Description	The synthesis of Cu nanoparticles (NPs) via the reduction of Cu ions with sodium borohydride in the presence of sodium polyacrylate is presented. The final Cu nanocrystals having 14 nm in diameter were generated via the aggregation and coalescence of the primarily formed ultrasmall particles (approx.3 nm). Addition of sodium sulphite to the dispersions provided the protection of the Cu NPs against oxidation. On the other hand, the controlled aeration of the Cu NPs resulted in their transformation to Cu2O nanocubes with the average size of 18 nm. Both Cu NPs and Cu2O nanocubes can effectively catalyze reduction of 4-nitrophenol by sodium borohydride in aqueous solution.
