Single-step or two-step aerosol assisted chemical vapor deposition methods have been used to grow single crystalline tungsten oxide nanowires loaded with different concentrations of nickel oxide nanoparticles. Working temperatures and nickel loadings were studied and optimized to achieve the optimal working conditions for detecting hydrogen sulfide. Morphology, crystalline structure, composition, sensing properties and mechanisms will be presented and discussed in detail. The twostep method allows for controlling Ni loading in a wide range while keeping constant particle size.
