Morphological transformation of ultrathin gold nanosheets to rounded nanotapes in the photomediated reduction process
Photoreduction of AuCl4- ions in the presence of o-phthalaldehyde (o-PA) in water provides ultrathin gold nanosheets which show surprising morphological changes to saw-edged nanosheets, multipored sheets, and rounded nanotapes depending on the reaction temperature.
