Exploring matrix effects on photochemistry of organic aerosols [PDF]
, 2014 This work explores the effect of the environment on the rate of photolysis of 2,4-dinitrophenol (24-DNP), an important environmental toxin. In stark contrast to the slow photolysis of 24-DNP in an aqueous solution, the photolysis rate is increased by ...

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor
Angewandte Chemie, EarlyView.Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...
