TiO₂/LaFeO₃ Composites for the Efficient Degradation of Benzoic Acid and Hydrogen Production.

ABSTRACT: LaFeO₃/TiO₂ composites were prepared in the range 0-12.2 wt% of LaFeO₃, characterized, and tested for both benzoic acid (BA) and 4-methoxycinnamic acid (MCA) degradation in aqueous solution, and hydrogen evolution. The preparation method was via ball-milling without thermal treatment. The composite materials presented agglomerates of LaFeO₃ with an average size from 1 to 5 μm, and the TiO₂ powder was well dispersed onto the surface of each sample. They showed varying activities for BA degradation depending on composition and light wavelength. The 6.2 wt% and 12.2 wt%-LaFeO₃/TiO₂ composites exhibited the highest activity under 380-800 nm light and could degrade BA in 300 min at BA concentration 13.4 mg L^-1
