Minimizing the use of platinum (Pt) in catalysts for the oxygen reduction reaction (ORR) is critical for the commercial application of fuel cells. Here, we report a highly active carbon-supported catalyst with a low loading of Pt nanoparticles (Pt/C-

Gold is generally considered to be inert for electrochemical reactions in solid oxide fuel cells (SOFCs). It is thus used as the standard current collector to characterize the catalytic activity of various cathode materials including the state-of-the

Three different metal oxides based on Mn2O3 with TiO2 or NiO were synthesised. Pt or PtNi nanoparticles were anchored on each support, creating a set of nine samples that were tested for the oxygen reduction reaction (ORR) and the oxygen evolution re

The study of non-precious metal catalysts (NPMCs) as alternatives to platinum for oxygen reduction is crucial if the use of fuel cells is to become more widespread. Among NPMCs, pyrolyzed catalysts (Fe-N-C) are particul

Fe/N/C catalysts have been investigated as promising non-noble metal catalysts for both CO2 reduction reaction (CO2RR) and oxygen reduction reaction (ORR). However, it is unclear whether both reactions hold the same active sites. In this study, the F

Ag-Co3O4@N-doped carbon/carbon nanotubes composites are synthesized by dispersing Ag nanoparticles throughout the N-doped carbon derived from ZIF-67/CNT. In oxygen reduction reaction (ORR), the synthesized composites possess a one-step 4 electron pat

A facile method to prepare Pt–Ti intermetallic nanoparticles supported on carbon was developed. Starting from a commercial Pt/C catalyst, TiO2 layers were formed on the Pt/C then thermal annealing under a reducing condition successfully produced in
