Nickel nanoparticles encapsulated in few-layer nitrogen-doped graphene (Ni@NC) are synthesized by using a Ni-based metal-organic framework as the precursor for high-temperature annealing treatment. The resulting Ni@NC materials exhibit highly efficient and ultrastable electrocatalytic activity toward hydrogen evolution reaction oxygen well overall water splitting alkaline environment.

Better living through water-splitting Chemists have known how to use electricity split water into hydrogen and oxygen for more than 200 years. Nonetheless, because the electrochemical route is inefficient, most of made nowadays comes from natural gas. Seh et al. review recent progress in electrocatalyst development accelerate water-splitting, reverse reactions that underlie fuel cells, related oxygen, nitrogen, carbon dioxide reductions. A unified theoretical framework highlights need catalyst design strategies selectively stabilize distinct reaction intermediates relative each other. Science , this issue p. 10.1126/science.aad4998

Over the past few decades, design and development of advanced electrocatalysts for efficient energy conversion technologies have been subjects extensive study. With discovery graphene, two-dimensional (2D) nanomaterials emerged as some most promising candidates heterogeneous due to their unique physical, chemical, electronic properties. Here, we review 2D-nanomaterial-based selected electrocatalytic processes. We first discuss advances in 2D based on different compositions functions followed by specific principles. Following this overview, various processes involved water cycle, carbon nitrogen cycle from fundamental conception functional application. place a significant emphasis engineering strategies influence these intrinsic material performance, such properties adsorption energetics. Finally, feature opportunities challenges ahead electrocatalysts. By considering theoretical calculations, surface characterization, electrochemical tests, describe relationships between structure, energy, apparent activity wide variety with goal providing better understanding emerging at atomic level.

Spinels with the formula of AB2O4 (where A and B are metal ions) properties magnetism, optics, electricity, catalysis have taken significant roles in applications data storage, biotechnology, electronics, laser, sensor, conversion reaction, energy storage/conversion, which largely depend on their precise structures compositions. In this review, various spinels controlled preparations oxygen reduction/evolution reaction (ORR/OER) beyond summarized. First, composition structure introduced. Then, recent advances preparation solid-, solution-, vapor-phase methods summarized, new particularly highlighted. The physicochemical characteristics such as compositions, structures, morphologies, defects, substrates been rationally regulated through approaches. This regulation can yield improved ORR/OER catalytic activities, further accelerate speed, prolong life, narrow polarization fuel cells, metal-air batteries, water splitting devices. Finally, magnetic, optical, electrical, OER/ORR also discussed. future considered to be closely related environmental issues, will aided by development species advanced characterizations.

Electrochemical energy storage by making H2 an carrier from water splitting relies on four elementary reactions, i.e., the hydrogen evolution reaction (HER), oxidation (HOR), oxygen (OER), and reduction (ORR). Herein, central objective is to recommend systematic protocols for activity measurements of these reactions benchmark activities comparison, which critical facilitate research development catalysts with high stability. Details electrochemical cell setup, measurements, data analysis used quantify kinetics HER, HOR, OER, ORR in acidic basic solutions are provided, examples state-of-the-art specific mass date given. First, experimental setup discussed provide common guidelines including design, reference electrode selection, counter concerns, working preparation. Second, protocols, collection processing such as ohmic- background-correction catalyst surface area estimation, practice testing comparing different classes recommended. Lastly, some benchmarked comparison across laboratories.
