Abstract Properties of a solid acid carbon coating prepared on TiO2 powder surface using photochemical vapordeposition (photo-CVD) were evaluated. The TiO2 powder surface became brown during UV illuminationunder a flowing xylene and xylene sulfonic acid mixture. Observation by TEM revealed an amorphouscarbon coating on the TiO2 powder. Sulfonate groups were identified on the coating using FT-IR. A chartof NH3-TPD measurements showed two peaks: that at high temperature was attributed to the coating’sstrong acid. The carbon coating’s acidity was equivalent to that of the solid superacid carbon powder andthe carbon-coated TiO2 decomposed cellulose.
