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.展开更多
