Nanotip-induced electric field for electrocatalysis

The application of nanotip-induced local electric fields has been demonstrated to effectively tailor the microenvironment and electrochemical properties of catalysts, sparking significant interest in this field. Modifying the electronic structure at active sites, enhancing the concentration of electrolytes and reactants nearby the active center, and leveraging the strong proximity effect generated by the nanotip-induced local electric field have resulted in notable enhancements in electrocatalytic activity, selectivity, and durability. This review offers a comprehensive and structured overview of the latest progress in harnessing the tip effect in electrocatalysis, emphasizing the advantages of the local electric field influenced by the tip effect. Furthermore, it delves into the fundamental principles and origins of the electric field induced by the tip effect. Detailed conversations on applying these principles to enhance the electrocatalytic performance are also provided. The purpose of this review is to present researchers with a fresh concept and direction for further elevating electrocatalytic performance.
