Graphite/C-doped TiO2 composite was synthesized through a modified sol–gel reaction. DRS resultsindicated that light absorbance edge of graphite/C-doped TiO2 was clearly red-shifted to visible lightregion by doping with C. SPS results displayed that separation efficiency of photoinduced charge carriersof graphite/C-doped TiO2 were greatly increased by coupling with graphite. Moreover, the photocatalyticperformance of composite was evaluated by the degradation of methyl orange (MO). Results showedthat graphite/C-doped TiO2 exhibited higher photocatalytic activity for MO than that of pristine TiO2 andP25, which was mainly attributed to the high crystallization, large surface hydroxyl groups, intensevisible light absorption and effective separation of photoinduced charge carriers.

A multiplex real-time PCR method fordiscriminating deer and common domestic species,including cattle, goat, horse, donkey, pig, and chicken wasdeveloped. Species-specific primer pairs were designedand used to produce different size DNA fragments withdiverse melting temperature (Tm) values. The specificityand sensitivity of these primer pairs were separatelyconfirmed using simplex real-time PCR analysis. Multiplexreal-time PCR analysis was performed using combinedprimers, yielding distinct melting curve profiles for eachspecies. The sensitivity limit of the multiplex PCR methodwas evaluated. Trace DNA of other species in deer DNAcould be identified. Common deer products, includingblood, meat, and antler were tested using this multiplexPCR method and different species of deer and domesticanimals were identified. The rapid multiplex real-time PCRassay described herein is a specific, sensitive, and reliablemethod for high-throughput authentication of deer anddomestic animal products.

Effects of hydrothermal parameters on morphology, crystal structure, light absorption, separation efficiencyof photo-generated charge carriers, and photocatalytic removal of Bisphenol A (BPA) of Ti-basedTiO2 nanomaterials were systematically investigated. Through changing hydrothermal parameters,TiO2 nanobelts, TiO2 nanosheets and TiO2 nanowires were prepared. With increasing NaOH concentration,hydrothermal temperature, and hydrothermal time, more TiO2 with (101) crystal plane grew onTi substrate, resulting in higher crystallinity. The UV-light absorption enhanced with increasing NaOHconcentration, but decreased with improving hydrothermal temperature, hydrothermal time, and HClconcentration. Variation of UV-light absorption was mainly affected by morphology, and UV-light absorptionof TiO2 nanomaterials with different morphologies was arranged in order ofnanobelts > nanosheets > nanowires. The hydrothermal growth of TiO2 nanomaterials on Ti plate conformedto Ostwald ripening mechanism. Variation trend of photo-generated current was consistent withthat of BPA degradation, they both first increased and then decreased within investigated range. The optimalNaOH concentration, hydrothermal temperature, hydrothermal time, and HCl washing concentrationwere 1 M, 170℃, 28 h, and 0.1 M, respectively. Under this condition, Ti-based TiO2 nanosheets exhibitedthe highest BPA removal efficiency (92.7%), which was due to highly ordered nanosheet structure, goodcrystallinity, appropriate UV-light absorption and high separation efficiency of electron-hole pairs.
