  MnO Octahedral Nanocrystals and MnO@C Core−Shell Composites:  Synthesis, Characterization, and Electrocatalytic Properties

  摘要：

  We present a simple and facile synthesis of MnO octahedral nanocrystals and MnO@C core-shell composite nanoparticles. The synthesis is accomplished by a single-step direct pyrolysis of cetyltrimethylammonium permanganate in specially made Let-lock union cells. The products are characterized by HRSEM, HRTEM, Raman spectroscopy, and cyclic voltammetry (CV). The product consists mainly of octahedral MnO nanocrystals and MnO coated with carbon (MnO@C). The core-shell particles are observed only when the core size is smaller than 150 nm. The shape of the nanocrystals can be controlled by varying parameters such as reaction temperature and duration. As the temperature increases from 600 to 800 degrees C, the octahedral MnO crystals observed are without any carbon shell. The effect of time and temperature on the octahedral MnO nanocrystal formation is described. The electrocatalytic activities of the products are studied for oxygen reduction reaction in aqueous basic medium and are compared with bulk MnO. The MnO nanocrystals and core-shell composites exhibit higher activity than that of bulk MnO.

  report the oxidation of an established anticonvulsant and antiepileptic drug, carbamazepine, by a lipopathic oxidant, cetyltrimethylammonium permanganate (CTAP), in a nonpolar medium. 1H‐Dibenzo[b,f]azepine‐4,5‐dione is found to be the major product of the oxidation reaction. The kinetics of the reaction is studied in organic media spectrophotometrically by monitoring the disappearance of Mn(VII) at 530

  在这项贡献中，我们报告了在非极性介质中，脂类氧化剂十六烷基三甲基高锰酸铵（CTAP）对已确立的抗惊厥药和抗癫痫药卡马西平的氧化作用。1 H-二苯并[ b，f] azepine-4,5-dione被发现是氧化反应的主要产物。通过监测Mn（VII）在530 nm的消失，在有机介质中分光光度法研究了反应的动力学。发现该反应相对于卡马西平为分数级，相对于CTAP为一级。根据实验结果，提出了一种合适的离子机理，其中卡马西平以缓慢的速率确定步骤与CTAP反应，以通过非极性环状过渡态形成次锰酸酯中间体。随后，中间体分解并快速水解为二羰基产物。所提出的反应机理还受到溶剂和温度对反应速率的影响的支持。离子表面活性剂的添加可提高反应速率，

  Self-assembled water soluble MnO2 nano-composites have been synthesized by a facile one-step chemical reduction method at room temperature for the first time. MnO4−, tri-ethyl amine (TEA) and cetyltrimethylammonium bromide (CTAB) were acted as a reducing-, oxidizing-, and shape directing-agents, respectively. Stoichiometry, kinetics, and morphology of resulting colloidal particles were determined by

• Cork Suberin Molecular Structure: Stereochemistry of the C₁₈Epoxy and<i>vic</i>-Diol ω-Hydroxyacids and α,ω-Diacids Analyzed by NMR

  Suberin is the biopolyester that protects the secondary tissues of plants against environmental variability and aggressions. Cork suberin is composed mostly of C-18 omega-hydroxyacids and alpha,omega-diacids, 9,10-substituted with an unsaturation, an epoxide ring, or a vic-diol group. Although determinant for suberin macromolecular structure, the stereochemistry of these monomers is poorly studied, sometimes with contradictory results. An NMR technique was used here to assign the configuration of the 9,10-epoxy and 9,10-diol groups in C-18 suberin acids, comparing the chemical shifts of diagnostic H-1 and C-13 signals with the ones of model compounds, before and after conversion of the vic-diol group into benzylidene acetal derivatives. The relative configuration was proved to be cis in the C-18 9,10-epoxy and threo in the C-18 9,10-diol suberin acids. These monomers were present in suberin probably as racemic mixtures, as shown by polarimetry. The revealed stereochemistry allows the suberin macromolecule to be built as an ordered array of midchain kinked C-18 acids, reinforced by intramolecular hydrogen bonding.
