A facile synthesis of Pd-doped SnO2 hollow microcubes with enhanced sensing performance

A novel and convenient synthesis of Pd-doped SnO2 hollow microcubes (PdO–SnO2 HCs) have been achieved via successively annealing and acid etching cube-like hollow zinc hydroxystannate (ZnSn(OH)6) decorated with Pd(OH)2. The resulting PdO–SnO2 HCs possess special cube-like hollow interiors with void architectures together with a porous surface composed of nano-sized primary SnO2 nanoparticles. Utilized as the composite materials in sensors, the...
