Fabrication of Mn₂O₃ nanorods: an efficient catalyst for selective transformation of alcohols to aldehydes

Abstract

Self-assembled high surface area Mn2O3 nanorods have been fabricated through an effective polymer–surfactant interaction and their outstanding catalytic property for the selective transformation of alcohols to aldehydes has been discovered.

Controlled Synthesis of Highly Crystallized Mesoporous Mn2O3 and Mn3O4 by Using Anionic Surfactants

“…In addition, the peaks at 1300-1500 cm À1 and 2800-3000 cm À1 in the as-prepared Mn 3 O 4 sample correspond to the ÀCH 2 À bending and stretching vibrations, respectively,w hich is as ignature of the presence of SDS template. [37][38][39] Remarkably,t he Raman modes of both mesoporous samples show an intense peak located between 570 and 700 cm À1 .F or the meso-Mn 2 O 3 catalyst,t he broad band observed at 633 cm À1 was assigned to the MnÀOs tretching vibration of the MnO 6 group. [40] The peak position of meso-Mn 3 O 4 is shifted by 10 cm À1 towards higher values compared to meso-Mn 2 O 3 because of the mixed Mn oxidation states.…”

Polyvinylpyrrolidone-sodium dodecylsulfate complex is a family of pseudo-polyanions with different charge densities: Evidence from capillary electrophoresis, capillary viscosimetry and conductometry

“…Mixtures of neutral polymer and anionic surfactant in aqueous solution present special colloidal and interfacial properties that have great theoretical significance for molecular self-assembly, and are widely used for industrial applications [1][2][3][4] and nanoscience [5][6][7][8]. Interactions between sodium dodecylsulfate (SDS) and polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) have been extensively studied by tensiometry [9], conductometry [10,11], viscosimetry [12] and other methods [13].…”

Decomposition of 2-naphthol in water by TiO₂ modified with SnO<i>_x</i> or (Mn, Sn)O<i>_x</i> and MnO<i>_x</i>

“…7)11) Their decomposition activity (oxidation) is attributed to the Marsvan Krevelen (MvK) mechanism. 8),10),11) Very recently, we modified a TiO 2 surface with MnO x by chemisorption calcination cycle (CCC) processing.…”
