Application of nanoparticles are used in many different fields, such as transportation, cosmetics, pharmaceuticals, airplanes. Many nano-particles of lanthanum, such as LaF3, La (CO3)3, and La2O3, have been synthesized [1]. Lanthanum compounds are widely used in carbon bulbs and projectors. Lanthanum oxide using to make optical fiber and various alloy. Catalyst is a substance that increases speed of a chemical reaction. The goal of chemists is to produce high-activity catalytic activity, complete selectivity. The heterocyclic compounds are a major contributor to the major pharmaceutical, veterinary, and chemical compounds [2]. Heterocyclic compounds are found in many fossil fuels, which has been a source of concern for environmental pollution. In this project first we synthesized La2O3 nano-particles and characterized using FT-IR, XRD, SEM and VSM techniques. Then nano-particle applied as catalyst for synthesize of Quinoxalin.
