- Abstract
Исследована кинетика и селективность непрямого электрокаталитического окисления резорцина активными формами кислорода (АФК), генерированными in situ из кислорода в газодиффузионном электроде (ГДЭ) на основе мезоструктурированного углерода СМК‑3 и анодах из Pt и Pb/PbO2 при различных рН. Показана высокая эффективность процесса окисления резорцина (99 %) в системе c ГДЭ и Pt при рН =10 в растворе 0.05 M NaOH: 0.5 М Na2SO4 (3:1), и Pb/PbO2 + Fe2+ при рН=2 (99 %) в растворе 0.5 М Na2SO4:0.1 M H2SO4 (3:1), предложена схема его окисления
Kinetics and selectivity of indirect electrocatalytic resorcinol oxidation by active oxygen forms (AOF) in situ generated from oxygen in gas diffusion electrode (GDE) mesostructured carbon CMK‑3 and Pt, Pb/PbO2 at different pH were studied. The high resorcinol oxidation process effectivity in both Pt-GDE at pH=10 (99 %) and Pb/PbO2 + Fe2+ at рН=2 (99 %) systems was shown; the resorcinol oxidation scheme was proposed
