| Reduced Graphene oxide supported Titanium dioxide nanomaterials for the photocatalysis with long cycling life Original Research Article Applied Surface Science, Available online 7 August 2015, Pages Yuan-Cheng Cao, Zhongtian Fu, Wenjun Wei, Linling Zou, Tie Mi, Dan He, Chaolu Yan, Xiyou Liu, Ying Zhu, Liuqing Chen, Yuanjie Sun
Graphical abstractThe reduced Graphene Oxide (rGO) supported TiO2 (rGO/TiO2) as the photocatalyst was synthesized and evaluated. BET surface area showed 62.4 m2/g for TiO2 and 247.3 m2/g for rGO@TiO2. Size distribution showed when the rGO ratio increases from 5% to 15% (rGO/TiO2), and the resultant rGO@TiO2 samples show better size distribution in the range of 100nm to 200nm. Photocatalysis test showed when the exposure time increased to over 100minutes, the degradation rate for rGO@TiO2 could reach to 96.4%. Reproducibility test showed the rGO@TiO2 photocatalyst can keep the degradation rates at less for 25 cycles.
 | Electrochemical Imunnosensor for Enterobacter sakazakii detection based on electrochemically reduced graphene oxide -Gold nanoparticles/ionic liquid modified electrode Original Research Article Journal of Electroanalytical Chemistry, Available online 7 August 2015, Pages Xue Hu, Wenchao Dou, Guangying Zhao
Graphical abstractThe conductivity of the electrode was promoted by the electrodeposition of graphene oxide and HAuCl4, and the sensitivity of the immunosensor was enhanced and strengthened. The binding capacity and biocompatibility of ERGO-Au modified electrode was elevated greatly by the iLs film. The proposed enzyme immunosensor had high sensitivity, good specificity, acceptable accuracy and reproducibility, and low detection limit characteristics and could be a promising analytical tool in detection of E. sakazakii in practical samples.
