Methods of electrochemical deposition

A method of electrochemical deposition of a textured nanoparticle, the method comprising:

• providing an alkaline solution of hydroxide ions;
• immersing a metallic material precursor into the alkaline solution to form an electrochemical bath;
• controlling a molar ratio of a concentration of hydroxide ions to a concentration of the metallic material precursor in the electrochemical bath to selectively adjust electrochemical deposition of the metallic material;
• and
• forming textured nanoparticles in the electrochemical bath, forming the textured nanoparticles comprising an electroless deposition wherein all electrons for the electroless deposition come from the hydroxide ions, the hydroxide ions acting as the reducing agent for the electroless deposition.

A method of electrochemical deposition of a metallic material onto a nanoparticle, the method comprising:

• providing an alkaline solution of hydroxide ions;
• immersing a metallic material precursor and the nanoparticle into the alkaline solution to form an electrochemical bath;
• and
• depositing a textured layer of the metallic material onto the nanoparticle, depositing the textured layer of the metallic material onto the nanoparticle comprising an electroless deposition wherein all electrons for the electroless deposition come from the hydroxide ions, the hydroxide ions acting as the reducing agent for the electroless deposition.
