楼主翻译的是这篇文献吧：Optimization of the MnCeOx system for the catalytic wet oxidation
of phenol with oxygen (CWAO)
其中MxCy-R4就是一个样品的编号。
x/y是Mn/Ce的比例。 R4，R6等是不同的干燥和煅烧等条件。
详文献中说明：
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. |
