Controlling the Size and Pattern Pitch of Ni(OH)<sub>2</sub> Nanoclusters Using Dip-Pen Nanolithography to Improve Water Oxidation
Abstract
We use dip-pen nanolithography to accurately pattern Ni(OH)2 nanoclusters on a metachemical surface with an exceptionally large surface area. The distance between the nanoclusters can be manipulated to control the oxygen-evolution reaction current and overpotential, thereby improving the efficiency of the water-splitting process while using minute amounts of the catalyst.
