“…As is widely known, ultrasonic treatment can alter the microstructural properties of electrocatalysts. [98][99][100] Using ultrasound during the mixing procedure enhances heat and mass transfer. In the presence or absence of surface-active agents and ethanol, ultrasonic waves have been employed to synthesize monometallic or bimetallic nano-electrodes.…”

With the advancement of scientific research, the introduction of external physical methods not only adds extra freedom to the design of electro‐catalytical processes for green technologies but also effectively improves the reactivity of materials. Physical methods can adjust the intrinsic activity of materials and modulate the local environment at the solid‐liquid interface. In particular, this approach holds great promise in the field of electrocatalysis. Among them, the ultrasonic waves have shown reasonable control over the preparation of materials and the electrocatalytic process. However, the research on coupling ultrasonic waves and electrocatalysis is still early. The understanding of their mechanisms needs to be more comprehensive and deep enough. Firstly, this article extensively discusses the adhibition of the ultrasonic‐assisted preparation of metal‐based catalysts and their catalytic performance as electrocatalysts. The obtained metal‐based catalysts exhibit improved electrocatalytic performances due to their high surface area and more exposed active sites. Additionally, this article also points out some urgent unresolved issues in the synthesis of materials using ultrasonic waves and the regulation of electrocatalytic performance. Lastly, the challenges and opportunities in this field are discussed, providing new insights for improving the catalytic performance of transition metal‐based electrocatalysts.
