interpretation of the phenol formation in the literature [ 12 , 16 ] is ambiguous and two possible routes are suggested—directly from cyclohexanol (direct route) and through dehydrogenation of cyclohexanone (consecutive route). We assume that the consecutive
were identical to those reported in the literature [ 23 ]. After RE and Pt loadings, the samples maintained the crystalline structure (diffraction patterns not shown), although a small decrease in peak intensity is detected. The RE and Pt contents are
reaction rate laws, derived from the most plausible reaction mechanisms suggested in the literature, were tested using the kinetic data generated under differential reactor conditions. The extent of agreement between the experimental and model predicted
binding energies of Co 2 p 3/2 for all the catalysts are given in Table 1 , followed by the literature data of various Co-containing compounds in Table 2 . The binding energy of Co 2 p 3/2 for CoNT was 780.1 eV, which could be matched with that of CoO
method provides high selectivity and yields of m -PDA at low cost. Although limited information is available in the literature on the kinetics of the hydrogenation of m -dinitrobenzene, it is reasonable to assume that m -dinitrobenzene behaves
regarding the disposal of the large excess of mixed acids and generating nitrogen oxide (NO x ) fumes apart from added expense. A variety of heterogeneous catalytic nitration methods in which sulfuric acid is not used are described in the literature
, charge and coverage of the surface, and correspondingly the apparent relative dielectric constant of the surface layer, including the adsorbed phase. Studies of SnO 2 /γ-Al 2 O 3 systems are infrequent in the literature and mostly in connection
procedure described in the literature [ 14 ]. Titania was incorporated on the silicas following the procedure described in our previous papers [ 5 , 7 , 8 ]. The composition was 4SiO 2 : 1HTABr: 1Na 2 O: 0.15(NH 4 ) 2 O: 350H 2 O. The silicas were
catalyst, the surface area of Ni/C 16 –MoS 2 , in was higher than that of Ni/C 16 –MoS 2 , showing that the activation mode produced different effect on the morphology of the samples. The result was in agreement with the literature [ 9 ] and the in situ
(atmospheric pressure and 100 °C) than reported in the literature [ 4 – 12 ] with a view to analyze the adsorbed species formed in the first step of the phenol adsorption-oxidation on the Mn–Ce catalyst by DRIFTS spectroscopy. Experimental
