The speed of formaldehyde decomposition has been studied using catalysts (vanadium nanoparticles, nano vanadium oxide with nano hydroxyapatite and vanadium oxide). The catalysts have been made with three different concentrations (100, 500 and 1000) ppm and at three different temperatures (25, 50 and 75) ° C. X-ray diffraction (XRD) and transmission electron microscope (TEM) images were used to study the structural and engineering properties of the prepared catalysts, which were nanostructured materials. The increase in the concentration of the catalysts and the temperature led to increasing the chemical reactions rate. However, it decreased the activation energy, which was calculated using the Arrhenius equation. The catalyst NV2O5 showed a better reaction rate compared to other prepared catalysts 100.1 x 〖10〗^(-3) and 112.5 x 〖10〗^(-3) ) for the catalysts such as nano vanadium oxide and nano vanadium oxide with nano hydroxyapatite, respectively
