Snβ -zeolite was sucessfully synthesized by direct immobilization of SnCl2 on high silica commercial β-zeolite (1700 Si/Al) with the assistance of Choline chloride (ChCl) in aqueous solution. The method facilitated the dispersion of tin through SnCl/ChCl complex formation and reduced the generation of inactive tin oxides species on β-zeolite as indicated by the good solubility of SnCl2, XRD, UV-VIS diffuse reflectance and electronic microscopy measurements. ChCl also had effect on dealumination which led tin to get into the framework of β-zeolite with the calcination as indicated by NH3-TPD, and UV-VIS spectroscopy. The catalyst with 1.3 wt% Sn loading amount was proved to be active and selective for the sugars isomerization, trioses conversion into lactates and glycolic acid formation from glyoxal.
