ABSTRACT: The simultaneous photocatalytic production of hydrogen
and degradation of naphthalene in seawater was successfully achieved using
carbon modified titanium oxide (CM-n-TiO2) nanoparticles under
natural sunlight illumination. Compared to unmodified titanium oxide (n-TiO2),
CM-n-TiO2 nanoparticles exhibited significantly higher photocatalytic
efficiency. It is considered that carbon modification is responsible for the
significant enhancement in the observed photoactivity. The experimental results
indicated that the simultaneous production of hydrogen and degradation of
naphthalene was favorable at pH 8 and optimal catalyst dose of 1.0 g.L-1.
The solar photocatalytic degradation of naphthalene in seawater using CM-n-TiO2 successfully fitted using Langmuir-Hinshelwood model, and can be described by
pseudo-first order kinetic model.
