dc.description.abstractMetal and metal oxide nanoparticles (NPs) are promising agents for reducing energy consumption and pollution in applications where combustion power generation is provided. This study focuses on the production of new generation perovskite-type metal oxide NPs with enhanced catalytic activity customized for combustion and investigation of their catalytic performance for gasoline. The droplet scale combustion experiments were carried out at ambient temperature, atmospheric pressure and under normal gravity, the experimental processes were recorded with an optical system consisting of a high-speed camera and a thermal camera with a spectral range of 7.5–14 ?m, and the combustion and atomization behavior of the nanofuel droplets were characterized. Perovskite-type NPs were produced by sol-gel technique in varying stoichiometric ratios (LaMnO3, La1- XNdXMnO3, La1-XBaXMnO3, Nd1-XBaXMnO3, La0.5NdXBa0.5-XMnO3, x = 0, 0.3) to confirm their catalytic activity’s effect on gasoline droplets’ combustion behavior. Structural characterization of the obtained five different NPs was carried out by SEM and XRD techniques. Chemical analysis, surface area measurements, and spectral properties of the samples were determined by XPS, BET, and UV–Vis spectroscopy, respectively. The results showed that all perovskite-type NPs have particle size range of 25–40 nm. La0.7Nd0.3MnO3 NPs had the highest oxygen adsorption ability and La0.5Nd0.3Ba0.2MnO3 NPs had the largest surface area (393.4898 m2 /g). Perovskite type NPs tended to increase ignition delay and extinction times. The maximum flame temperature of fuel droplets loaded with La0.5Nd0.3Ba0.2MnO3 NPs was 469 ?C. This temperature was 274 ?C higher than the maximum flame temperature of the pure gasoline droplet. The outcomes demonstrated that, with the right catalyst design, perovskite-type NPs can perform better as powerful oxidizers and high energy combustion catalysts.
