pH dependent ZnO nanostructures synthesized by hydrothermal approach and surface sensitivity of their photoelectrochemical behavior

Popis výsledku v původním jazyce

Nanoparticulate ZnO materials were fabricated using microwave assisted hydrothermal synthesis from mixture of zincnacetate and ammonia at variable pH. The particle size and shape of resulting materials changes with the pH of precursornsolution. The obtained nanoparticulate ZnO are of single phase nature with particle size ranging between 100 andn3000 nm, and are photoelectrochemically active in water oxidation upon UV illumination. Their photoelectrochemicalnactivity, depends primarily on the ZnO particle surface orientation which changes with the particle size. The highestnphotoelectrochemical activity results from simultaneous presence of {0− 110} and {− 2110} oriented faces. The presencenof {0001} oriented faces apparently suppresses the photoelectrochemical activity. The results indicate that the photoelectrochemicalnactivity of ZnO is mainly related to a presence of {0−110} oriented surface.
