Cataluminescence sensing of carbon disulfide based on CeO2 hierarchical hollow microspheres

Material morphology-dependent cataluminescence (CTL) sensing characteristic and application are presented in this work. Hierarchical hollow microspheres CeO 2 were synthesized via the hydrothermal reaction of glucose and N, N -dimethyl-formamide (Glu-DMF). SEM, XRD, TEM, HRTEM and BET were used to characterize the prepared CeO 2 materials. Compared with CeO 2 cubics (CeO 2 Cubs), CeO 2 hierarchical hollow microspheres (CeO 2 HMs) show an enhanced CTL response to carbon disulfide. The response and recovery times of CeO 2 HMs-based CTL sensor towards carbon disulfide are about 8 s and 20 s, respectively. CeO 2 HMs exhibits a linear CTL response to carbon disulfide in the concentration range of 0.50~10 μg•mL -1 with an excellent sensitivity and selectivity. These results suggest that CeO 2 HMs will be a highly promising CTL sensing material for the detection and monitoring carbon disulfide. CeO 2 hierarchical hollow microspheres (CeO 2 HMs) were synthesized via the hydrothermal reaction of glucose and N, N-dimethyl -formamide (Glu-DMF). Meanwhile, the prepared CeO 2 HMs shows commendable CTL response towards carbon disulfide. Due to the excellent analytical performance of designed CeO 2 HMs-based sensor for carbon disulfide, it has potential application value in various locations
