Abstract Currently, platinum-based electrocatalysts show the best performance for hydrogen evolution. All evolution reaction catalysts should however obey Sabatier’s principle, that is, adsorption energy of to catalyst surface be neither too high nor low balance between and desorption. To overcome limitation this here we choose a composite (rhodium/silicon nanowire) catalyst, in which occurs on rhodium with large while silicon small energy. We is stable better activity than nanoparticles...
Electrolysis of water to generate hydrogen is an important issue for the industrial production green and sustainable energy. The best electrocatalyst currently available evolution reaction (HER) platinum. We herein show that iridium can be manipulated achieve a record high HER activity surpassing platinum in every aspect: lower overpotential at any given current density, higher mass all bias potentials applied catalyst cost reduction 50% same generation rate. superior was achieved by binary...
In this review, the development history, evaluation indexes, structure-types, applications and trends of quantum dot-based photodetectors are summarized.
Electrocatalytic water splitting is a desirable and sustainable strategy for hydrogen production yet still faces challenges due to the sluggish kinetics rapid deactivation of catalysts in oxygen evolution process. Herein, we utilized metal-catalyzed growth technology phosphating process fabricate self-supported electrodes (CoxPy@CNT-CC) composed carbon nanotube (CNT) arrays grown on cloth (CC); thereinto, cobalt-based phosphide nanoparticles (CoxPy) are uniformly encapsulated cavity CNTs....
Abstract Iridium (Ir) is recognized to have extremely high catalytic activity in the hydrogen evolution reaction (HER). However, there are still technical challenges maximizing utilization of Ir atoms process through dimensional regulation strategies. Herein, an innovative strategy utilized fabricate porous phosphorus‐doped iridium (P‐Ir) with a 2D structure, specifically reduction 1T phase‐IrO 2 (1T‐IrO ) nanosheets using phosphine gas. The optimized P‐Ir achieves overpotential 17.2 mV (vs...
The design of bifunctional catalytic electrodes with high performance and low cost is the key to improving hydrogen production efficiency by water splitting. However, achieving coexistence activity stability materials still faces challenges. Herein, we designed prepared a self‐supported electrode material (Ni₂P/NiSe@CNTs/CC) through combined action metal‐catalyzed carbon nanotube (CNTs) growth, selenization, phosphating. In this process, CNTs are grown in situ on cloth (CC) surface, inner...
In this paper, pure metastable phase iron vanadate (FeVO4-II) ultrathin nanosheets (50 nm in thickness) with exposed {010} facets were obtained by a mild hydrothermal process, without the use of any template or organic surfactant. The photocatalytic rate FeVO4-II was measured taking advantage their unique morphology. Furthermore, catalyst could be easily separated and reused, simply applying an external magnetic field. addition, n-type semiconductor structure, FeVO4 exhibited gas-sensing for...
Balancing the activity and stability of electrocatalytic composites in acidic hydrogen evolution reaction (HER) is still a great challenge. Although 3R-phase iridium oxide (3R-IrO2) recognized as potential competitor for oxygen (OER), its other catalytic activities have not been explored. Herein, 3R-IrO2 modified by Pt nanoparticles (Pt@3R-IrO2) exhibits certain toward HER. The Pt@3R-IrO2 with 15 wt % loading (15 Pt@3R-IrO2) displays high HER low overpotential (η@–10 mA cm–2) 19.0 mV, mass...
MoO2 nanospheres are successfully synthesized by a simple ethylene glycol-assisted hydrothermal route. The formation process is associated with the dissolution-recrystallization mechanism under glycol reduction, resulting in unique structure of that solid assembled many ultrafine primary nanoparticles. Benefiting from hierarchical structural features, electrode displays higher specific capacitance (204.7 and 197.4 Fg−1 at 1 6 A g−1, respectively) exhibits significant superior cycling...
