The development of highly active and stable oxygen evolution reaction (OER) electrocatalysts is crucial for improving the efficiency water splitting metal-air battery devices. Herein, an efficient strategy demonstrated making vacancies dominated cobalt-nickel sulfide interface porous nanowires (NiS2 /CoS2 -O NWs) boosting OER catalysis through in situ electrochemical NiS2 NWs. Because abundant structure, they can catalyze efficiently with a low overpotential 235 mV at j = 10 mA cm-2...
We report a facile nitrogenation/exfoliation process to prepare hybrid Ni-C-N nanosheets. These nanosheets are <2 nm thin, chemically stable, and metallically conductive. They serve as robust catalyst for the hydrogen evolution reaction in 0.5 M H2SO4, or 1.0 KOH PBS (pH = 7). For example, they catalyze H2SO4 at an onset potential of 34.7 mV, overpotential 60.9 mV (at j 10 mA cm-2) with remarkable long-term stability (∼10% current drop after 70 h testing period). promising non-Pt practical reaction.
Abstract Electrochemical water splitting to produce hydrogen and oxygen, as an important reaction for renewable energy storage, needs highly efficient stable catalysts. Herein, FeS 2 /CoS interface nanosheets (NSs) bifunctional electrocatalysts overall are reported. The thickness disordered structure with rich defects of NSs confirmed by atomic force microscopy high‐resolution transmission electron microscopy. Furthermore, extended X‐ray absorption fine spectroscopy clarifies that sulfur...
Highly active, cost-effective, and durable catalysts for oxygen evolution reaction (OER) are required in energy conversion storage processes. A facile synthesis of CoFe layered double hydroxide (CoFe LDH) is reported as a highly active stable catalyst. By varying the concentration metal ion precursor, Co/Fe ratios LDH products can be tuned from 0.5 to 7.4. The structure electrocatalytic activity obtained were found show strong dependence on ratios. Co2 Fe1 sample exhibited best performance...
The concept of aggregate science was proposed to explain changes in materials performance that accompany the generation aggregates, but aggregation-triggered multifunction improvements a class have rarely been reported. Herein, we present first report new multifunctional aggregation-induced emission (AIE) luminogens (AIEgens) based on 5,10-diarylphenazine (DPZ) derivates with full-wavelength emission. Intriguingly, multiple properties, such as fluorescence intensity and free radical type I...
A rational design of highly active and robust catalysts based on earth-abundant elements for hydrogen evolution reaction (HER) is essential future renewable energy applications. Herein, we report the synthesis a new class ultrathin metallic CuFeS2 nanosheets (NSs) with abundant exposed high-index {04} facets. They serve as catalyst HER lower onset potential 28.1 mV, an overpotential only 88.7 mV (at j = 10 mA cm−2) remarkable long-term stability in 0.5 M H2SO4, which make them best system...
