Photocatalytic degradation of steroid hormone micropollutants by TiO2-coated polyethersulfone membranes in a continuous flow-through process Nat. Nanotechnol. (IF 39.213) Pub Date : 2022-03-31 Shabnam Lotfi, Kristina Fischer, Agnes Schulze, Andrea I. Schäfer
Micropollutants in the aquatic environment pose a high risk to both environmental and human health. The photocatalytic degradation of steroid hormones in a flow-through photocatalytic membrane reactor under UV light (365 nm) at environmentally relevant concentrations (50 ng l–1 to 1 mg l–1) was examined using a polyethersulfone–titanium dioxide (PES–TiO2) membrane. The TiO2 nanoparticles (10–30 nm)

Fast and selective reduction of nitroarenes under visible light with an earth-abundant plasmonic photocatalyst Nat. Nanotechnol. (IF 39.213) Pub Date : 2022-03-28 Aby Cheruvathoor Poulose, Giorgio Zoppellaro, Ioannis Konidakis, Efthymis Serpetzoglou, Emmanuel Stratakis, Ondřej Tomanec, Matthias Beller, Aristides Bakandritsos, Radek Zbořil
Reduction of nitroaromatics to the corresponding amines is a key process in the fine and bulk chemicals industry to produce polymers, pharmaceuticals, agrochemicals and dyes. However, their effective and selective reduction requires high temperatures and pressurized hydrogen and involves noble metal-based catalysts. Here we report on an earth-abundant, plasmonic nano-photocatalyst, with an excellent
