Efficient and stable copper tungstate catalyst for water treatment with peroxymonosulfate: Effect of synthetic pH, primary oxidant, and practical feasibility.

In this study, copper tungstate (CuWO) nanoparticles, which are highly efficient and stable catalysts for water treatment, were synthesized via a hydrothermal method under various pH conditions. CuWO synthesized at pH 10 (CuWO@10) exhibited the highest degradation efficiency and the lowest metal ion leaching. In the presence of CuWO@10 (0.

Visible light-induced photocatalytic degradation of tetrabromobisphenol A on platinized tungsten oxide.

In this study, we investigated the degradation of the flame retardant tetrabromobisphenol A (TBBPA) using platinized tungsten oxide (Pt/WO), synthesized via a simple photodeposition method, under visible light. The results of degradation experiments show a significant enhancement in TBBPA degradation upon surface platinization of WO, with the degradation rate increasing by 13.4 times compared to bare WO.

Production of Molecular Iodine via a Redox Reaction between Iodate and Organic Compounds in Ice.

The abiotic mechanism of molecular iodine (I) production from iodate (IO) remains largely unknown. Here, we demonstrate the production of I in the presence of IO and organic compounds in ice. When the solution containing IO (100 μM) and furfuryl alcohol (100 μM) at pH 3.
