Preparation of TiO₂ Nanorods@Ni-Foam for Photocatalytic Decomposition of Acetaldehyde-In Situ FTIR Surface Investigation.

ABSTRACT: TNR@Ni-foam structures were prepared by an alkaline hydrothermal method in an autoclave in a strongly alkaline medium (10 M NaOH) at 150 °C with further acid washing (0.1 M HNO₃) and a second hydrothermal treatment in an autoclave at 180 °C. Two TiO₂ samples were used for preparation: anatase and P25 of mixed anatase and rutile phases. After the first step of hydrothermal treatment, a layered titanate structure was obtained (Na₂Ti₃O₇). Acid washing caused the substitution of Na⁺ by H⁺ and launched the formation of TNR. After the second hydrothermal treatment at 180 °C, for the optimal quantity of acid used for washing (10 mL per 0.75 g of TiO₂), titania was crystallized to an anatase phase with small qu
