Nano g-C3N4/TiO2 composite was synthetized and utilized as a novel photocatalyst for enhanced photochemical vapor generation for sample introduction to atomic fluorescence spectrometry. High reduction efficiency for Se (VI) was obtained to facilitate its ultrasensitive determination by atomic fluorescence spectrometry, with a limit of detection of 0.08 ng mL(-1). The photocatalytic mechanism of this composite was also discussed and demonstrated its highly efficient photocatalytic capacity and promissing applications in trace selenium (VI) determination and extraction.
