Simple preparation of nitrogen-doped TiO2 and its performance in selective oxidation of benzyl alcohol and benzylamine under visible light

Selective Oxidation of Benzyl Alcohol in the Aqueous Phase by TiO2‐Based Photocatalysts: A Review

“…Zhao et al [24] indicated that both . OH radicals and the photogenerated holes are mainly involved in the oxidation of benzyl alcohol into benzaldehyde with TiO 2 , while O À 2 works as the source of OH generation, similar to other reports [25,26]. Meanwhile, Bao et al [27] demonstrated that .…”

“…The VB upshift of the N-doped TiO 2 was observed and responsible for the low energy bandgap of 2.3 eV. Thus, the VLR was significantly enhanced [26]. In addition, carbonate-like species-doped TiO 2 (C/T) was employed in the oxidation of BnOH with dimethyl carbonate as a solvent under visible light.…”

Hierarchical CeO2@N–C Ultrathin Nanosheets for Efficient Selective Oxidation of Benzylic Alcohols in Water

“…Impressively, CeO 2 @N–C USHR nanoparticles could also exhibit good stability with no obvious decrease in activity during 5 catalytic cycles (Figure e), and their original morphology and crystal structure had been well maintained (Figure S13). − To demonstrate the universality of this catalytic system, the oxidation of a variety of alcohol substrates was investigated over the CeO 2 @N–C USHR catalysts (Figure f, Table S2, and Figure S14). The oxidation of 4-hydroxybenzyl alcohol, 4-methylbenzyl alcohol, 4-methoxybenzyl alcohol, 2-aminobenzyl alcohol, cinnamyl alcohol, and indole-3-carbinol proceeds efficiently over the target catalyst CeO 2 @N–C USHR with high yields of their corresponding products; however, the attachment of electron-withdrawing groups (like −F, −Cl, and −Br) to the para-position of the phenyl ring largely decreased the efficiency of the oxidation reaction.…”

Facile synthesis of a nano titanium catalyst and its performance in selective oxidation of aromatic and pyridinic alcohols under visible light

“…For further comparison, this paper summarizes recent studies on photocatalytic benzyl alcohol oxidation over TiO 2 type catalysts under visible light irradiation, and these results are summarized in Table 2, which suggests that the prepared 150-TiO 2 exhibits excellent performance for the photocatalytic oxidation of benzyl alcohol into benzaldehyde, with high selectivity and conversion ratio under moderate reaction conditions. For example, noble metal loaded (AuNS@TiO 2 , n-TiO 2 -P25/Ag) 40,45 catalysis is not as efficient as 150-TiO 2 , but the catalyst fabrication cost is much higher than that of 150-TiO 2 , and non-metal element N-doped catalysts (T-400, TiO 2 @COF-3) 42,44 can achieve the results of this work only by increasing the amount of the catalyst or increasing the reaction time.…”
