• organosilsesquioxane (O1.5Si–R–O1.5). These hybrids are usually prepared by conventional sol–gel processing, i.e., by hydrolysis and condensation of alkoxysilane precursors, which offers an excellent control over composition and homogeneity, while texture can be tuned using various templating approaches [9]. In the

Keywords: ceria; CO oxidation; graphene oxide; sol–gel processing; Introduction Ceria (CeO2) has been widely studied as catalyst or catalyst support for redox reactions owing to its high oxygen storage and release

• by sol–gel processing of cerium tert-butoxide, in ethanol as solvent [17] contain reduced graphene oxide (rGO)-like structures. The appearance of rGO-like structures can be associated with cerium tert-butoxide (or possibly cerium alkoxides in general) as precursor and ethanol as solvothermal solvent

• , and may also explain the higher catalytic activity (compared with, for example hydrothermally treated samples). This was also confirmed by introduction of “external” graphene oxide during sol–gel processing, by which the rGO structures and the catalytic activity were enhanced. The previously observed

• the application of diol/polyol-modified silanes [1][2][3][14][15][16][17][18]. Nakanishi and Lindén relied on polymerization-induced phase separation during sol–gel processing to form monolithic bodies with a hierarchical organisation of the pore structure at the meso- and macroscopic length scale [16
