Comparative linear sweep voltammograms (LSV) (A) using 3DE compared to EPPGE, GCE, BDDE and platinum showing the onset of the HER. Stability studies of the 3DEs (B) using LSV for the initial, 10^th, 100^th and 1000^th scans. Scan rate: 25 mV s⁻¹ (vs. SCE). Note: 3DE_N = 1 is upon the initial scan and 3DE_N = 1000 is upon the 1000^th scan.
