Summary: In this study, a fraction of structural Mn cations in cryptomelane oxide K-OMS2 were replaced by different cationic dopants, resulting in the weakening of the Mn-O bond and the production of oxygen vacancy defects. The most active catalyst was found to be the ruthenium doped cryptomelane oxide, which exhibited a higher reducibility and a more weakened Mn-O bond force constant value. All the doping processes enhanced the alcohol conversion and showed a high selectivity towards the aldehyde.

Summary: Manganese oxides with different structures were synthesized and impregnated with sodium tungstate to enhance their catalytic performance in the selective epoxidation of cyclopentene. OL-1 exhibited the highest conversion and selectivity, while the structure and activity of OMS-1 were affected by tungstate impregnation. The presence of Mn2+ was found to be essential for the epoxidation reaction, and the reaction between tungstate ions and Mg2+ and/or Mn2+ during impregnation resulted in the formation of an inactive amorphous compound. Tungstate impregnation had no effect on the crystalline and chemical structure of OMS-2, which exhibited radical activity for the total oxidation of organic compounds in the presence of hydrogen peroxide.

Summary: The mechanism of simultaneous activation of O-2 and surface lattice O2- on one active metallic site is still unclear. In this study, we designed Cu-1/TiO2 single atom catalysts (SACs) with abundant oxygen activation sites. Charge transfer between Cu and TiO2 generates Cu-I and 2-coordinated O-lat sites, facilitating the chemisorption and activation of O-2 molecules. The Cu-1-O-Ti active site also induces TiO2 lattice distortion, activating adjacent surface lattice O2-, achieving the dual activation of O-2 and surface lattice O2-. Modulating the electron properties of SACs can boost heterogeneous catalytic oxidation activity.

Summary: In this study, TiO2-supported copper catalysts (CuOx/TiO2) with different ratio of oxygen vacancies (Ov) and Cu+ were synthesized, and the existence and amount of Ov and Cu+ species were characterized. The synergetic effect between Cu+ and oxygen vacancies was investigated, and Cu+ was found to be the adsorption site for CO molecules, while abundant Ov could effectively activate molecular oxygen to oxidize CO. The most suitable ratio between Cu+ and Ov was confirmed, and CuOx/TiO2 (Cu+ rich) catalyst exhibited superior CO oxidation activity compared to CuOx/TiO2 (Ov rich) catalyst.

Summary: A series of mixed-phase Zr-doped TiO2 photocatalysts were synthesized using a sol-gel technique and their performance in the photocatalytic degradation of orange II dye was investigated. Characterization methods including XRD, TEM, XRF, Raman spectroscopy, TGA, and XPS revealed the composition and structure of the materials. The results showed that the photocatalysts consisted of zirconium, titanium, and oxygen, with anatase and rutile phases of TiO2 present. The undoped TiO2 exhibited the highest stability, and the materials successfully degraded orange II dye solution up to 7 cycles through asymmetric cleavage of the azo bond.

Summary: We used polymer N-heterocyclic carbenes (NHCs) to control the microenvironment surrounding metal nanocatalysts, enhancing their catalytic performance in CO2 electroreduction. Three polymer NHC ligands were designed with different hydrophobicity: hydrophilic poly(ethylene oxide) (PEO-NHC), hydrophobic polystyrene (PS-NHC), and amphiphilic block copolymer (PEO-b-PS-NHC). The introduction of hydrophobic PS segments led to a twofold increase in the partial current density for CO formation. The hydrophobic polymers altered the hydrogen bonding structures of water, improving CO2 diffusion and subsequent reduction.
