Summary: In this paper, In2O3/g-C3N4/rGO nanocomposites as a novel high-performance NOx gas sensor are successfully prepared by the solvothermal method. The gas sensing performance of In2O3/g-C3N4/rGO towards NOx is significantly enhanced, with a response (2040) to 100 ppm NOx about seven times more than In2O3/g-C3N4. Meanwhile, In2O3/g-C3N4/rGO has a faster reaction/recovery time (96/52 s) than In2O3/g-C3N4 and exhibits good selectivity, reproducibility, and low detection limits. The adsorption process of NOx on the surface of In2O3/g-C3N4/rGO is studied by Diffuse Reflectance Infrared Fourier Transformed (DRIFT). The gas-sensitive properties of In2O3/g-C3N4/rGO are enhanced due to the heterogeneous structure formed among the MOF-derived In2O3 nanotubes, g-C3N4, and rGO nanosheets and their large specific surface area. The good electron mobility of rGO, the sensitizing effect of g-C3N4, and the unique structure of MOF-derived In2O3 are also advantageous for enhancing gas sensing performance. Therefore, In2O3/g-C3N4/rGO ternary nanocomposites are excellent candidates for NOx gas sensors.

Summary: Nitrogen oxides (NOx) pollutants have adverse environmental effects and can lead to acid rain, ozone pollution, smog, and global warming. Photocatalysis using graphitic carbon nitride (g-C3N4) is a promising technology for tackling NOx pollution. However, the pristine form of g-C3N4 has limitations in terms of light response, charge carrier recombination, specific surface area, and active sites, resulting in low solar light efficiency and unsatisfactory photocatalytic performance. In this review, recent advances in modifying g-C3N4-based photocatalysts for NOx removal are summarized and discussed, along with the challenges and future research topics in this field.

Summary: B and N mixed anions co-doped titania with various crystal phases were successfully synthesized by hydrothermal synthesis and heat treatment in an ammonia gas atmosphere. The different phases exhibited different color and photocatalytic deNO(x) activity. Among them, BN-Bro showed excellent photocatalytic deNO(x) activity, surpassing the standard titania photocatalyst Degussa P25. The colorful titania with low-photocatalytic activity has the potential to be used as nontoxic color pigments or novel cosmetic raw materials.

Summary: A hybrid material consisting of anisotropic niobate layers modified with MoC nanoparticles was synthesized through multistep reactions. Stepwise interlayer reactions induced selective surface modification at alternate interlayers, leading to the formation of double-layered nanosheets after ultrasonication. Liquid phase MoC deposition with the double-layered nanosheets resulted in the decoration of MoC nanoparticles on their surfaces. The hybrid can be considered as a stacking of two layers with anisotropically modified nanoparticles. The hybridization method showed potential for the synthesis of semiconductor nanosheets and co-catalyst nanoparticles for photocatalytic applications, as evidenced by the photocatalytic activity exhibited by the heated hybrid material.

Summary: The functionality of inorganic materials depends on their chemical composition, morphology, particle size, and crystal facet, which are influenced by the synthesis process. Precise control of the synthesis process can lead to the discovery of new functionality and improvement of materials. Solution processes allow for precise control of morphology and particle size, and are strongly related to the dissolution reprecipitation mechanism, enabling strict control of material composition and formation of highly crystalline particles. This review focuses on the role of solvents in the solution process, their effect on particle size and morphology of transition metal oxides, related functional improvements, direct formation of functional thin films, and morphology control by non-oxide materials through topotactic reactions.

Summary: The recombination of photocarriers is a crucial factor affecting the performance of photocatalysts. The design of heterojunction photocatalysts can effectively inhibit the recombination by enhancing photocarrier separation and transport. In this study, a Z-scheme WS2/In2S3 photocatalyst with a bi-layered sheet-like structure was synthesized. The unique architecture of this photocatalyst reduced the charge transfer distance and provided more surface area, promoting the photocatalytic reaction. The Z-scheme structure effectively separated and retained the strong redox capability of the photocarriers, resulting in remarkable photocatalytic activity for H-2 generation and tetracycline hydrochloride degradation. The Z-scheme WS2/In2S3 composite showed the highest H-2 generation rate of 592.9 mu mol g(-1) h(-1) and the best degradation efficiency of 90% within 60 min. The bi-layered Z-scheme photocatalyst also demonstrated excellent stability and recyclability.

Summary: This study investigates the photocatalytic activity of small particles of BiVO4 for O-2 evolution, using Fe3+ as the electron acceptor. The results show that annealing treatment at 400°C can significantly improve the activity of milled BiVO4, while ball milling treatment accelerates recombination but increases the specific surface area. The annealed small BiVO4 particles exhibit high activity in both sacrificial O-2 evolution and overall water splitting by Z-scheme systems.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
