A chemistry platform for the fast continuous synthesis of III–V quantum dots is demonstrated. III-nitride QDs are prepared by using short residence times (less than 30 s) in a one-step process with supercritical solvents. GaN via this route exhibit strong UV photoluminescence structuring emission signal at low temperature (5 K), confirming their high quality. An example metal site substitution ...

A novel freeze-drying accompanied by direct pyrolysis method was conducted to fabricate porous N, P co-doped carbon-coated ultrafine Co2P nanoparticles (Co2[email protected]) using deoxyribonucleic acid (DNA). DNA, for the first time, is used as a precursor of carbon substrate, well an in-situ source preparation Co2P. Benefiting from and carbon, Co2[email protected] shows excellent performance ...

This research studies the effect of pre-oxidation on physical and electrochemical properties electrospun polyvinylpyrrolidone (PVP)-derived carbon composites cobalt phosphides by comparing carbonized non-pre-oxidized (NPO) pre-oxidized (PO) samples used as anode materials for lithium-ion batteries. The X-Ray diffraction (XRD) patterns revealed formation CoP Co2P in both while presence amorphous...

It remains a challenge to develop efficient electrocatalysts in neutral media for hydrogen evolution reaction (HER) due the sluggish kinetics and switch of rate determining step. Although metal phosphides are widely used HER catalysts, their structural stability is an issue oxidization, performance requires improvement. Herein, new material, i.e., grapevine-shaped N-doped iron phosphide on carb...

Abstract Although transition metal phosphide electrocatalysts display unique electronic structure that serves as functional centers for hydrogen evolution reaction, the synthesis of this class materials oxygen remains a challenge due to complex multielectron transfer pathways and sluggish reaction kinetics. This study details an in‐situ modification transformation cyanide‐bridged nickel‐iron (C...

To explore the chemical analogy between thorium and heavier actinides in soft anionic environments, three new thorium phosphides (ThCuP2, β-ThCu2P2, and ThCu5P3) have been prepared through solid-state reactions using CuI as a reaction promoter. The structure of ThCuP2 can be described as a filled UTe2-type with both dimeric P24- and monomeric P3- anions, in which Th is coordinated by eight P at...
