Direct Oxidative Cyanation of Alcohol to Nitrile over CoOx/MnO2 with Aqueous Ammonia

“…The O 1s XPS spectra can be deconvoluted into three types of oxygen components. The peak at 529.4 eV is attributed to lattice oxygen (O latt ), whereas the other two peaks at 531.7 and 533.2 eV are assigned to adsorbed oxygen (O ads ) and hydrated oxygen species (O hyd ). − The O 1s XPS spectra show that the amount of adsorbed oxygen in the 1% CoO x /MnO 2 is higher than that of MnO 2 , corresponding to the O ads /O total value increasing from 0.38 in MnO 2 to 0.42 in 1% CoO x /MnO 2 (Table S2). This shows that the content of O ads increases after doping with Co. More adsorbed oxygen in the doped catalyst is expected to have better catalytic performance toward the benzyl alcohol oxidative cyanation reaction .…”

Urchin-like hollow SiO2@γ-MnO2 microparticles for the rapid degradation of organic dyes

“…To solve this problem, many research efforts have been devoted to constructing various types of MnO 2 microparticles with high specic surface area. [24][25][26][27][28][29][30] In fact, MnO 2 microparticles have variable crystal forms and structures due to different [MnO 6 ] octahedral unit links, and the common crystal forms include a-MnO 2 , g-MnO 2 , b-MnO 2 and d-MnO 2 . 31 Among them, the octahedral units in g-MnO 2 form multi-chains along the c-axis, eventually resulting in twodimensional innite lamellae with large specic surface area, abundant adsorption sites, and high chemical activity.…”
