Electrochemical activation is an effective and simple method to obtain in-situ surface modification of MOF materials away from thermal decomposition. However, the impact rate related phase transformation on OER intrinsic activity during electrochemical process often overlooked. Herein, we synthesized a kind Co-MOF with unique crystal structure in which center metals were coordinated oxygen nitrogen atoms two water molecules organic linkers. The bond strength between can be modulated by...
Atomically thin metallic Ni<sub>3</sub>N nanosheets fabricated as the hydrogen evolution cathode exhibit remarkable HER activity close to that of a commercial Pt/C electrode. The Ni atoms accompanied by surrounding N on N–Ni surface demonstrate small Δ<italic>G</italic><sub>H*</sub> 0.065 eV due Ni–N co-effect, and thus act most active sites.
Abstract The development of efficient earth-abundant electrocatalysts for oxygen reduction, evolution, and hydrogen evolution reactions (ORR, OER, HER) is important future energy conversion storage devices, which both rechargeable Zn–air batteries water splitting have raised great expectations. Herein, we report a single-phase bimetallic nickel cobalt sulfide ((Ni,Co)S 2 ) as an electrocatalyst OER ORR. Owing to the synergistic combination Ni Co, (Ni,Co)S exhibits superior electrocatalytic...

Abstract Catalytic diastereo‐ and enantioselective hydroalkenylation of 3,3‐disubstituted cyclopropenes with readily accessible alkenylboronic acids, promoted by a chiral phosphine/Co complex, is presented. Such process constitutes the unprecedented direct introduction wide range alkenyl groups onto cyclopropane motif to afford multisubstituted cyclopropanes in up 95 % yield greater than 95:5 d.r. 99:1 e.r. Functionalization products delivered enantioenriched that are otherwise difficult access.
The spin state of antibonding orbital (eg) occupancy in LaCoO3 is recognized as a descriptor for its oxygen electrocatalysis. However, the Co(III) cation typical (LCO) favors low state, which mediocre absorbing oxygen-containing groups involved evolution reaction (OER) and reduction (ORR), thus hindering further development Herein, both experimental theoretical results reveal enhancement bifunctional electrocatalytic activity by N doping. More specifically, electron energy loss spectroscopy...
Poor electronic conductivity and an inert basal plane restrict the further enhancement of hydrogen evolution reaction (HER) in 2H-phase MoSe2. Herein, we synthesized MoSe2 nanosheet arrays on carbon cloth induced multivacancies their via high-energy Ar2+ beam irradiation, which are confirmed by Raman, electron spin resonance, X-ray photoelectron spectroscopy, high-resolution transmission microscopy analyses. Electrical measurement results indicate that these vacancies can effectively improve...

Mass spectrometry imaging (MSI) has become a powerful tool in diverse fields, such as chemistry, physics, materials, and life science. Although research is getting more prevalent, it limited by high-resolution (HR) instrumental development. Recently, unceasing efforts have been made toward taking spatial resolution from the microscale to nanoscale, especially for near-field based techniques. These emerging unique features behind mass (HR-MSI) provide new possibilities various aspects of...

Abstract Manipulating electronic and magnetic properties of two-dimensional transitional-metal dichalcogenides has raised a lot attention recently. Herein we report the synthesis ferromagnetic phase-transfer induced room temperature behavior in 1 T@2H-MoSe 2 nanosheets. Experimental results indicate saturated magnetization compound increases first then decreases as increasing T-MoSe phase, where 65.58% phase incorporation 2H-MoSe could enhance from 0.32 memu/g to 8.36 memu/g. Besides,...
Outstanding magnetic properties are highly desired for two-dimensional (2D) semiconductor nanosheets due to their potential applications in spintronics. Metal-free ferromagnetic 2D materials whose magnetism originated from the pure s/p electron configuration could give a long spin relaxation time, which plays vital role information transfer. Here, we synthesize g-C3N4 with room temperature ferromagnetism induced by P doping. In our case, Curie of doped reaches as high 911 K and precise...
