Abstract
A photoelectric fluid field cluster catalytic method for atomic-scale deterministic processing, comprises the following steps: selecting nanoparticles with photocatalytic activity as a photocatalytic medium, and using a photoreduction method to realize the precipitation of metal nanoparticles on a surface of the photocatalytic medium, thus creating photoelectrocatalytic clusters; illuminating a coupling area between a surface to be processed of a workpiece, the photoelectrocatalytic clusters and a flexible tool with a catalytic light source, and simultaneously applying a bias voltage to a conductive tray of the workpiece; and applying a normal load to a flexible tool head and setting a rotation speed to generate a hydrodynamic pressure to drive a polishing solution to flow, thus enabling controllable removal with atomic-level precision. The disclosure utilizes the metal particles in the photoelectrocatalytic clusters to capture photogenerated electrons, thereby prolonging the lifetime of photogenerated carriers.
