Controlling the Size and Pattern Pitch of Ni(OH)2 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.

“…It can be seen that the synthesized materials seem similar to a cluster of nanoparticles. The chia extract is worked as a capping agent for the particles, and they are probably attached by the hydroxyl groups in the molecules, so it gives the appearance of a nanocluster molecule [ 45 , 46 , 47 ].…”

“…While the common meta-surfaces enable a wide range of unique optical behaviors that are not commonly found in nature, [53] MCSs exhibit unique chemical properties that, though also present in the material's bulk form, are augmented when patterned. In addition, while most meta-surfaces are based on semiconductor materials and metals, MCSs can be manufactured from liquid inks, including salt solutions, polymers, and/or proteins, as shown in this work and in our recent related work, [41] in which the MCS was used as the working electrode in the sensor device.…”

“…It allows maximum participation of active material sites in the reaction. [41][42][43] The preparation processes of most nanostructures, however, are complex, and they require extreme conditions and multistep syntheses. [44] Countless studies have therefore been done to simplify the processes without making them exorbitantly expensive.…”

“…The use of supporting materials allows improving both the catalytic properties and the stability under harsh reaction conditions. In this Issue, three innovative and original investigations dealing with vanadium-containing faujasite zeolite [ 10 ], TiO 2 thin-films [ 11 ] and Ni(OH) 2 nanoclusters [ 12 ] are described.…”
