While the field of carbon-based metal-free electrocatalysts for oxygen reduction reaction (ORR) has experienced great progress in recent years, fundamental issue origin ORR activity is far from being clarified. To date, activities these are usually attributed to different dopants, while contribution intrinsic carbon defects been explored little. Herein, we report high defective nanocages, which better than that B-doped nanotubes and comparable N-doped nanostructures. Density functional...
High volumetric energy density combined with high power is highly desired for electrical double‐layer capacitors. Usually the performance improved by compressing carbon material to increase but at much expense of due deviation compressed porous structure from ideal one. Herein authors report an efficient approach and optimize collapsing nanocages via capillarity. Three samples decreasing sizes meso‐ macropores provide us model system demonstrate correlation structure. The results indicate...
Abstract Two‐dimensional (2D) transition‐metal carbides (MXenes) are widely adopted as potential electrocatalysts for the hydrogen evolution reaction (HER) owing to their metallic conductivity, rich tunable surface chemistry, and atomic thickness with highly exposed active sites. Previously published theoretical results indicate that MXenes functionalized entirely oxygen have lower Δ G H* HER. However, contain many terminal F groups on basal plane, which is detrimental Herein, development of...
Abstract For mass production of high‐purity hydrogen fuel by electrochemical water splitting, seawater electrolysis is an attractive alternative to the traditional freshwater due abundance and low cost in nature. However, undesirable chlorine ion oxidation reactions occurring simultaneously with greatly hinder overall performance electrolysis. To tackle this problem, electrocatalysts high activity selectivity purposely modulated coordination alkaline environment are urgently required....
The development of highly active, inexpensive, and stable bifunctional oxygen reduction reaction (ORR) evolution (OER) catalysts to replace noble metal Pt RuO
Developing economical and efficient electrocatalysts with nonprecious metals for the hydrogen evolution reaction (HER), especially in water-alkaline electrolyzers, is pivotal large-scale production. Recently, both density functional theory (DFT) calculations experimental studies have demonstrated that earth-abundant MoS2 a promising HER electrocatalyst acidic solution. However, kinetics of alkaline solution still suffer from high overpotential (90–220 mV at current 10 mA cm–2). Herein, we...
Exploring cheap and stable electrocatalysts to replace Pt for the oxygen reduction reaction (ORR) is now key issue large-scale application of fuel cells. Herein, we report an alloyed Co–Mo nitride electrocatalyst supported on nitrogen-doped carbon nanocages (NCNCs) which combines merits cobalt molybdenum nitride, showing high activity comparable that progressively enhanced stability with increase in Mo ratio. The typical Co0.5Mo0.5Ny/NCNCs catalyst demonstrates excellent ORR performance...
Single-atom catalysts (SACs) with magnetic elements as the active center have been widely exploited for efficient electrochemical conversions. Understanding catalytic role of spin, and thus modulating spin density a single-atom center, is profound fundamental interest technological impact. Here, we synthesized ferromagnetic single Co atom on TaS2 monolayers (Co1/TaS2) model system to explore spin–activity correlation oxygen evolution reaction (OER). A adsorbed at hollow site (CoHS)...
The coordination environment of single-atom catalysts (SACs) plays a crucial role in determining the energy conversion efficiency related electrochemical devices. Herein, series Co-based SACs (Co1-SACs) was tuned to correlate chemical structures these with their electrocatalytic performance. optimized Co1-SACs containing Co-S2N2 sites are electrocatalytically active both oxygen reduction reaction (ORR) and hydrogen evolution (HER), which were carried out alkaline media. exhibit high ORR...
Abstract The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend whether N is deposited in reduced (mainly as ammonium) or oxidized forms nitrate) subsequent fate each. However, fates two key reactive their contributions to C sinks are unclear. Here, we analyze results from 13 ecosystem-scale paired 15 N-labelling experiments temperate, subtropical, tropical forests. Results show that total retention similar for ammonium...
