  abstract  = {Surface-enhanced Raman scattering (SERS) spectroscopy has emerged in recent years as a promising and powerful technique to investigate the reaction mechanism of heterogeneous catalysis. In this work, the reduction reaction of 4-nitrothiophenol (4-NTP) to its corresponding amino derivate catalyzed by gold took place between the gold nanoshell and gold nanostar. Due to the strong binding of thiol group to the gold surface, the molecular configuration of 4-NTP was fixed with NO2 group towards outside. The direct contact of NO2 group with catalytic gold nanostars ensured the reduction reaction went smoothly, which was monitored by SERS spectroscopy. The NO2 vibration Raman band showed a unique blue-shift without any appearance of dimerization product, indicating this catalytic reaction might follow a monomolecular mechanistic pathway.
