樓主翻譯的是這篇文獻(xiàn)吧:Optimization of the MnCeOx system for the catalytic wet oxidation of phenol with oxygen (CWAO) 其中MxCy-R4就是一個(gè)樣品的編號。 x/y是Mn/Ce的比例。 R4,R6等是不同的干燥和煅燒等條件。 詳文獻(xiàn)中說明: MnCeOx catalysts with Mn/Ce atomic ratio (i.e., x/y) ranging between 1/3 and 3/1 were prepared via the redox-precipitation route, consisting in the titration at constant pH (8.0 0.2 by addition of KOH) of the KMnO4 precursor with a solution of Ce3+ and Mn2+ nitrates [7,16,17]. After titration, catalysts were filtered, washed, dried at 373 K (16 h) and further calcined (6 h) in air at 673 K (MxCy-R4). An aliquot of the M1C1-R sample was used in the dried form (M1C1-R), while another one was calcined at 873 K (M1C1-R6). Moreover, the influence of the alkaline agent was evaluated using LiOH (M1C1-R4L) and NH4OH (M1C1-R4N) instead of KOH for the synthesis of M1C1-R4 samples. A MnCeOx sample with Mn/Ce equal to 1, prepared via co-precipitation of MnCl2 and CeCl3 (M1C1-P4) precursors, was taken as reference [10,15–17]. The list of catalysts with the relative notation and main physico-chemical properties is given in Table 1. |
