|a In situ monitoring of reactant transformations at metal catalyst surfaces and/or interfaces, combined with the identification of intermediate species and products, is vital for elucidating catalytic processes and behaviors. We developed innovative spinous AuAg nanowires (NWs) with a bimetallic structure and dense alloy protrusions, demonstrating both catalytic activity and surface-enhanced Raman spectroscopy (SERS) capabilities, thereby facilitating in situ SERS tracking of reactions. The spinous Au@Ag NWs exhibit sharp spikes on their surface, providing a large number of catalytically active sites. They demonstrate outstanding sensitivity, signal reproducibility, and homogeneity when detecting representative dye molecules like crystal violet. Furthermore, the spinous Au@Ag NWs exhibit outstanding catalytic performance, enhancing the separation and movement of photogenerated electron-hole pairs. This research offers important insights for the design of multifunctional SERS substrates and paves the way for new opportunities in the in situ monitoring of catalytic processes
