Abstract Developing highly efficient and cost‐effective electrocatalysts for oxygen reduction reaction (ORR) in aqueous media is crucial for energy conversion systems such as fuel cells or Zn‐air batteries. Electrode materials from spent devices

Oxygen reduction is one of the core steps of non-emissive zero carbon energy conversion. Therefore, enhancement of its sluggish kinetics is extremely important. Very recently researchers focused on oxygen electrocatalysis at porous polymers. Here we

Biphasic oxygen reduction and hydrogen evolution are studied for almost two decades, because of favourable overpotential decrease as compared to aqueous solution. Until now, polar solvents (ε > 7) were employed as organic phase in these studies. Her

Previous electrochemical studies of redox emulsions have been mainly performed in the context of electro-organic synthesis. More recently, this research has been oriented towards applications of emulsions in flow batteries. Such biphasic systems seem

The fast and wireless estimation of moisture in sand and other bulk materials usually requires high-tech instrumentation and computation. To overcome the complexity of such systems, we have employed bipolar electrochemistry as a fast, straightforward

Lithium-ion battery (LiB) waste powder is a valuable source of various materials, including carbon and metals. Although this material exhibits electrical conductivity, nanostructured morphology, and may contain metal oxides, it has not been used as a

Catalase is known for its ability to catalyze disproportionation of hydrogen peroxide into oxygen and water. This work reports the oxygen reduction reaction (ORR) catalyzed by catalase, with a decreased activation energy manifested by a positive shif

Although the electrochemical behaviour of an aqueous dispersion of nanometer-sized redox active nanoparticles has recently received some attention, there are very few such studies of larger objects. Here, we present a study of the electrochemical beh
