering (TERS) of MoS2. We investigate the limits of signal enhancement.
