Article Synopsis
  • The electrocatalytic oxygen evolution reaction (OER) is crucial for converting renewable energy into chemicals and fuels, but it is hindered by a slow reaction rate that requires a high applied potential.
  • The complexity of the OER is due to multiple electron transfers and bond-making/breaking processes, making it a challenging subject for study, traditionally relying on experimental methods and simple models.
  • Recent advancements, particularly in simulation techniques, have enhanced our understanding of OER mechanisms by gradually incorporating more complex factors and allowing for better comparisons with experimental data, while also identifying ongoing challenges in modeling these reactions.

Methane is a valuable resource and its valorization is an important challenge in heterogeneous catalysis. Here it is shown that CeO/CuO composite prepared by ball milling activates methane at a temperature as low as 250 °C. In contrast to conventionally prepared catalysts, the formation of partial oxidation products such as methanol and formaldehyde is also observed.

Water oxidation activity of pristine NiOOH is greatly enhanced by doping it with Fe. However, the precise role of Fe is still being debated. Using a first-principles DFT+U approach, we investigate the direct and indirect roles of Fe in enhancing the oxygen evolution reaction (OER) activity of NiOOH monolayers.
