A Facile Synthesis of PdO‐Decorated SnO 2 Nanocomposites with Open Porous Hierarchical Architectures for Gas Sensors

PdO‐decorated SnO 2 nanocomposites with open porous hierarchical architectures are fabricated through a facile biotemplating sol–gel technique. The sol–gel soakage process is carried out by immersing the templates butterfly wings in Sn‐ and Pd‐ impregnants successively to generate a uniform colloid...

Summary:PdO‐decorated SnO 2 nanocomposites with open porous hierarchical architectures are fabricated through a facile biotemplating sol–gel technique. The sol–gel soakage process is carried out by immersing the templates butterfly wings in Sn‐ and Pd‐ impregnants successively to generate a uniform colloid layer. PdO and SnO 2 nanocrystallites come into being with subsequent calcination treatment, and PdO‐decorated SnO 2 nanocomposites further construct the parallel main ridges with connective pillars and vertical struts, finally present a 3‐D open porous hierarchical architecture. Benefiting from unique ingredients and structure hierarchy, the nanocomposites give enhanced acetone‐sensing performance of high sensitivity and rapid response/recovery rate
