The present article reports the synthesis of silver nanoparticles in silica aerogel matrix by sub-critical drying technique. The catalytic performance of these nanocomposites was evaluated for the selective oxidation of benzene. Silica aerogel with 1, 5, 10 and 25 wt.% of silver was prepared and characterized for their physicochemical characteristics. The catalytic performance of these samples was evaluated as a function of silver particle size crystallized within the aerogel matrix. The sample with the silver concentration of 1 wt.% showed high selectivity among the tested samples. With increasing silver particle size, the % conversion increased with a decreased selectivity, which is attributed to the particle size effect on the catalytic oxidation of benzene.

“…However, the oxidant H 2 O 2 has some serious drawbacks, such as expensive, inherently corrosive, easily decomposable and especially, in high concentrations, is prone to be lower selectivity etc. Thus, for a long time much attention has been paid to the direct hydroxylation of benzene by O 2 (air) with the assistance of H 2 [8][9][10], CO [11] or ascorbate [12,13] and transitionmetal catalyst, such as Cu, Pd, or Pt. Nevertheless, there is a potential risk of explosion when H 2 (CO) and O 2 are fed simultaneously and ascorbate as a consumptive reagent might be costly.…”

A coupled process, of which Pd/c-Al 2 O 3 -NH 4 VO 3 catalyzed the hydroxylation of benzene with hydrogen peroxide produced in situ by an anthraquinone (AQ) redox route, was carried out via a sealed gaseous inner-circulated device under the atmospheric pressure. By means of such process, 0.57% of benzene conversion, 100% of phenol selectivity and 26.6% of anthraquinoneutilized efficiency were achieved upon the mixed Pd/cAl 2 O 3 -NH 4 VO 3 (V/Pd molar ratio for 4) in the presence of benzene/acetic acid (4v/10v). Above all, after the coupled reaction system was recycled three times, the accumulated phenol amount could achieve ca. 0.833 mmol and its average value (ca. 0.278 mmol) was slightly higher than phenol amount obtained in the first run (ca. 0.255 mmol), indicating that such coupled reaction system could be recycled efficiently. In addition, a synergistic mechanism was proposed to explain the favorable effect of V compound on the Pd/c-Al 2 O 3 catalyst.
