Cataluminescence sensing of carbon disulfide based on CeO hierarchical hollow microspheres.

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