Oxidation of Pharmaceuticals during Ozonation and Advanced Oxidation Processes
Environmental Science & Technology, 2003This study investigates the oxidation of pharmaceuticals during conventional ozonation and advanced oxidation processes (AOPs) applied in drinking water treatment. In a first step, second-order rate constants for the reactions of selected pharmaceuticals with ozone (k(O3)) and OH radicals (k(OH)) were determined in bench-scale experiments (in brackets ...

Degradation of formaldehyde by advanced oxidation processes
Journal of Environmental Management, 2012The degradation of formaldehyde in an aqueous solution (400 mg L(-1)) was studied using photolysis, peroxidation and advanced oxidation processes (UV/H(2)O(2), Fenton and photo-Fenton). Photolysis was the only process tested that did not reduce formaldehyde concentration; however, only advanced oxidation processes (AOPs) significantly decreased ...

Recent advances in enzymatic oxidation of alcohols
Current Opinion in Chemical Biology, 2018Enzymatic alcohol oxidation plays an important role in chemical synthesis. In the past two years, new alcohol oxidation enzymes were developed through genome-mining and protein engineering, such as new copper radical oxidases with broad substrate scope, alcohol dehydrogenases with altered cofactor preference and a flavin-dependent alcohol oxidase with ...

Amorphous Oxide Nanostructures for Advanced Electrocatalysis
Chemistry – A European Journal, 2019AbstractAmorphous oxides have attracted special attention as advanced electrocatalysts owing to their unique local structural flexibility and attractive electrocatalytic properties. With abundant randomly oriented bonds and surface‐exposed defects (e.g., oxygen vacancies) as active catalytic sites, the adsorption/desorption of reactants can be ...
