A ruthenium-carbamato-complex derived from a siloxylated amine and carbon dioxide for the oxidative a-cyanation of aromatic and cyclic tertiary amines
Download2013-10-09
The ruthenium carbamate complex derived from 3-trimethoxysilyl-1- propyl amine and carbon dioxide was found to be a novel catalyst for the oxidative cyanation of aromatic and cyclic tertiary amines to corresponding a-amino nitriles in high to excellent yields by using hydrogen peroxide and...

Air- and water-stable halide perovskite nanocrystals protected with nearly-monolayer carbon nitride for CO2 photoreduction and water splitting
Download2022-04-04
Halide perovskites are exciting candidates for broad-spectrum photocatalysts but have the problem of ambient stability. Protective shells of oxides and polymers around halide perovskite nano- and micro-crystals provide a measure of chemical and photochemical resilience but the photocatalytic...

Hot hole transfer from Ag nanoparticles to multiferroic YMn2O5 nanowires enables superior photocatalytic activity
Download2022-02-22
Plasmonic hot carriers with a nonthermal distribution of kinetic energies have opened up new avenues in photovoltaics, photodetection and photocatalysis. While several articles have reported ultrafast hot electron injection from coinage metals into n-type semiconductors across Schottky barriers...

Metal-Free Sulfonate/Sulfate-Functionalized Carbon Nitride for Direct Conversion of Glucose to Levulinic Acid
Download2022-05-09
Metal-free heteroatom-doped carbonaceous materials such as carbon nitride (CN) with secondary/tertiary nitrogen-rich catalytic centers as well as chemical and thermal resilience can potentially serve as catalysts for many organic reactions. However, because of the stable alternate Csp2–Nsp2...
