Na-doped OMS-2-catalzyed highly selective aerobic oxidation of ethyl lactate to ethyl pyruvate under mild conditions

Activation of O2 over three-dimensional manganese oxide nanoprisms under ambient conditions towards oxidative removal of aqueous organics

“…However, it still kept the cryptomelane crystal phase from the XRD results. 75 When Bi was used as the sole dopant, uniform nanorods were observed and the surface was smoother than that of the original OMS-2 (Fig. 3D–F).…”

Highly efficient oxidation of ethyl lactate to ethyl pyruvate with molecular oxygen over VxOy/SBA-15 catalysts

“…Similar results were also observed in earlier reports on the same reaction over Na-doped OMS-2 and meso-VTN catalysts. 21,24 When air was used as the oxidant, the catalytic performance was significantly improved, and 48.5% EL conversion and 98% EP selectivity were obtained. The highest EL conversion (95.8%) was observed under O 2 and the EP selectivity was almost unchanged.…”

“…20 In addition to H 2 O 2 and TBHP, O 2 as a green and cheap oxidant was widely used in many oxidation reactions. Meng et al 21 prepared Na-doped OMS-2 catalysts for the oxidation of EL, and 78% EL conversion and 95% EP selectivity were obtained in nitromethane at 50 °C. The doped Na enhanced the surface oxygen vacancies and reducibility of OMS-2 and thus increased the EP selectivity.…”

Adsorption of Rutin from Aqueous Solution over an OMS‐2‐Modified ZrO2 Nanocomposite

“…[21][22][23] It has been applied in catalysis, adsorption, ion-exchange, battery and semiconductivity since OMS-2 has mild acid and basic properties, porosity, mixed valence of Mn species and rich surface oxygen vacancies. [24][25][26][27][28][29][30][31] In terms of wastewater treatment, dyes and As(III) in wastewater were usually removed via adsorption over MnO 2 with alpha phase. [32] Shi's group investigated adsorption performance of transition metal-doped OMS-2 on diclofenac in aqueous phase and Ce-doped OMS-2 could be an efficient adsorbent.…”
