  • The efficient catalysis of the electrochemical reduction of carbon dioxide is an important industrial process, usually performed by noble metal catalysts. Here the authors report a metal-free carbon nanofibre-based catalyst operating with a negligible overpotential, high current density and long-term stability.

  • Electrochemical reduction is one process to produce higher value chemicals from carbon dioxide, and it is typically catalysed by noble metals. Here, the authors demonstrate that molybdenum disulphide is also capable of efficiently catalysing the reaction in the presence of an ionic liquid.

  • Determining active species in non-precious metal catalysts for the oxygen reduction reaction remains a challenge due to catalyst heterogeneity. Here the authors perform gas-phase treatments on an iron-based catalyst to allow the identification of carbon-encapsulated iron nanoparticles as the active species.

  • X-ray photoelectron spectroscopy (XPS) can be used to investigate chemical bonding and elemental composition. This Primer discusses how XPS can be used to characterize thin films, including key considerations for sample preparation, experimental set-up and data analysis.
