Summary:We demonstrate a promising method to fabricate highly adhesive silver nanoparticle coating on glass carbon electrode with good dispersity by using gas phase cluster beam deposition. The fabricated nanoparticles have clean surface and show enhanced electrocatalytic activity toward the reduction of H2O2 with a considerably decreased overpotential. A nonenzyme sensing platform for stable detection of H2O2 with a very rapid response time (less than 1s), high sensitivity (63μA/mM) as well as a low detection limit (1.3μM) is realized from the silver nanoparticle based electrode with a optimized nanoparticle coverage.
