Gold catalyst recycling study in base-free glucose oxidation reaction

This work is devoted to the study of viability of immobilized gold colloids on carbon as catalysts for the base-free glucose oxidation reaction with a special emphasis made on catalysts’ recycling, operational life and possible routes for deactivation/reactivation under batch conditions. The observe...
