Controlling the Size and Pattern Pitch of Ni(OH)2 Nanoclusters Using Dip-Pen Nanolithography to Improve Water Oxidation

Molecules. 2020 Jun 26;25(12):2937. doi: 10.3390/molecules25122937.


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.

Keywords: Ni(OH)2; alternative energy; dip-pen nanolithography; meta-chemical surface; water-splitting process.
