TiO2 beads as photocatalyst and photoelectrode for dye‐sensitized solar cells synthesized by a microwave‐assisted hydrothermal method

摘要: Summary In this study, a two-step process involving sol–gel and microwave-assisted hydrothermal (MH) techniques has been used to synthesize novel TiO2 structure, namely, mesoporous beads. Various synthesis parameters were investigated study their effects on the resulting It was found that within processing conditions used, beads have similar sizes (~325 nm) contain uniform-sized anatase nanoparticles (<10 nm), which are single crystals. Crystalline obtained in as short 15 min at low temperature of only 140 °C without any post-process calcination. Less surface oxygen vacancies higher MH temperature. Compare commercial P-25 powders conventional synthesized beads, exhibit much values specific areas, pore volumes, porosities. The use photocatalyst photoelectrode for dye-sensitized solar cells also investigated. Copyright © 2015 John Wiley & Sons, Ltd.
