compounds [ 4 ]. Analytical technology allows for an increasing number of PPCPs to be detected in STP effluents, surface water, ground water, drinking water, sludge, soil and aquatic organisms [ 5 – 8 ]. According to literature reports, the
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
components of the oil and separated fractions were identified by comparison of their linear retention indices, determined in relation to a homologous series of n -alkanes, with those from pure standards or reported in the literature. Comparison of
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
binding energies of Ru species (3d 5/2 ) found in the literature and this study BE of Ru 3d 5/2 (eV
decreases with the increasing Si/Ti ratio, indicating that the Lewis acidic sites in samples are mainly from the highly-dispersed amorphous TiO x species. The results are consistent with the finding reported in the literature [ 24
