“…To our knowledge, no comparative research has been reported for catalytic ozonation of Fluoxetine antidepressant drug in aquatic systems by nanosized boehmite and γ-alumina catalysts. Particularly, γ-alumina and boehmite are promising for catalytic and adsorption processes and have a large surface area (Kiadehi and Taghizadeh 2018;Kiadehi et al 2017). In the present work, at first, co-precipitation was used to synthesize nanosized boehmite and γ-alumina powders.…”

Degradation of the Fluoxetine, as commonly used antidepressant pharmaceutical, from aqueous media with different oxidation processes including ozonation and catalytic ozonation (in the presence of nano-boehmite and nano-γ-alumina) was studied in a batch reactor. The catalysts were synthesized via the co-precipitation route. Then, kinetic study of catalytic ozonation process for elimination of Fluoxetine in water was performed. The kinetic of the degradation process was properly fitted to the pseudo first-order equation. The influence of operational parameters, such as pH of solution, scavenger compound (tertbutyl alcohol) and two-type anions (phosphate and nitrate), on Fluoxetine degradation efficiency was studied. The influence of water pH presented that hydroxyl groups of surface are considered as the major active site in the catalytic ozonation of Fluoxetine for the • OH radical production in water for nano-boehmite but not for nano-γ-alumina. It was found that the Fluoxetine removal efficiency remarkably increased for catalytic ozonation in comparison with ozonation process in a batch reactor at pH 7. Finally, two-reaction mechanisms were offered for catalytic ozonation of Fluoxetine in aqueous medium by boehmite and γ-alumina nanocatalysts.

“…The γ-alumina support has a great specific area, well-defined distribution of pore sizes and stability over a wide range of temperatures. 58 However, it was found that the performance of the Al 2 O 3 supported catalyst was similar to the carbon-supported catalyst. Hence, we chose to investigate the effect of various Pt loading supported on Al 2 O 3 .…”

“…Notably, EG can be produced by hydrogenolysis of biomass-derived polyols and alternatively by hydration of petrochemically derived ethylene oxide, depolymerization of poly(ethylene terephthalate) (PET), and so on . Hydrogen production from EG via steam reforming has been explored over Ru/Al 2 O 3 , Ni/CeO 2 -Al 2 O 3 , Rh or Ni/MgAl 2 O 4 , Pt or Ni/γ-Al 2 O 3 , Ni-Pt/Al 2 O 3 , Ni-Cu/La 2 O 3 -MgO, Ni/attapulgite, and others. Compared to the steam reforming process, which works at a high temperature (>200 °C), aqueous-phase reforming is getting a lot of recognition for hydrogen production from biomass-derived oxygenated compounds at a relatively lower temperature (<200 °C) .…”

We developed an efficient process for producing hydrogen gas from aqueous ethylene glycol (EG) at 90−160 °C over a ruthenium catalyst. We achieved a high yield of hydrogen gas (up to 3.0 n(H 2 )/n(EG)) and formic acid (85% yield) from ethylene glycol in aqueous alkaline medium at 110 °C, where the role of reaction temperature and base concentration was found to be critical in achieving a high yield of H 2 . The chemical and morphological properties of the synthesized ruthenium catalyst were established using P-XRD, TEM, XPS, and other techniques. Advantageously, the ruthenium catalyst exhibited appreciably high long-term stability for over 70 h, generating ca. 290 L of H 2 per gram of Ru with a yield of 1035 L of H 2 per L of ethylene glycol.
