Biomimetic synthesis of Ag2CrO4 quasi-nanorods and nanowires by emulsion liquid membranes

Semiconductor Ag2CrO4 quasi-nanorods and nanowires have been successfully prepared through novel emulsion liquid membrane technology. The membrane phase in this system consists of Span-80 as the surfactant, N7301 as the carrier (or free carrier), and kerosene as the solvent. The internal aqueous phase is 0.1 M AgNO3 and the external aqueous phase is 0.1 M K2Cr2O7. Under the conditions of Roi = 2.0, Rew = 0.5, [Span-80] = 6% (v/v), and room temperature, Ag2CrO4 quasi-nanorods with diameters of 180-300 nm and lengths of up to 2300 nm, or nanowires with diameters of 15-25 nm and lengths of up to 1000 nm, were obtained in the presence or absence of 5% (v/v) N7301, respectively. X-Ray diffraction and transmission electron microscopy were used to characterize the structure and morphology of the Ag2CrO4 quasi-nanorods and nanowires. In addition, the photoluminescence spectrum showed strong emissions.
