This study investigates the oxidation of 1,3-butadiene (BD), which is a classified hazardous air pollutant with high degree toxicity, over temperature range 300–650 °C. The intent in this work to find an efficient method destroying toxic, carcinogenic, and unstable BD, can cause storage problems as well and, process, exploring possibility its conversion useful industrial starting materials, such synthesis gas. being unsaturated hydrocarbon, reactive right combination heterogeneous catalysts. For purpose, we investigate role Ni- Cu-based catalysts different loadings on alumina, niobia, ceria–niobia combinations track yield selectivity obtained products product relative yields were through gas chromatography (GC) combined mass spectrometry thermal conductivity detector, while Fourier transform infrared spectroscopy (FTIR) also used corroborate GC results. main objective was identify best catalyst for BD low-mid range. Furthermore, order dispersion, morphology, metal–support interactions, surface areas, pore sizes, redox capabilities their potential influence reaction, comprehensive characterization methods X-ray diffraction, FTIR, scanning electron microscopy energy-dispersive spectra, nitrogen adsorption desorption, hydrogen-temperature-programmed reduction employed. It seen that 10% copper loading CeO2 Nb2O5 showed optimal catalytic performance 100% butadiene highest at all temperatures. findings entail practical environmental application reactions dealing toxic compounds constituents hydrocarbon emissions from exhaust catalysis.
