• Chemistry Research Institute (ICRI) in Warsaw. In the first stage, the efficiency of electrochemical oxygen reduction was measured using the rotating disc-ring electrode (RRDE) technique. The measurements were conducted in a four-electrode electrochemical cell using a RRDE (Pine Instruments, United States

• method. CTF-1-600 and Ni/CTF-1-600 show high catalytic activity towards OER and a clear activity for the electrochemical oxygen reduction reaction (ORR). Ni/CTF-1-600 requires 374 mV overpotential in OER to reach 10 mA/cm2, which outperforms the benchmark RuO2 catalyst, which requires 403 mV under the

• gaining tremendous attention due to its importance in many fields, including water treatment technologies. Oxidized graphitic carbon-based materials have been recently proposed as an alternative to metal-based catalysts in the electrochemical oxygen reduction reaction (ORR), and in this work we unravel

• method opens a new scheme for the single-step large-scale production of functionalized carbon-based catalysts (yield ≈45% by weight) that have varying functionalities and can deliver peroxide via the electrochemical ORR process. Keywords: electrochemical oxygen reduction; functionalized carbon
