Graphical abstractWe synthesized the flower-like SnO2 microspheres and SnO2-graphene (S–G) composites with different GN contents through a simple one-pot hydrothermal method. The S–G composite with optimum GN contents exhibits the highest H2 sensing response of 87.2 at 150°C, which is about 70 times higher than that of pure SnO2.

Graphical abstractTaking advantage of the unique plane structure of the functionalized graphene, Au microclusters (AuCMs) was successfully electrodeposited on the surface of sulfonate functionalized graphene (SF-GR) and AuCMs/SF-GR/GCE was constructed and thoroughly characterized. The prepared electrode was applied to the independent determination of GA in black tea and cortex moutan as well as the simultaneous determination of GA and UA in urine samples. The AuCMs/SF-GR/GCE exhibited a variety of advantages such as uniqueness, high anti-interference ability, low detection limit and wide linearity range, and significantly enhanced the anodic peak currents of GA and UA. Meanwhile, the spiked results determined by AuCMs/SF-GR/GCE were compared to the results detected by HPLC. With high sensitivity and selectivity, good reproducibility, low solvent consumption and without time-consuming sample pretreatment, the electrochemical method is easier, faster and reliable. Therefore, the novel sensors constructed was applicable to simultaneous determine GA and UA in human urine samples and respective detect GA in black tea, cortex moutan samples.
