Generation and detection of single metal nanoparticles using scanning electrochemical microscopy techniques

Article Abstract:

The generation and detection of a single metal nanoparticle (MNP) on a conductive carbon support for testing as an electrocatalyst are described using electrochemical methods. The results have shown that chemisorbed Pt particles displayed a stronger adhesion on surface-modified carbon fiber electrodes (CFEs) and better mechanical stability during proton reduction than MNPs electrodeposited directly on the CFE.

Investigation of facilitated ion-transfer reactions at high driving force by scanning electrochemical microscopy

Article Abstract:

The dynamics of facilitated ion-transfer (FIT) interactions at high driving force across the water/1,2-dichloroethane (W/DCE) network is examined by scanning electrochemical microscopy (SECM). These transfers are selected as ideal models due to their significant potential range that can be controlled externally.

Electrochemical observation of a metal/insulator transition by scanning electrochemical microscopy

Article Abstract:

The novel use of the scanning electrochemical microscope to follow the compression of a monolayer of monodisperse silver thiol-capped nanoparticles on a Langmuir trough is presented. The result reveals that the transition from an insulating to conductive behavior with compression can be followed.
