Background:

• Electroless metal deposition typically involves multiple metal ions.
• Developing efficient methods for single-element metal deposition on various substrates is crucial for advanced material applications.

Purpose of the Study:

• To report a versatile single-element metal deposition procedure.
• To demonstrate its application in catalysis, electromagnetic shielding, and electroadhesion.

Main Methods:

• Metal ions (e.g., Pd2+) were anchored onto a polycarbonate membrane and reduced to nanoparticles.
• The nanoparticle-modified membrane was used as a catalyst in a plating bath for further metal deposition.
• Nickel was deposited on cotton, and palladium was coated on polymers for specific applications.

Main Results:

• Palladium-nanoparticle-catalyzed deposition formed aligned palladium tubes, achieving 100% conversion of p-nitrophenol to p-aminophenol in 5 minutes.
• Nickel-coated cotton exhibited -60 dB electromagnetic interference shielding.
• Palladium-coated polymers demonstrated effective electroadhesion of gels.

Conclusions:

• The single-element metal deposition technique is versatile and efficient.
• The developed materials show promise in catalysis, electromagnetic shielding, and electroadhesion applications.
