Summary: The synthesis of various periodic mesoporous organosilica nanoparticles (nanoPMOs) from organo-bridged bis(triethoxy)silanes is described. The influence of sodium hydroxide concentration on the size and morphology of the nanoparticles is observed. Comparison of the resulting hybrid nanoPMOs reveals significant differences in their adsorption properties towards rhodamine B (RB) and highlights the strong affinity of phenylene PMO with the dye. Additionally, it is found that the phenylene-bridged nanoPMO exhibits higher lipophilicity compared to other studied linkers.

Summary: This study proposes a promising synthetic method for functionalized titanium dioxide (TiO2) by combining photoactive porphyrin-periodic mesoporous organosilica (PMO) with hollow TiO2 nanospheres, forming a multi-component synergistic system. The prepared composite TiO2@Pro exhibits photocatalytic activity in the aerobic oxidation of sulfide in the aqueous phase under visible light. The high reactivity is attributed to the catalyst's large specific surface area, amphiphilicity, wide visible light absorption, and high electron-hole pair separation rate. This strategy provides a new approach for designing TiO2-based photocatalysts for heterogeneous catalysis under visible light.

Summary: The study using density functional theory revealed that periodic mesoporous organosilicas have potential for selective CO2 adsorption due to stronger interactions with CO2 compared to CH4. Materials with phenylene moieties showed more favorable contacts with CO2, and the presence of bipyridine-bridges improved CO2 adsorption behavior when mixed with biphenylene moieties. The adsorption strength of CO2 gas was found to increase with a decrease in the SiOH ●●● OCO distance.

Summary: This study investigated the effect of KCl and (NH4)2SO4 salts on the solubility of L-aspartic acid, L-glutamic acid, L-tryptophan, and L-tyrosine. The results showed that both salts had a salting-in effect on glutamic acid and aspartic acid, with (NH4)2SO4 having a stronger effect. For the aromatic amino acids, there was a slight increase in solubility at low salt concentrations, followed by a stronger salting-out effect, particularly with (NH4)2SO4. Furthermore, the relative solubility data were compared and a ranking connected to the amino acids' structure was established.

Summary: MXenes are proposed as efficient catalysts for N2 dissociation. By depositing one atom of a transition metal element on the Ti2C MXene surface, the catalytic potential of the MXene can be further improved as a single-atom catalyst. This reduces the energy required for breaking the triple bond in N2 and may impact the nitrogen-to-ammonia process.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
