Overview

Kinetically guided approach optimizes pore architecture in nanoporous copper for surface‐enhanced Raman spectroscopy, enhancing detection.

Key Points

  • This research focuses on the kinetic fabrication of bulk nanoporous copper with enhanced plasmonic properties for improved Raman spectroscopy.
  • Fabrication of robust bulk nanoporous copper using a free‐corrosion dealloying process.
  • Systematic variation of Ti–Cu alloy composition and HF etchant concentration to achieve fine-tuning of pore sizes.
  • Conducting electrochemical Tafel analysis to study dissolution kinetics and microstructure.
  • Demonstrated pore size tuning from approximately 50 nm to 200 nm based on the precursor phase constitution.
  • Achieved an optimal pore architecture with about 150 nm pores for maximum SERS enhancement.
  • Confirmed intrinsic link between plasmonic properties and the nanoporous copper's microstructure during SERS applications.
