Abstract:
Selective detection of volatile organic compound is crucial for medical applications. Here, we have synthesized fullerene (C 60 )-MoSe2(F-MoSe2) composite for selective detection of formaldehyde at room temperature. MoSe2 nanoflowers were synthesized by hydrothermal method and further functionalized with 0.05 wt% of fullerene solution. The nanocomposite was characterized with different characterization tools. The VOC sensing measurements revealed the natural selectivity of the F-MoSe2 sensor towards formaldehyde compared to other different VOCs with a significant response of 35% for 50 ppm at room temperature. Moreover, formaldehyde selective behavior was possible due to improved surface area and highly oxygen-functionalized surface after fullerene modification.
