Influence of the Pyrolysis Temperature and TiO-Incorporation on the Properties of SiOC/SiC Composites for Efficient Wastewater Treatment Applications.

This study focuses on the development of porous ceramer and SiOC composites which are suitable for microfiltration applications, using a mixture of polysiloxanes as the preceramic precursor. The properties of the membranes-such as their pore size, hydrophilicity, specific surface area, and mechanical resistance-were tailored in a one-step process, according to the choice of pyrolysis temperatures (600-1000 °C) and the incorporation of micro- (SiC) and nanofillers (TiO). Lower pyrolysis temperatures (<700 °C) allowed the incorporation of TiO in its photocatalytically active anatase phase, enabling the study of its photocatalytic decomposition.
