TL;DR: In this article, a hierarchically porous Ni 3 S 2 nanorod array foam was successfully prepared through a simple hydrothermal process assisted by the pretreatment with HCl. The resulting hierarchical porous nanostructures exhibits excellent catalytic activity and stability towards both HER and OER with low overpotential of 200mV and 217mV at current density of 10mA cm −2 for HER and oER, respectively, which are among the best nonnoble metal HER/OER electrocatalysts reported in literatures.

TL;DR: Novel N, S co-doped graphene electrodes, as efficient metal-free electrocatalysts, show a direct four-electron reaction pathway, high onset potential, high current density and high stability for the oxygen reduction reaction.

TL;DR: In this article, a facial one-pot hydrothermal method was used to load Fe2O3 supported on nitrogen-doped graphene hydrogel and obtain a specific capacitance as high as 618 F g/1 at discharge current density of 0.5 A g/g/1.

TL;DR: In this article, a one-step hydrothermal method was developed to synthesize a hybrid material consisting of NiCo2S4 nanocrystals grown on reduced graphene oxide as an efficient nonprecious electrocatalyst for the oxygen reduction reaction (ORR) in alkaline medium.

TL;DR: The BCN graphene shows significantly enhanced specific capacitance due to boron and nitrogen co-doping, which permits higher overall doping levels.
