Aqueous synthesis of tin- and indium-doped WO₃ films via evaporation-driven deposition and their electrochromic properties

Abstract

WO3 and M-doped WO3 (M = Sn or In) electrochromic films were obtained from aqueous solutions via evaporation-driven deposition. The In–WO3 films showed a faster electrochromic response than WO3 and Sn–WO3 films, and a good cycle stability.

Review on recent progress in WO3-based electrochromic films: preparation methods and performance enhancement strategies

“…There are various kinds of methods to fabricate WO 3 EC films, such as magnetron sputtering, 56,66–72 sol–gel, 49,51,73–83 hydrothermal, 37,84–87 electrodeposition, 14,88–91 inkjet printing, 92 self-assembly, 42,93,94 chemical vapor deposition (CVD), 95,96 vacuum evaporation, 53,97–102 and so on. The structure and EC performance of the WO 3 films have obvious differences resulting from the various preparation methods and conditions.…”

Review and Development of Anode Electrocatalyst Carriers for Direct Methanol Fuel Cell

“…Among the noncarbon-based materials, metal compounds have been extensively studied, which are especially important to solve the problem of catalyst resistance to poisoning. [26,27] In addition, self-supporting carriers are of great interest due to their unique advantages. 1) Direct contact between catalytic materials and collectors reduces ion diffusion resistance and greatly enhances electronic properties.…”
