TL;DR: In this article, three-dimensional (3D) porous Ni/Ni8P3 and Ni/N9S8 electrodes are prepared by sequential treatment of commercial Ni-foam with acid activation, followed by phosphorization or sulfurization, which can act as self-supported bifunctional electrocatalytic electrodes for direct water splitting with excellent activity toward oxygen evolution reaction and hydrogen evolution reaction in alkaline media.

TL;DR: Jiao et al. as discussed by the authors evaluated a series of heteroatom-doped graphene materials as efficient hydrogen evolution reaction (HER) electrocatalysts by combining spectroscopic characterization, electrochemical measurements, and density functional theory calculations.

TL;DR: A new electrolytic Zn-MnO2 battery has a record-high output voltage and an imposing gravimetric capacity, together with a record energy density, and should be of immediate benefit for low-cost practical energy storage and grid-scale applications.

TL;DR: In this article, the fundamental electronic, optical and chemical properties of 2D phosphorene and its suitability as a metal-free water splitting photocatalyst are assessed and compared against claims from environmental antagonists.

TL;DR: For a series of M-RuIr (M = Co, Ni, Fe), the catalytic activity dependence at fundamental level on the chemical/valence states is used to establish a novel composition-activity relationship, which permits new design principles for bifunctional electrocatalysts.
