摘要: Immobilization of photocatalytic powder is crucial to obtain industrially relevant purification processes. To achieve this goal, self-supporting TiO2 foams were manufactured by a polyacrylamide gel process. These gels calcined at different temperatures study the effect calcination temperature on foam characteristics (rigidity, crystallinity, and porosity) its influence activity. The results show that an optimal degradation achieved for those between 700 800°C. Calcination higher in steep decrease activity, explained stability issues material due formation Na2SO4 phases larger rutile fraction.
