AB  - Operando monitoring of catalytic reaction kinetics plays a key role in 
      investigating the reaction pathways and revealing the reaction mechanisms. 
      Surface-enhanced Raman scattering (SERS) has been demonstrated as an innovative 
      tool in tracking molecular dynamics in heterogeneous reactions. However, the SERS 
      performance of most catalytic metals is inadequate. In this work, we propose 
      hybridized VSe(2-x) O (x) @Pd sensors to track the molecular dynamics in 
      Pd-catalyzed reactions. Benefiting from metal-support interactions (MSI), the 
      VSe(2-x) O (x) @Pd realizes strong charge transfer and enriched density of states 
      near the Fermi level, thereby strongly intensifying the photoinduced charge 
      transfer (PICT) to the adsorbed molecules and consequently enhancing the SERS 
      signals. The excellent SERS performance of the VSe(2-x) O (x) @Pd offers the 
      possibility for self-monitoring the Pd-catalyzed reaction. Taking the 
      Suzuki-Miyaura coupling reaction as an example, operando investigations of 
      Pd-catalyzed reactions were demonstrated on the VSe(2-x) O (x) @Pd, and the 
      contributions from PICT resonance were illustrated by wavelength-dependent 
      studies. Our work demonstrates the feasibility of improved SERS performance of 
      catalytic metals by modulating the MSI and offers a valid means to investigate 
      the mechanisms of Pd-catalyzed reactions based on VSe(2-x) O (x) @Pd sensors.
