Summary: A simple method was developed to prepare ordered mesoporous carbons embedded with molybdenum. Three different ordered molybdenum carbide materials with mesoporous structures were prepared to investigate their influence on HER catalytic efficiency. The ordered mesoporous molybdenum carbide catalysts showed excellent HER electro-catalytic performance, with fCMK-3-MoCx exhibiting the best performance. This was attributed to its high specific surface area and highly ordered mesoporous structure, resulting in efficient proton transport and electron transfer.

Summary: In this study, Mn-doped copper (II) oxide (CuO) nanoflower spheres (CuO-1% Mn nanoflower spheres) were synthesized via a simple low-temperature hydrothermal method. The synthesized sample was characterized using various techniques, including XRD, SEM, TEM, EDS, XPS, Raman, and BET analysis. The results showed that the nanoflower spheres comprised of nanosheets with diameters ranging from 5-10 µm. Additionally, Mn ions were uniformly doped into the CuO nanoflower spheres, resulting in a surface area of 33.079 m(2)/g for CuO-1% Mn nanoflower spheres. At an optimized temperature of 235 degrees C and with 1% Mn doping, the CuO-1% Mn nanoflower spheres exhibited the highest sensitivity towards isopropanol, with a response almost 11.5 times higher than pure CuO. The doped sample also demonstrated excellent selectivity, repeatability, and durability. It is believed that the improved sensing properties are attributed to the doping of Mn ions, which introduced more defects and spillover effect, leading to the generation of more oxygen anions and oxidation of isopropanol molecules on the surface of CuO-1% Mn nanoflower spheres. This product shows great potential for the detection of isopropanol.

Summary: This review systematically summarizes recent progress on the catalytic oxidation of VOCs at ambient temperature. The structure-activity relationship in the catalytic oxidation process can be influenced by adjusting the structure of nanoparticle catalysts, cluster catalysts, and single-atom catalysts. The catalytic activity is also affected by process conditions. Currently, ambient temperature catalytic oxidation is mainly used for the removal of easily degradable pollutants, and there is a need to improve the activity, selectivity, and stability of catalysts. New prospects and challenges are proposed based on the existing problems and limitations in the application of ambient temperature catalytic oxidation technology.

Summary: This paper synthesized diatomite-like potassium iron disulfide (KFeS2) using a multistep sacrificial template method, and investigated its morphological, electrochemical, and oxygen evolution reaction (OER) properties. It was found that KFeS2 had a porous, hollow, and cake-like structure, with a high specific surface area (SSA) and abundant electrochemically active sites. The unique structure and high porosity of KFeS2 resulted in a very high specific capacitance of 651 F g(-1). Additionally, diatomite-like KFeS2 showed a very low overpotential and a small Tafel slope, indicating its broad application prospects for energy storage and conversion.

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: One-dimensional iron-nickel heterogeneous nanowires with superior electromagnetic wave absorption were prepared using a magnetic-field-assisted liquid-phase reduction method. The electromagnetic properties of the absorber were controlled by changing the atomic molar ratio of Fe to Ni, with the composition of Fe:Ni atomic molar ratio of 1:1.5 exhibiting the best absorption characteristics. The absorber showed a minimum reflection loss of 26.106 dB at 18 GHz with a matched thickness of 2.175 mm and an effective absorption bandwidth of 6.08 GHz at 2.6 mm with a filler content of 25%. The successful exploration of this one-dimensional heterogeneous structure provides important insights for the future fabrication of absorbers with excellent electromagnetic wave absorption capability.

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.
