Summary: The optoelectronic properties of carbon and oxygen co-doped g-C3N4 (COCN) were investigated using density functional theory. The results show that COCN has a smaller direct bandgap and stronger visible light absorption compared to Pure and Single-doped g-C3N4. The COCN forms a built-in electric field that facilitates the separation of electron-hole pairs, and its band edge positions match the redox potential of efficient photocatalytic oxidation. The synergetic effect of C/O co-doping promotes the adsorption of toluene on the COCN surface.

Summary: In this study, density functional theory calculations were used to investigate the reactivity of Pd- and Zr-doped CeO2(111) surfaces at different locations. The results show that both Pd and Zr doping can activate the surface lattice O and lower the energy barriers of CO oxidation. However, the promotion effect of Zr doping is limited to the first surface layer, while Pd doping can greatly enhance surface activity even below the surface. CO2 can be directly generated on Pd-doped surfaces through the reaction between CO and surface O, while on Zr-doped surfaces, the formation of surface intermediate CO2d- may restrict the release of CO2 by further oxidation to carbonates. Electronic analysis reveals that the doped Pd exists as Pd4+ and has stronger electron affinity, facilitating the transformation from Pd4+ to Pd2+ and the direct formation of CO2 during CO oxidation.

Summary: To overcome the high electron-hole pair recombination rate of g-C3N4 as a photocatalyst, an efficient photocatalyst of g-C3N4/Bi2MoO6/kaolinite composite was constructed in this study. The g-C3N4 prepared by thermal condensation and Bi2MoO6/kaolinite prepared by hydrothermal method were tightly combined using electrostatic self-assembly. The multilevel structure of the composite confirmed the successful collaboration of the three components. The composite exhibited excellent photocatalytic performance when the mass ratio of Bi2MoO6/kaolinite and g-C3N4 was 0.25:0.75. The close contact and layered assembly of kaolinite and Bi2MoO6/g-C3N4 heterostructure contributed to the synergistic effect and the exceptional photocatalytic performance.

Summary: A series of Fe-doped alumino-borate catalysts (18% Fe-PKU-1) with different crystalline qualities were obtained by varying synthesis conditions. The crystalline quality was found to be correlated with the surface composition and electronic structure of Fe-PKU-1, especially for the boron species, as shown by Angle-resolved X-ray Photoelectron Spectroscopy, pyridine adsorption infrared spectroscopy, and potentiometric titration. By systematically changing the synthesis conditions, the catalyst with the appropriate crystalline quality exhibited the highest surface compositions of boron and oxygen vacancies, resulting in strong surface Lewis acidity and excellent catalytic performance in glycerin ketalization, with 97% conversion and 99% selectivity in DL-1,2Isopropylideneglycerol (Solketal).

Summary: The superior selectivity of catalytic NO oxidation to bidentate nitrate with simultaneous NO2 inhibition is achieved by the oriented formation of singlet oxygen (O-1(2)). This work demonstrates the successful conversion of NO into NO3(-) instead of NO2 through tailored exposure of Lewis acid sites on the surface of ZrO2, enabling precise control over the ROS evolution process for selective NO oxidation. The presence of Lewis acid sites as electron acceptors induces electron redistribution, charge-carrier transfer, and further oxidation of •O-2(-), promoting the oriented formation of O-1(2) and resulting in excellent NO conversion efficiency and low NO2 selectivity.

Summary: In this study, core-shell heterostructured nanocomposites (Fe NWs@SiO2) were successfully prepared, consisting of ferromagnetic nanowires (Fe NWs) as the core and silica (SiO2) as the shell. These composites exhibited enhanced electromagnetic wave absorption and oxidation resistance and were synthesized using a simple liquid-phase hydrolysis reaction. The microwave absorption properties of Fe NWs@SiO2 composites with different filling rates were tested and analyzed, with the sample filled with 50 wt% showing the best comprehensive performance. At a matching thickness of 7.25 mm, the minimum reflection loss (RLmin) could reach -54.88 dB at 13.52 GHz and the effective absorption bandwidth (EAB, RL < -10 dB) could reach 2.88 GHz in the range of 8.96-17.12 GHz. The enhanced microwave absorption performance of the core-shell structured Fe NWs@SiO2 composites could be attributed to the magnetic loss of the composite, the core-shell heterogeneous interface polarization effect, and the small-scale effect induced by the one-dimensional structure. Theoretically, this research provided Fe NWs@SiO2 composites with highly absorbent and antioxidant core-shell structures for future practical applications.

Summary: This study prepared a series of MOF-based derivatives using suitable methods and evaluated their electrochemical performance. It was found that phosphating treatment can enhance the material's electrical conductivity, while the layered structure facilitates the intercalation/deintercalation of electrolyte ions, and oxidation inhibits the release of electrochemical performance. Therefore, the enhancement effect in terms of electrochemical performance is ranked as follows: phosphorization > layer structure > oxidation. This study provides reliable criteria for the design and screening of advanced electrode materials.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
