Isopropoxy Tetramethyl Dioxaborolane on TiO₂: Reaction Pathway and Formation of a Visible-Light-Sensitive Photocatalyst.

ABSTRACT: Borate toxicity is a concern in agriculture since a high level of borates may likely exist in irrigation water systems. In this research, transmission infrared spectroscopy and X-ray photoelectron spectroscopy are employed to study the thermal and photochemical reactions of isopropoxy tetramethyl dioxaborolane (ITDB) on TiO₂, with the aid of density functional theory calculations. In addition, the possibility for the formation of a boron-modified TiO₂ (B/TiO₂) surface, using ITDB as the boron source, is explored and the photocatalytic activity of the B/TiO₂ is tested. After adsorption of ITDB on TiO₂ at 35 °C and heating the surface to a temperature higher than ∼200 °C in a vacuum, the surface is found to be covered with both the organ
