AI Technical Summary
Existing technologies are insufficient for the high-precision detection of the physical properties and catalytic activity of individual nanocatalysts, especially for small-sized or low-activity nanocatalysts, and suffer from high background noise and low signal-to-noise ratio.
By employing a nano-gap electrode based on the quantum tunneling effect, combined with a functionalized layer and gate potential modulation, in-situ detection of single-particle nanocatalysts is achieved, and their physical properties and catalytic reaction information are obtained through tunneling current.
It achieves high-sensitivity detection of small-sized and low-activity nanocatalysts, improves the signal-to-noise ratio, ensures the fidelity of single-particle events, and simultaneously acquires multi-dimensional information about nanocatalysts.
