Electrocatalysts for oxygen evolution reaction : Innovative investigation methods for screening and mechanisms
No full textThe oxygen evolution reaction is one of the most important electrochemical phenomena, especially for both its implications in energy conversion devices (electrochemical and photoelectrochemical water splitting) and for its importance in life science.
Quite recently, new investigative methods based on the use of microelectrodes (the scanning electrochemical microscope and the cavity-microelectrode1,2) have opened new paths for understanding fundamental mechanisms in electrocatalysis in general, and for oxygen evolution reaction in particular. At the same time, new methods for the rapid screening and for the visualization of the experimental data have been developed and applied to different materials.
The rapid screening methods are based on the use of SECM, in the sg-tc mode, by adopting the innovative “shielded tip” approach3, or by applying a pulsed potential profile at the substrate. With these methods, mixtures of SnO2-IrO2 were studied.
The selection of the right material for practical applications also implies a knowledge of the candidates’ behaviour under different conditions (applied potential, pH). In this case, the collection of experimental could be in vain without an effective method of displaying them. For this reason, a new kind of 3D diagram, the dynamic potential/pH plot4 (DPPDs) is proposed for different materials.

Recent developments on the rapid screening of electrocatalysts by scanning electrochemical microscopy
No full textScanning Electrochemical Microscopy is a scanning probe technique which is
becoming a leading electrochemical technique. The possibility of using a movable
microelectrode which can be scanned over a surface is one of the most attractive
features. In turn, the substrate can assume different natures, from biological systems to
electrocatalytic surface, from photoactive materials to nanostructured textures, thus
making the technique extremely flexible.
In the most recent years, SECM is being applied to study libraries of materials useful as
electrocatalysts or photoelectrocatalysts in energy conversion devices
1-3
.
In this work, recent results on the rapid screening of electrochemical activity of
material libraries toward the oxygen evolution/reduction reactions are shown and
discussed.
The effectiveness of these methods is proved by digital simulations.
Both methods were applied on model mixtures based on the Ir-O system, considered as
promising materials for the preparation of operative devices.
Experimental results obtained by SECM are confirmed by voltamperometric and
physico-chemical techniques.
