AB  - Well-crystalline ZnO nanoparticles (NPs) were synthesized in large-quantity via 
      simple hydrothermal process using the aqueous mixtures of zinc chloride and 
      ammonium hydroxide. The detailed structural properties were examined using X-ray 
      diffraction pattern (XRD) and field emission scanning electron microscope (FESEM) 
      which revealed that the synthesized NPs are well-crystalline and possessing 
      wurtzite hexagonal phase. The NPs are almost spherical shape with the average 
      diameters of  approximately  50 +/- 10 nm. The quality and composition of the synthesized NPs 
      were obtained using Fourier transform infrared (FTIR) and electron dispersed 
      spectroscopy (EDS) which confirmed that the obtained NPs are pure ZnO and made 
      with almost 1:1 stoichiometry of zinc and oxygen, respectively. The optical 
      properties of ZnO NPs were investigated by UV-vis absorption spectroscopy. 
      Synthesized ZnO NPs were extensively applied as a photocatalyst for the 
      degradation of acridine orange (AO) and as a chemi-sensor for the electrochemical 
      sensing of acetone in liquid phase. Almost complete degradation of AO has taken 
      place after 80 min of irradiation time. The fabricated acetone sensor based on 
      ZnO NPs exhibits good sensitivity ( approximately  0.14065 muA cm(-2) mM(-1)) with lower 
      detection limit (0.068 +/- 0.01 mM) in short response time (10s).
