ABSTRACT
In summary, we developed an efficient and rapid
ultrasound-assisted galvani replacement reaction method for the synthesis of
ultrathin cross-linked 2D Bi ML. Physical characterization confirms that the Bi
ML has an ultrathin thickness, high surface area and abundant detective atoms. Electrochemical
tests show that the Bi ML has excellent electrocatalytic performance for CO2RR
at a large current density, including high activity, high formate selectivity
and good stability. DFT calculations show that the defect sites present in Bi
ML change the charge density of surrounding atoms, which facilitates the
adsorption and desorption of intermediate *OCHO anyway and enhances the FEformate.
This work presents a new method for the rapid synthesis of 2D single Bi ML,
explaining the relationship between the catalytic behavior and structural
features of Bi ML.
