英文摘要	hexagonal beta-co(oh)(2) nanosheets with edge length of 50 nm and thickness of 10 nm were hydrothermally synthesized with the aid of triethylamine. upon calcination at 350 a degrees c in air, the beta-co(oh)(2) nanosheets was converted into co3o4 nanosheets with a similar dimension. structural analyses during the calcination process identified that the beta-co(oh)(2) precursor was initially dehydrated to hcoo2 and subsequently transferred into co3o4. when being applied to catalyze co oxidation at room temperature, the co3o4 nanosheets exhibited a higher activity than the conventional spherical nanoparticles. this was perhaps related to the partial exposure of the {11} planes over the co3o4 nanosheets. the porous structure generated during the calcination process also provided significant amounts of surface defects, which might contribute to the enhanced catalytic activity as well.
