Abstract


The instantaneous formation of mechanically stable cerium vanadium oxide gels starting from soluble polyoxovanadates is reported together with initial application studies. Upon addition of phosphoric acid to solutions containing a vanadium oxide source (e.g. (nBu(4)N)(4)[V4O12]) and Ce3+, instantaneous formation (reaction time <1 s) of a vanadium oxide gel is observed. The gel shows unique mechanical and thermal stabilities (up to similar to 180 degrees C). High permeability of the gel is observed, allowing its use for long-term acid delivery into aqueous media or for the adsorption of organic aromatic dye pollutants from solution. A range of spectroscopy and electron microscopy techniques provide insight into the gel formation and the gel composition: an intertwined 3D matrix of nanowires (d similar to 10 nm) containing cerium, vanadium oxide and phosphate is identified as an inorganic matrix which enables the formation of the mechanically stable gel.
