Abstract

In(OH) ₃ and InOOH were synthesized in a high-temperature continuous flow microreactor, which was much faster than the hydrothermal synthesis in a Teflon-lined autoclave. The phase transition interval of In(OH) ₃ and InOOH is measured, and the effect of aging temperatures on equilibrium compositions was also theoretically calculated. A transformation from nanorods to nanocubes was observed when the aging temperatures increased. In(OH) ₃ and InOOH were also synthesized with Sn dopant, which was proven to be beneficial for the transformation from In(OH) ₃ to InOOH. The sensors based on cubic and hexagonal In ₂ O ₃ particles showed a fast response (4-5 s) and recovery speed (12-15 s) to acetone vapor at the optimum operating temperature of 290 °C. The sensor based on hexagonal In ₂ O ₃ showed a higher response than that based on cubic In ₂ O ₃ . This work provided a rapid, continuous, and high-temperature synthesis method of an In(OH) ₃ , InOOH, and In ₂ O ₃ series.
