Ultrasmall copper nanoparticles were synthesized with lemongrass tea. The nanoparticles were used to catalyze the NaBH<sub>4</sub>-reduction of model compounds in solution, Eosin yellow, methylene blue, and p-nitrophenol. Catalysis kinetics were analyzed with UV-vis time-course spectroscopy. Temperature dependence was demonstrated, and relative activation energies were obtained by the construction of Arrhenius plots. Preliminary work with electrocatalysis using carbon electrode supported nanoparticles will be presented.
