Preparation of silver-nanoparticle-loaded C60-ethylenediamine adduct microparticles and their application to photoelectric conversion

We report here new types of suprastructure products consisting of C-60-ethylenediamine microparticles and silver nanoparticles that were loaded onto the surfaces of the microparticles by electrostatic adsorption. The suprastructure products could be deposited on the surface of an indium tin oxide electrode by electrostatic deposition. These modified electrodes generated cathodic photocurrents in the presence of ascorbic acid and oxygen. The photocurrent generation behavior implies an ensemble of the electron-transfer processes of silver-nanoparticle-mediated electron transfer acting in the cathodic direction and plasmon-induced charge separation acting in the anodic direction.

Automated summary

This study introduces new suprastructure products composed of C-60-ethylenediamine microparticles and silver nanoparticles, loaded onto surfaces of microparticles through electrostatic adsorption. These products can be deposited onto indium tin oxide electrodes by electrostatic deposition, generating cathodic photocurrents in the presence of ascorbic acid and oxygen. The photocurrent generation suggests a combination of silver-nanoparticle-mediated electron transfer in the cathodic direction and plasmon-induced charge separation in the anodic direction.
