MnO2/γ-Al2O3 catalysts for H2O2-mediated phenol oxidation in a fixed-bed continuous-flow reactor
Description
This dataset contains the experimental data supporting the article "Use of Al2O3-supported manganese oxide-based catalysts in fixed-bed reactors for phenol decomposition and intermediate tracking" (Surfaces and Interfaces). A series of MnO2/γ-Al2O3 catalysts with nominal MnO2 loadings of 0.1, 0.5, 1.0, 2.0, 5.0 and 10.0 wt.% was prepared by wet impregnation and evaluated for H2O2-mediated phenol oxidation in a fixed-bed continuous-flow reactor, using an initial phenol concentration of 50 mg/L and a residence time of 35 min. The dataset includes the manganese content determined by flame atomic absorption spectrometry, together with BET surface areas and average pore diameters; X-ray diffraction patterns of the γ-Al2O3 support and of three of the catalysts, provided both as measured and after background subtraction and accompanied by the unmodified diffractometer files; XPS binding energies and surface Mn/Al atomic ratios; integrated hydrogen consumption from H2-TPR; integrated ammonia desorption and isoelectric points, together with the complete NH3-TPD profile of one catalyst; and the complete set of catalytic results, namely phenol conversion as a function of H2O2 concentration (30-480 mM), reaction temperature (5-45 C) and initial pH (3-9), CO2 production, and the concentrations of hydroquinone, catechol, resorcinol, malic acid and maleic acid. Each catalytic value is the mean of three independent runs with its standard deviation. Data are provided as UTF-8 CSV files organised by characterisation technique. A README file describes the folder structure, the experimental conditions, the instruments used and the scope of the dataset.
