Photocatalytic partial oxidation of methanol to methyl formate under visible light irradiation on Bi-doped TiO₂viatuning band structure and surface hydroxyls

Abstract

Bi-doped titania is well studied for photocatalytic partial oxidation of methanol to methyl formate under visible light irradiation.

An efficient catalyst of CuPt/TiO2 for photocatalytic direct dehydrogenation of methanol to methyl formate at ambient temperature

“…As in our previous work, [16][17][18]45 the photocatalytic activity of the catalyst was performed in a continuous flow aluminum alloy reactor (Fig. 13).…”

Bi Doped TiO2 as a Photocatalyst for Enhanced Photocatalytic Activity

“…has been extensively studied. However, it is rarely used in photocatalytic oxidation reactions due to its more complex reaction mechanism [22]. According to Ma et al [22], Bi doped TiO2 catalyst displays visible light driven photoactive properties for oxidation of methanol to methyl formate, increasing the surface hydroxyls and decreased the band gap energy.…”

“…However, it is rarely used in photocatalytic oxidation reactions due to its more complex reaction mechanism [22]. According to Ma et al [22], Bi doped TiO2 catalyst displays visible light driven photoactive properties for oxidation of methanol to methyl formate, increasing the surface hydroxyls and decreased the band gap energy. Li et al [23] showed that by doping Bi into TiO2, TiO2 created a new intermediate energy level below its conduction band edge, thus prolonging the absorption in the visible region and increased their photocatalytic efficiency.…”
