Foreign transition metals are doped into the nickel phosphide nanoparticles through a simple wet-chemical process to show high level of doping without significant distortion crystal structure and morphology, which endows excellent activity in electrochemical oxygen evolution reaction.
A simple treatment with Li-ethylenediamine alters the surface of WO<sub>3</sub> nanoparticles localized defects that form a thin disordered layer and modifies electronic structure suitable for hydrogen generation.
A new photosensitizer-free visible light-mediated gold-catalysed cis-difunctionalization reaction is developed. The was chemoselective towards silyl-substituted alkynes with excellent regioselectivity and good functional group compatibility, giving a series of quinolizinium derivatives as products. newly synthesized fluorescent compounds, named JR-Fluor-1, possessed tunable emission properties large Stokes shifts. With unique photophysical properties, the fluorophores have been applied in...
We designed and synthesized two efficient narrowband deep-blue emitters, pICz-PPO pICz-2PPO, via an acceptor modification strategy to optimize the charge carrier mobility thus addressed efficiency roll-off issue.

Chiral double-stranded helicates, formed between Cu(I) ion and C2-symmetric oligopyridines, were used for catalytic asymmetric cyclopropanation of alkenes; low catalyst loadings (0.2 mol%), high TONs (up to 404) short reaction times (30–60 min) achieved with [Cu2L2]OTf2 (L = chiral terpyridine).
Abstract The rational design of electrocatalysts with abundant active sites and high conductivity is the key to development glucose sensors. Herein, we report preparation a Cu 2+ ‐doped C 3 N 4 supported on multi‐walled carbon nanotube (MWCNT) network (Cu ‐C /MWCNT) as highly efficient non‐enzymatic sensing system. morphologic structural investigations using TEM, AFM, XRD, XPS, EPR, i‐ V response indicate successful insertion into inter‐ layers via an out‐of‐plane on‐top configuration...
Defect and phase engineering can effectively tune the activity of photocatalysts by altering their band structure active site configuration. Herein, we report phase-controlled synthesis tungsten oxide (WO3) nanoplates via a wet-chemical approach. By adjusting ratio trioctylphosphine oxide, oxygen vacancies are induced in WO3 at relatively low temperature, accompanying crystal transition from monoclinic to orthorhombic or pseudocubic phase. The experimental results DFT calculations reveal...

Bismuth is the least toxic element among heavy metals, an outstanding advantage for environmental and health considerations. Yet, utilizing bismuth as anodic electrocatalyst hindered by formation of a spreading Bi(OH)3 inhibitor layer during process. Herein, we report that nanoparticles, produced using laser ablation, can avoid such drawbacks. The production Bi(V) species assists polyol electrooxidation. For glucose, instead commonly reported gluconic acid product, enables highly selective...
