Zinc oxide (ZnO) nanoparticles have been modified using caprylic acid and n-butylamine as surface modifiers through in situ surface modification under mild hydrothermal conditions (T=150-250 degrees C; P=autogenous). The surface modification was carried out using different molar concentrations of ZnO (1-4M) in the starting materials with an acidic mineraliser like 1 N HCl. The resultant products obtained were either hydrophobic or hydrophilic depending upon the surface modifier used. The ZnO nanoparticles synthesised were subjected to a systematic characterisation using powder X-ray diffraction, Fourier transform infrared spectroscopy, SEM, ultravioletvisible spectroscopy and photocatalytic degradation studies. The hydrophilic ZnO was used in the photocatalytic degradation of indigo carmine dye, and it shows 98% efficiency with a residence time of 4 h.
