Activating oxygen deficient TiO in the visible region by BiMoO for CO photoreduction to methanol.

Fast photogenerated charge recombination and inappropriate bandgap for visible light driven charge generation hinders the performance of TiO. In this study, TiO was activated for visible light driven CO reduction in the presence of BiMoO as an electron donor. Furthermore, the introduction of oxygen vacancies resulted in enhanced CO adsorption and conversion.

Polyoxotungstate ([PWO]) immobilized on mesoporous polymer for selective liquid-phase oxidation of alcohols using HO.

Selective oxidation of alcohols is an attractive organic transformation and has received tremendous attention from the scientific community over the years. Herein, a mesoporous polymer (MP) was synthesized by a template-free solvothermal approach. The surface of the MP was functionalized with quaternary ammonium groups and polyoxotungstate anion (PWO ) was subsequently supported on the MP as a counter anion to the ammonium cation by a simple ion-exchange procedure.

Solid acid catalyzed carboxymethylation of bio-derived alcohols: an efficient process for the synthesis of alkyl methyl carbonates.

Acid catalyzed carboxymethylation of alcohols is an emerging organic transformation that has grabbed the attention of scientific community in recent years. In the present study, sulfonated mesoporous polymer (MP-SOH) is presented as a highly active solid acid catalyst to convert a wide range of alcohols into alkyl methyl carbonates. The remarkable catalytic activity of MP-SOH is comparable to that of reported homogeneous acid catalysts.

Exploring the Brønsted acidity of UiO-66 (Zr, Ce, Hf) metal-organic frameworks for efficient solketal synthesis from glycerol acetalization.

Zr, Ce, Hf-based isostructural UIO-66 MOFs exhibited varying degree of Brønsted acidity (UiO-66(Hf) > UiO-66(Ce) > UiO-66(Zr)) on their secondary building units owing to the differences in their oxophilicities. UIO-66(Hf) showed remarkable catalytic activity for solketal synthesis with a turnover frequency as high as 13 886 h-1, which is 90 times higher than that of UiO-66(Zr) and several orders of magnitude higher than that of H2SO4 or Zeolites.
