摘要: The development of a new heterogeneous Fenton-like catalyst is highly desired. Herein, we reported simple and efficient method for the preparation colloidal nanocomposites consisting carbon dots dodecylbenzenesulfonate (DBS)-layered double hydroxides (LDHs). resulting nanocatalyst can function as an effective decomposition acidified H2O2 to generate abundant hydroxyl radicals (·OH). With aid chemiluminescence (CL) technique, electron spin resonance (ESR) measurements ion chromatography (IC) separation demonstrated that unique structural configuration dot-DBS-LDH was responsible catalytic activities toward decomposition. fabricated material introduced novel family nanocatalysts with environmental friendliness, cost effectivity, superior efficiency ·OH radicals. Such c...
