The graphene-like carbon network helps in improving the affinity for polysulfides and reduces shuttle effect. Nitrogen phosphorus act as bifunctional active sites further reduce activation energy, leading to superior rate capability.

Abstract Research on transition‐metal phosphides for sodium‐ion battery anodes has received increasing attention owing to their high theoretically specific capacity. Unfortunately, the volume expansion limits further applications. Herein, a nanoflakes array Ni 2 P/three‐dimensional graphene in‐situ grown foam (Ni P/3DG) is designed as free‐standing anode material. The structure characterization indicated that P were combined with 3DG uniformly. ultrasmall particle size and uniform...

Abstract Na 3 V 2 (PO 4 ) F (NVPF) has captured significant heed for cathode materials of sodium‐ion battery (SIB), owing to its stable three‐dimensional (3D) structure channel that can accommodate + diffusion. However, NVPF is still facing with a major challenge in terms the electrochemical performance, uncontrollable morphology. Hence, it was fabricated by using two‐step hydrothermal method, whereby cuboid particles homogenous morphology and highly structural symmetry could anchor on...

Abstract Molybdenum disulfide (MoS 2 ) is a two‐dimensional layer structure with high edge energy state, resulting in chemical activity. It can be widely used the supercapacitors. Herein, novel conductive architectures of MoS /reduced graphene oxide (rGO) nanosheets was immobilized on carbon cloth (CC) via hydrothermal method.

This paper described an effective synthetic route for the production of higher alcohols via syngas using CuZnAl catalysts prepared by complete liquid-phase method under different heat treatment pressure. The catalyst treated 1.0 MPa exhibited excellent catalytic performance with CO conversion 38.1% and mass fraction in total 65.9%. Compared that was atmospheric pressure, high pressure formed a complex spinel structure, amount Cu+ species decreased, but pore volume size became larger. A...

K3PO4/NaX catalysts were prepared by loading potassium phosphate on NaX zeolite, and the catalytic performance was studied for side-chain alkylation of toluene with methanol to styrene ethylbenzene. Combined characterization XRD, TPD-NH3, TPD-CO2, FTIR determination phosphorus content, it is revealed that firstly, P element loaded catalyst surface can prominently promote percentage middle base sites, which will accordingly enhance selectivity products (styrene ethylbenzene) toluene;...

Transition-metal high-entropy oxides (HEOs) show superior electrochemical properties and excellent long-term cycling stability in secondary batteries due to their entropy stabilization effect. However, the effects on storage mechanisms of Na+ remains an open question, especially considering its larger ionic radius, sluggish kinetics movement, serious volumetric expansion.
