PURPOSE: A manufacturing method of the nanodendrite is provided to improve activity of an electric catalyst to ORR(Oxygen Reduction Reaction) by using Lf-PtND(Ligand-free Pt(Platinum)-on- Au(Gold) Nanodendrite. CONSTITUTION: A manufacturing method of the nano dendrite is as follows. The aqueous suspension includes a nanorattle structure. The nano nanorattle structure comprises a hollow porous silica nanoshells and nano crystals entrapped in a hollow portion. Platinum salt is reacted with the reducing agent in the aqueous suspension to obtain platinum nano dendrite coated to the porous silica shell. The hollow porous silica nanoshells are removed from platinum nano dendrite [Lf-PtND coated with porous silica nanoshells.
