The Front Cover illustrates the versatility of scanning electrochemical microscopy (SECM) as a powerful tool for probing electrocatalytic surfaces. The Review by J. S. Barroso-Martínez and M. Escudero-Escribano (DOI: 10.1002/cctc.202500352) highlights the integration of SECM as an in-situ technique and its growing role in the mechanistic study of electrocatalytic reactions, offering new insights into local activity at the electrochemical interface.
