“…In the absence of catalyst, the conversion of benzyl alcohol is lower than 1%.E ncouragingly,w ith the addition of the holey lamellar HEO catalyst, the catalytic conversion increases exponentially with increasing reaction temperature from 100 8 8Ct o1 20 8 8C( Supporting Information, Table S2), and up to 98 %c onversion can be achieved after reaction at 120 8 8Cf or only 2hunder solventfree atmospheric conditions.T ot he best of our knowledge, this is the highest reported conversion among previous reported single-atom, cluster,noble-metal, and alloy catalysts (Figure 2b;Supporting Information, Table S3). [26][27][28][29][30][31][32][33] It should be pointed out that the reported TOFn umbers were calculated on the basis of loading amount of noble metals (loading rate = 0.5-5 wt %), and the metal oxides just act as supports,n ot catalytic active materials.H owever,n oble metals do not exist in this catalytic system, and the TOF value can only be calculated to be 994 in terms of the amount of HEO.A u/Pd-TiO 2 catalyst, whose conversion is 91.6 %i n 8hunder 0.2 MPa of O 2 ,i st he most advanced catalyst ever reported. [26] Compared with Au/Pd-TiO 2 catalyst, the holey lamellar HEO catalyst not only works at atmospheric pressure,b ut also reaches the equilibrium of the catalytic reaction in less time.T here are three products in this oxidation process:b enzaldehyde,b enzoic acid, and benzyl benzoate.B enzoic acid is the dominant product in the catalytic reaction, benzaldehyde and benzyl benzoate are identified as the major byproducts.Inthe reaction process,the benzyl benzoate is formed by the esterification of benzyl alcohol with benzoic acid.…”
