Abstract
We use dip-pen nanolithography to accurately pattern Ni(OH) 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.
摘要
我们使用蘸笔纳米光刻技术在具有超大表面积的化学计量表面上精确图案化 Ni(OH)纳米团簇。通过控制纳米团簇之间的距离，可以控制析氧反应电流和过电势，从而在使用微量催化剂的情况下提高水分解过程的效率。
