The cathodic oxygen reduction reaction (ORR) is essential in the electrochemical energy conversion of fuel cells. Here, through NH3 atmosphere annealing a graphene oxide (GO) precursor containing trace amounts Ru, we have synthesized atomically dispersed Ru on nitrogen-doped that performs as an electrocatalyst for ORR acidic medium. Ru/nitrogen-doped GO catalyst exhibits excellent four-electron activity, offering onset and half-wave potentials 0.89 0.75 V, respectively, vs reversible...

As a promising bifunctional electrocatalyst for water splitting, NiFe-layered double hydroxide (NiFe LDH) demonstrates an excellent activity toward oxygen evolution reaction (OER) in alkaline solution. However, its hydrogen (HER) is challenged owing to the poor electronic conductivity and insufficient electrochemical active sites. Therefore, three-dimensional self-supporting metal hydroxide/oxide electrode with abundant vacancies prepared by electrodepositing CeO x nanoparticles on NiFe LDH...

Recharging batteries operate at sub-zero temperature is usually limited by the slow ion diffusion and uneven charge distribution low temperature. Here, we report a strategy to regulate electric field thermal simultaneously, creating fast uniform deposition surroundings for potassium in metal (PMBs). This regulation achieved using highly ordered 1D nanoarray electrode which provides dense flat surface uniforming high conductivity reducing fluctuation. Consequently, this could achieve...

Abstract Emerging high entropy compounds (HECs) have attracted huge attention in electrochemical energy‐related applications. The features of ultrafine size and carbon incorporation show great potential to boost the ion‐storage kinetics HECs. However, they are rarely reported because high‐temperature calcination tends result larger crystallites, phase separation, reduction. Herein, using NaCl self‐assembly template method, by introducing a high‐pressure field process, atom diffusion...
