Sol-gel boria-alumina mixed oxides with a wide range of B / Al atomic compositions have been characterized as dried xerogels in the preceding paper in which a structural model with four domains of composition was proposed. The present paper presents

While boria-alumina mixed oxides have been widely used for various catalytic reactions, their structure has never been satisfactory elucidated and is still a matter of debates. The present paper deals with the elucidation of the structure of boria-al

Vanadium–cerium oxide samples with different V/Ce atomic ratios were prepared using the impregnation method, and then calcined under air at 773 K, and characterized by XRD and 51V MAS NMR. Ceria is the only phase evidenced in low vanadium content s

Boria–alumina mixed oxides were synthesized by the sol-gel method. MAS-NMR spectroscopy spectra exhibited two boron species, BO 3 and BO 4 , the former giving an important second order quadrupolar effect. Then, spectra were interpreted with a simul
