“…The need for ignition or calcination step at higher temperatures with an increase in fuel content limits the available surface area and other surface properties of the synthesized materials. Hence, the SCS of metal oxide powders demands optimized fuel amount and combustion conditions with limited control over the surface properties of the synthesized materials 34 . Mixed‐fuel approach and template‐assisted synthesis are the two promising strategies for the controlled combustion synthesis of metal oxide powders with tunable surface properties 27,35‐37 .…”

“…Mixed‐fuel approach and template‐assisted synthesis are the two promising strategies for the controlled combustion synthesis of metal oxide powders with tunable surface properties 27,35‐37 . Several studies have explored the effect of mixture of fuels on the combustion characteristics and the properties of synthesized materials and found that mixture of fuels approach can be used to control and enhance certain characteristics of the combustion‐synthesized materials 31,34,36,38 . In mixed‐fuel approach, the soluble fuel can chelate and form a complex with the metal ions and regarded as a primary fuel and the fuel with a templating role generally regarded as a secondary fuel.…”

In this work, nanosized zinc oxide (ZnO) powders were fabricated by urea–nitrate solution combustion synthesis using activated carbon as a structure‐directing template and secondary fuel at different fuel–oxidant ratios. The as‐synthesized powders were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption–desorption measurements, UV–Vis diffuse reflectance spectroscopy, and photoluminescence. The effect of fuel amount on photocatalytic activity of ZnO powders was evaluated by the degradation of an azo dye Orange G. It was observed that combustion synthesis with activated carbon as a secondary fuel had a profound effect on reducing crystallite size and enhancement of specific surface area. The crystallite size of the as‐synthesized powders varied from 46 to 26 nm. The ZnO powder prepared at a fuel–oxidant ratio of 1.8 possessed the small crystallite size and high specific surface area of 69 m2/g. It correspondingly resulted in the highest dye removal percentage of 99% with a rate constant of 0.027 min−1. The improvement in dye degradation can be due to the synergistic interaction and interplay of enhanced surface area and catalytic ability of the photocatalyst. This study provides a simple single‐step synthesis methodology to produce metal oxide nanopowders with tunable surface properties for high potential applications in catalysis, optoelectronics, and gas sensors.

Herein, CoFe 2 O 4 nanoparticles were directly synthesized through a solution combustion method using ferric nitrate, cobalt nitrate, and glycine as raw materials. The effects of glycine on the phase composition and magnetic properties of the CoFe 2 O 4 products were investigated. When the fuel/ferric nitrate ratio was 0.8, the obtained product was pure CoFe 2 O 4 with an average particle size of 25 nm. Furthermore, the saturation magnetization is 77.3 emu/g, which is about 95.7% that of CoFe 2 O 4 bulk materials at room temperature and good for recycling. The photo-Fenton catalytic properties of CoFe 2 O 4 were investigated for assessing its efficacy in removing dyes. It could degrade the 20 ppm MB in 75 min. To improve the photo-Fenton catalytic performance, NH 4 HCO 3 and glucose were employed as additives. Due to the pores formed by NH 4 HCO 3 and glucose, the G-CoFe 2 O 4 and N-CoFe 2 O 4 could degrade the 20 ppm MB in 40 and 25 min, respectively. The results indicated that these additives can effectively improve the catalytic activity of CoFe 2 O 4 . The modified CoFe 2 O 4 is a promising alternative recyclable photo-Fenton catalyst for removing organic dyes.
