Oxidation reactions are highly important chemical transformations that still require harsh reaction conditions and stoichiometric amounts of chemical oxidants that are often toxic. To circumvent these issues, olefins oxidation is achieved in mild conditions upon irradiation of an aqueous solution of the complex [Ru(bpy)3 ](2+) and the enzyme laccase. Epoxide formation is coupled to the light-dr...

A rare hybrid Metal-Oxide incorporated Zeolitic Imidazolate Framework, MOZIF-1, containing tetrahedral Zn(II) and Mo(VI) centres has been synthesized. MOZIF-1 can degrade methyl orange and orange II dyes under visible light. Na3[PMo12O40] is the source of Mo(VI) in MOZIF-1.

A facile two-step strategy was developed to fabricate yellow fluorescent glutathione-Au nanoclusters/zeolitic imidazolate framework-8 nanoparticles (GSH-Au NCs/ZIF-8 NPs) and their derived Au/ZnO NPs, which exhibited visible light photocatalytic hydrogen evolution together with degradation of Rhodamine B (RhB).

Permeable reactive barrier (PRB) containing zero valent iron (ZVI), plaster and additives to make a porous composite structure, was tested remove an organic nitro compound as model pollutant. An aqueous solution of 4-nitroaniline (PNA) passed through column chemical degradation quantified by UV-Vis spectroscopy. PNA reduced p-phenylenediamine the rate reduction strongly related ZVI amount, poll...

Titania nanoparticles sensitized with metal-free organic dye exhibit high visible-light activities for the redox conversion of water pollutants in a wider pH range in comparison with TiO(2) sensitized with ruthenium bipyridyl complexes.

• GHG footprints of plastic waste chemical recycling to olefins are quantified. benefits quantified relative incumbent incineration with energy recovery. Chemical provides in the order 0.82 kg CO 2 -eq./kg waste. Future developments further increases from 2030. Dealing heterogeneous – i.e., high polymer heterogeneity, additives, and contaminants lowering greenhouse gas (GHG) emissions productio...
