ABSTRACT We suggest a new method for preparing metal electrodes based on carbon nanoelectrodes (CNEs), which are suitable application in shearforce scanning electrochemical microscopy (SECM). The as‐prepared CNEs were focused ion beam (FIB)‐processed, subsequently thermally recessed, and finally, Pt or Au electrodeposited into the cavity of recessed leading to insulator‐free with sizes around 2 µm diameter. For their as local voltammetric pH sensors, calibrated concentration range 11.6 M H + 9 OH − . As case study, we determined situ using developed microelectrode positioned close proximity an Ag‐based gas diffusion electrode (GDE) was operated oxygen reduction reaction (ORR). could observe shift ox peak Δ E = −700 mV, is exceeding previous observations at GDEs by far. This novel type will pave way perform SECM even higher spatial resolution due spearhead shape.
