For the purpose of sensing hydrogen gas, we synthesized a simple and reliable technique for doping Pd onto WO3 nanospheres. Porous WO3 nanostructure combined with the spillover effect of Pd allows for the detection of hydrogen at concentrations as low as 5 ppm at 100ºC while maintaining high selectivity over other gases. These impressive results can be traced back to uniform and robust Pd doping on the surface of WO3 nanospheres, making the material a desirable option for real-world applications.
