Renewable energy sources are considered to play a key role in the future mix, with hydrogen being an important carrier as long-term storage option. Polymer electrolyte membrane (PEM) water electrolysis (WE) allows relatively quick and convenient production of pure from only electricity; thus it is one most practical ways consume renewable for green production. The efficiency splitting largely depends on intrinsic activity, selectivity, stability oxygen evolution electrocatalysts, currently based noble metals (e.g., Ir or Ru), PEM technology. utilization various support materials has been proposed decreasing metal loading, reducing costs technology, enhancing catalytic activity durability. This minireview addresses recent advances research prospects area Ir-based supported catalysts. Besides addressing durability catalysts, consideration given their applications WE cells. It concludes mention challenges perspectives.

Complex geometries that are difficult or impossible to achieve with traditional manufacturing techniques can be created through 3D printing today. This method lead improved performance and novel designs for gas diffusion electrode (GDE) substrates. In this study, GDE samples prepared by the subjected Pt coating varying thicknesses using electron beam evaporation (E-beam) method. denoted BM-C0 (bare), BM-C1 (0.20 μm Cr + 0.20 Pt), BM-C2 0.45 Pt). After process, oxygen evolution reaction (OER) of GDEs is examined in 0.5 M H2SO4. The maximum current density value obtained as 77.86 mA/cm2 at 1.7 V from sample. A change charge transfer coefficient has been determined Tafel curves, resulting partial oxidation Pt. It best charge-transfer rate electrode/electrolyte interface belongs among samples. According LSV results, it revealed electrochemical sample 14.01 times more compared other GDEs. Furthermore, anticipated a Pt-coated thin film could significantly enhance competitive level energy conversion devices.
