Assessment of active areas for the oxygen evolution reaction on an amorphous iridium oxide surface

Regina M. Kluge et al.

Summary: Efficient production of hydrogen from water using electrocatalysis is hindered by slow kinetics of the oxygen evolution reaction (OER). Iridium (Ir) oxide catalysts in polymer electrolyte membrane electrolysers show promising activity and stability, but the structure-activity relations are not well understood. Noise in electrochemical scanning tunnelling microscopy (n-ECSTM) measurements on amorphous iridium oxide surfaces suggest little structure-sensitivity in OER, unlike in other catalytic reactions.

Operando visualization of the hydrogen evolution reaction with atomic-scale precision at different metal-graphene interfaces

Tomasz Kosmala et al.

Summary: The study found that thin iron films covered with monolayer graphene exhibit superior catalytic activity for the hydrogen evolution reaction compared to platinum. By evaluating noise in the tunnelling current of electrochemical scanning tunnelling microscopy, researchers discovered the exceptional activity of single iron atoms trapped within carbon vacancies and curved graphene areas on step edges. Density functional theory calculations further confirmed this sequence of activity.

In-situ detection of active sites for carbon-based bifunctional oxygen reduction and evolution catalysis

Richard W. Haid et al.

Summary: Carbon-based electrodes are increasingly popular as electrocatalysts for fuel cells and metal-air batteries due to their availability and versatility. This study investigated the surface behavior of highly oriented pyrolytic graphite under both ORR and OER conditions in 0.1 M KOH. By using noise analysis in electrochemical scanning tunneling microscopy, active sites were monitored and compared with nanoscale resolution. The results showed that step sites and defects are active for both ORR and OER, while terraces sites are largely inactive and only become involved in the OER at higher potentials. Surface degradation was evaluated during the operation, with no clear evidence of surface destruction observed in the experiments.

Monitoring the active sites for the hydrogen evolution reaction at model carbon surfaces

Regina M. Kluge et al.

Summary: Carbon is commonly used as an electrode material in electrochemical energy conversion devices and has recently attracted interest as an environmentally friendly alternative to noble metal catalysts. Research has shown that electrochemical scanning tunnelling microscopy can be utilized to pinpoint the active sites for hydrogen evolution reaction on carbon-based electrode materials. This insight can guide the synthesis of enhanced electrocatalysts by locating the active sites on doped carbon-based materials.
