Abstract	Abstract: ZnO nanoparticles are capable of enhancing the physical abilities of different materials due to its many properties, including their photocatalytic and antibacterial activity and their UV protection. In this work, ZnO nanoparticles were synthesized by the Pechini method, varying the calcination time and temperature. These nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron miscroscopy (TEM), and Fourier transform infrared spectroscopy (FTIR). In every synthesis process ZnO in the zincite form was obtained, with a minimum effective diameter of about 23 nm, for a process with calcination at 700°C for 3 h. Correlation coefficients greater than 0,98 were obtained for all syntheses, by comparing the FTIR spectrum against a ZnO commercial sample. Resumen: Las nanoparticulas de ZnO son capaces de potenciar las capacidades fisicas de diversos materiales por sus numerosas propiedades, entre las que destacan su actividad fotocatalitica, antimicrobiana y de proteccion UV. En este trabajo se sintetizaron nanoparticulas de ZnO por el metodo de Pechini variando el tiempo y la temperatura de calcinacion. Estas nanoparticulas fueron caracterizadas a traves de difraccion de rayos X (DRX), microscopia electronica de barrido (MEB), microscopia electronica de transmision (TEM) y espectrometria infrarroja con transformada de Fourier (FTIR). En todas las sintesis se obtuvo ZnO en forma de zincita, y con un diametro efectivo minimo de aproximadamente 23 nm, para la calcinacion a 700°C durante 3 h. Se obtuvieron coeficientes de correlacion mayores a 0,98 para todas las sintesis, al comparar el espectro FTIR con el de una muestra comercial de ZnO.
