  • A transition-metal-free synthetic strategy for C–H alkylation of electron-poor aromatics is reported, which selectively alkylates the most electrophilic position of electron-deficient aromatics to exhibit ‘anti-Friedel–Crafts’ selectivity. The mechanism is driven via electron donor–acceptor complex photoinitiation with a propagative radical anion mechanism, enabling mild conditions for late-stage drug functionalization.

  • Efficient catalysts for the oxygen-evolution reaction, especially in alkaline media, are highly desired because of their application in various energy technologies. Now, a gold-supported NiCeOx catalyst is shown to have excellent catalytic activity due to synergistic geometric and electronic effects.

  • The surface oxygen storage capacity is an important metric of catalytic activity, but its dependence on strain is not well characterized. Here, the authors show the surface oxygen nonstoichiometry in coherently strained CeO2-δ films increases non-monotonically with biaxial strain.

  • Nickel–iron and cobalt–iron (oxy)hydroxides are state-of-the-art electrocatalysts for oxygen production in alkaline conditions. Now, the addition of high-valent dopants has been demonstrated to further propel the catalytic rate in these materials by an order of magnitude.

  • CO2 electrolysers store electricity as CO or other chemical fuels, but can suffer from carbon deposition at the electrodes. Skafte et al. identify a mechanistic route to inhibiting carbon build-up in ceria-based electrolysers and build a cell that operates beyond the thermodynamic carbon deposition threshold.
