“…BPE has been exploited to initiate other functionalities such as light emission, as for example electrochemiluminescence (ECL) and LED (light-emitting diode) readouts. [4][5][6][7][8] In particular, bipolar ECL (BP-ECL) is a phenomenon where luminescence is generated through redox reactions involving a luminophore and a coreactant and producing light at the surface of BEs. [9][10][11][12][13][14] Thus, ECL generates an optical readout opening various bioanalytical and microscopy opportunities.…”

“…Thus, the physico-chemical information of the coupled redox reactions is directly encoded by the current passing through the LED and its concomitant light emission intensity. [40,41] The synergy between BE and this type of microelectronic light emitting devices has been studied in order to design multiple unconventional electroanalysis platforms, [42] allowing the quantification of species ranging from organic molecules [43,44] to ions [45][46][47] and enantiomers. [48,49] Herein, we take advantage of such wireless light-emitting devices to study the synergetic effect of the composition of the anode and cathode of an electrolyzer on its electrocatalytic activity towards water splitting.…”

Water splitting has become a sustainable and clean alternative for hydrogen production. Commonly, the efficiency of such reactions is intimately related to the physico‐chemical properties of the catalysts that constitute the electrolyzer. Thus, the development of simple and fast methods to evaluate the electrocatalytic efficiency of an electrolyzer is highly required. In this work, we present an unconventional method based on the combination of bipolar electrochemistry and light‐emitting diodes, which allows the evaluation of the electrocatalytic performance of the two types of catalysts composing an electrolyzer, namely for oxygen and hydrogen evolution reactions. The integrated light emission of the diode acts as an optical readout of the electrocatalytic information, which simultaneously depends on the composition of the anode and the cathode. The electrocatalytic activity of Au, Pt and Ni electrodes, connected to the LED in multiple anode/cathode configurations, towards the water splitting reactions has been evaluated. The efficiency of the electrolyser can be represented in terms of the onset electric field (εonset) for light emission, obtaining variations that are in agreement with data reported with conventional electrochemistry. This work introduces a straightforward method for evaluating electrocatalysts and underscores the importance of material characterization in developing efficient electrolyzers for hydrogen production.

“…1–4 Commonly, light emission approaches are based on the coupling of chemical processes to microelectronic devices (such as light emitting diodes for example), fluorescent probes or electrochemiluminescence (ECL) reactions. 5–14 In particular, ECL has become a powerful tool in optical imaging, due to its high sensitivity, broad dynamic range, fast response time and low cost of analysis. 15–17 Briefly, by applying a potential step, a sequence of reactions is initiated by electrogenerated species in order to populate the excited state of a luminophore, which emits light upon relaxation.…”
