“…Several methods have applied in the preparation of Pt nanoparticle deposited on TiO 2 substrates included underpotential deposition [127–129], hydrothermal treatment [130, 131], photoassisted reduction [132], and vacuum deposition [133, 134]. Electrodeposition would be a straightforward approach for the synthesis of Pt-supported TiO 2 , which is highly required for the production of complex electrode architectures in fuel cells [132–134].…”

The lack of stability is a challenge for most heterogeneous catalysts. During operations, the agglomeration of particles may block the active sites of the catalyst, which is believed to contribute to its instability. Recently, titanium oxide (TiO 2 ) was introduced as an alternative support material for heterogeneous catalyst due to the effect of its high surface area stabilizing the catalysts in its mesoporous structure. TiO 2 supported metal catalysts have attracted interest due to TiO 2 nanoparticles high activity for various reduction and oxidation reactions at low pressures and temperatures. Furthermore, TiO 2 was found to be a good metal oxide catalyst support due to the strong metal support interaction, chemical stability, and acid-base property. The aforementioned properties make heterogeneous TiO 2 supported catalysts show a high potential in photocatalyst-related applications, electrodes for wet solar cells, synthesis of fine chemicals, and others. This review focuses on TiO 2 as a support material for heterogeneous catalysts and its potential applications.

“…To date, TiO 2 nanotubes have been produced through a variety of methods such as hydrothermal treatment [8,9], template-assistant deposition [10], the anodic oxidation is shown to be a powerful method. Gong et al [11] has fabricated the first generation TiO 2 nanotubes by anodization using an aqueous HF-based electrolyte.…”
