tivity towards methane, butane, and H2S [10, 11]. At the
same time, these nanoparticles are being actively researched
for their diluted magnetic semiconductor (DMS) properties
[12–14]. Current efforts are focused on the research of
effective production methods for such nanomaterials—
production methods that are facile and robust for scaleup.
Various chemical and physical synthesis methods have
been employed to generate composite or iron-doped SnO2
materials, including coprecipitation [10, 14], mechanical
