Abstract |
: |
ZnO nanocapsules have been synthesized hydrothermally. The structural and morophological properties were investigated using X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), FTIR, Raman, EDS and UV-vis absorption spectroscopy. For the first time chemical sensing properties of the synthesized ZnO nanocapsules have been investigated by I-V technique, where chloroform is used as a target compound. The chloroform sensors show good sensitivity (0.478 μA cm -2 mM -1), lower detection limit (6.67 μM), and large linear dynamic range (LDR, 12.0 μM-12.0 mM) with good linearity (R, 0.8523) in short response time. Additionally, photocatalytic activity of the prepared capsule shaped ZnO photocatalyst was evaluated by the degradation of acridine orange. Prepared ZnO nanocapsules posses high photocatalytic activity when compared with TiO 2-UV100. |
