Solid-state solvent-free catalyzed hydrogenation: Enhancing reaction efficiency by spillover agents

- The kinetics of solid state hydrogenation is controlled by spillover mechanism.
- The hydrogenation rate scales with the spillover agent concentrations.
- Carbon nanotubes and silica fumed are efficient spillover agents.
- Carbon nanotubes type affects the hydrogenation rate.
- The amount of metallic catalyst could be minimized by using a spillover agent.
