La_1-xZr_xNiO₃ perovskite nanocatalysts were synthesized by citrate sol-gel method. The synthesized samples were characterized by using X-ray diffraction (XRD), temperature programmed reduction (TPR), and inductively coupled plasma (ICP) techniques. Surface areas of the compounds were measured by BET method. Morphology study of the nanocatalysts was performed using scanning electron microscopy. The XRD patterns confirmed a well-crystallized structure in doping level up to 0.2 for La_1-xZr_xNiO₃. The SEM images showed that the synthesized particles were in nanoscale. The TPR analysis revealed that by increasing the amount of Zr inthe preparedsamples, reduction process became difficult. The catalytic activity of the nanocatalysts was studied in dry reforming of methane (DRM) with CO₂and the H₂/CO ratio~1 was reported when doping level was 0.1.
