Synthesis and characterisation of xTiO_2 centre dot (1-x)SiO_2 - carbon composites

摘要

A series of xTiO_2 centre dot (1-x)SiO_2-carbon xerogels (0.00.4, however, anatase was observed. The surface acidity increased for the composites as compared to the blank. The acid strength was higher and the distribution of surface acidity was wider for the composites with a high titania content, whereas surface acid sites were weaker for the sample containing only this metal oxide as inorganic phase.
