Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

ChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Electroweak Interaction Model with an Undegenerate Double Symmetry

Symmetry, Integrability and Geometry: Methods and Applications, 2006
The initial P-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.

Exploring the Influence of Carbonaceous Material on the Photocatalytic Performance of the Composites Containing Bi–BiOBr and P25 TiO2 for NOx Remediation

ChemPhysChem, EarlyView.
Bi/BiOBr/P25 TiO2 composites are synthesized via a solvothermal method incorporating 1 wt% of a carbon‐based material (graphene oxide [GO], graphene, carbon nanotubes, or buckminsterfullerene). The GO–based composite exhibits the highest photocatalytic NOx removal efficiency (≈22% NO and ≈15% NO2) with these synergetic improvements attributed to ...

Phosphine‐Ligated Cobalt(II) Acetylacetonate Complexes

European Journal of Inorganic Chemistry, EarlyView.
Phosphines can react with cobalt acetylacetonate or Co(acac)2 to give products with drastically different structures. Depending on the ligand properties, phosphine‐ligated cobalt(II) acetylacetonate complexes can be mononuclear, dinuclear, or polymeric, 5‐coordinate or 6‐coordinate, and with or without hydrogen–bonding interactions. Monophosphines bind

Following the In Situ Pathway of Photoactivated Cyclopentadienone–NHC Iron Complexes as Ammonia–Borane Dehydrocoupling Bifunctional Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Iron complexes bearing cyclopentadienone/hydroxycyclopentadienyl and NHC ligands in combination with carbonyls are active in ammonia–borane dehydrogenation. In situ IR and scale up experiments give insight in the catalytic mechanism. Carbonyl iron complexes, bearing cyclopentadienone/hydroxycyclopentadienyl ligands and N‐heterocyclic carbene as ...

Planar‐Chiral 1,1’‐Diiminoferrocenes [Fe{η5‐C5H3‐1‐(N=CHPh)‐2‐(C≡CAr)}{η5‐C5H4(N=CHPh)}] Containing a Bulky Ethynyl Substituent Adjacent to One of the Imino Groups

European Journal of Inorganic Chemistry, Accepted Article.
The planar‐chiral stannylated diaminoferrocene [Fe{η5‐C5H3‐1‐(SnnBu3)‐2‐(NH2)}{η5‐C5H4(NH2)}] (A) and its diimine derivative [Fe{η5‐C5H3‐1‐(SnnBu3)‐2‐(N=CHPh)}{η5‐C5H4(N=CHPh)}] (B) gave unsatisfactory results in attempts to achieve Stille cross‐coupling reactions with PhBr in the presence of [PdCl2(PPh3)2] or [Pd(PPh3)4]/CuO as catalysts.
