Preparation and Surface Activity of Single‐Crystalline NiO(111) Nanosheets with Hexagonal Holes: A Semiconductor Nanospanner

Abstract

Semiconductor single crystalline NiO nanosheets with well-defined hexagonal holes having the appearance of a nanometer-scale spanner are prepared via an efficient wet chemical route. The main surfaces of the NiO nanosheets are (111) facets and the sizes of both the sheets and the holes can be controlled. The NiO(111) nanosheets with hexagonal holes showed unusual activity for low temperature methanol decomposition.
