１．概要（Summary ）
Platinum is the best material for electrical contacts, particularly in the electrically reduced water. The morphology investigation and structural analysis is one of the tools to evaluate the electrode material. Previous researchers have done tremendous amount of studies in minimizing the Pt usage. Therefore, it is nontrivial to fabricate a monolayer Pt coating on a large area substrate, particularly on a 3D substrate with complex structures.

２．実験（Experimental）
Main equipment：SEM
Methods：With the aid of conductive adhesive, the sample was placed on it and investigated.

３．結果と考察（Results and Discussion）

Perhaps due to the nano size level itself, it is not successful to obtain the clear morphology of the sample. We consider to synthesize more large size of particles and then investigate in future.
