Lithium/air batteries have the potential to substantially outperform best battery system nowadays on market. Oxygen reduction reaction (ORR) at cathode in an aprotic organic lithium electrolyte is well-known limit discharge rate and capacity of lithium/air batteries. In this study, characteristics Li/air cells with cathodes made different carbon materials were examined. The results showed that ORR kinetics can be drastically improved by using effective catalyst, achieving higher voltage...
Pyrite FeS<sub>2</sub>effectively adsorbs polysulphide anions by forming active Li<sub>2</sub>S<sub>n</sub>–FeS<sub>2</sub>complexes, which significantly stabilise the capacity retention of Li–S batteries.
A class of Pd–Ni–P electrocatalysts are prepared for the ethanol electrooxidation reaction (EOR). X-ray diffraction and transmission electron microscope reveal that synthesized catalyst possesses a more amorphous structure with smaller particle sizes when compared Pd–Ni sample without P control Pd black (Pd-blk) sample. The contains double number electrocatalytically active sites (12.03%) (6.04%) Pd-blk (5.12%) samples. For EOR, has lowest onset potential (−0.88 V vs SCE), most negative peak...
The ability to control the surface composition and morphology of alloy catalysts is critical for achieving high activity durability oxygen reduction reaction (ORR) fuel cells. This report describes an efficient surfactant-free synthesis route producing a twisty nanowire (TNW) shaped platinum–iron (PtFe) catalyst (denoted as PtFe TNWs) with controllable bimetallic compositions. TNWs optimal initial ∼24% Pt are shown exhibit highest mass (3.4 A/mgPt, ∼20 times higher than that commercial...

The reaction between nitric oxide (NO) and the Cu(II) complex Cu(dmp)2(H2O)2+ (1, dmp = 2,9-dimethyl-1,10-phenanthroline) has been quantitatively examined in solution. In neutral or alkaline aqueous solutions methanol, 1 (E1/2 0.58 V vs NHE water) is reduced by NO to give corresponding cuprous species Cu(dmp)2+ plus RONO (R H, CH3). analogous for Cu(phen)2(H2O)2+ (2, phen 1,10-phenanthroline) 0.18 V) much slower does not go completion. solutions, conjugate base of reacts with at a rate.

Glucose conversion over hierarchical lamellar MFI–Sn/Al: accommodating a three-step reaction cascade single catalyst for high yield of 5-(ethoxymethyl) furfural.
Development of Li/FeS2 rechargeable batteries has been hampered by their short cycle life. In this paper, we start with the fundamental chemistry FeS2 in a non-aqueous liquid electrolyte to analyze capacity fading mechanism and propose three facile strategies for stabilizing capacity. It is repeatedly observed that cells follows general mode consisting fast stage as Region 1, slow 2, an accelerated 3. We found 1 mainly attributed dissolution lithium polysulfide leading loss sulfur active...
Sluggish water dissociation kinetics on nonprecious metal oxide electrocatalysts is considered as the rate-limiting step for development of hydrogen evolution in alkaline media. A unique heterostructure, a distorted inverse spinel Ni–Co–O layer MoS2 plate, was developed this paper. The formation Mo–O–Co covalent bonds at interface allows inherent electron transfer from to adjacent surface and forces nucleation creation disordered spinel. Such crystal-distorted structure enables substantially...
Non-oxidative alkane dehydrogenation produces alkene and hydrogen products. The current processes face three challenges: limited conversion due to thermodynamics, rapid catalyst deactivation, CO2 emissions from process heating. A membrane reactor (MR) has the potential overcome thermodynamic limit by removing H2 in situ, but both tend deactivate quickly. Here, we report a carbon that integrates H2-permeable molecular sieve (CMS) hollow fiber membranes siliceous zeolite-supported metal...
Hydroxyapatite (HAP, Ca10(PO4)6(OH)2) has a hexagonal prismatic structure that exposes two crystalline surfaces: prism-faceted a- and basal-faceted c-surfaces. In this work, the predominant exposure of c-surface was controlled, its influences in methane oxidation reactions (combustion oxidative coupling over HAP lead-substituted (Pb-HAP), respectively) were studied. The realized by crystal orientation HAP-based catalyst film, which created an electrochemical deposition seeds on titanium...
