|Abstract:||A high-yield synthesis of SnO2 nanoparticles via a facile, economical and easily scalable solid-state molten salt synthesis method has been demonstrated. The inorganic additive, molar ratios of chemicals and annealing temperature were found to control the size and porosity of the SnO2 nanoparticles. The synthesized SnO2 nanostructures were uniform, well dispersed and exhibited high crystallinity. Hydrogen sensors made from the SnO2 nanoparticles were found to possess high sensitivity and stability. Other than tailoring the material's structure in terms of size and porosity, another potential method of enhancing the gas sensitivity is functionalization with noble Pd metal. © IOP Publishing Ltd.|
