Summary: CeO2-supported Pt catalysts with different pore structures were synthesized using different mesoporous silica templates. The effects of pore structure on the surface and adsorption properties of the catalysts were investigated. The results showed that the catalyst synthesized from SBA-15 template had the largest number of active metal sites due to its larger pore volume and pore size.

Summary: Electrochemical sensors are increasingly important in medicine, environmental monitoring, and industrial process control. However, their development faces challenges such as low target compound concentrations and complex analytical matrices. Mesoporous Thin Films (MTFs) have attracted great interest as electrode modifications due to their high surface area, uniform pore distribution, and electrochemical signal modulation possibilities. To fully exploit the advantages of MTFs, reproducible methods for sensitive and selective MTF-modified electrodes need to be developed, and mass and charge transport processes within the film and on the electrode need to be understood.

Summary: Incorporation of magnesium nitrate into the precursors during the synthesis of ordered mesoporous carbons improved pore uniformity and volume. The addition of magnesium nitrate lowered the melting point of resorcinol, increased diffusivity, and promoted self-assembly. It resulted in a modification of the pore structure and prevented shrinkage under high-temperature conditions, enhancing uniformity and mesopore volume. This novel method also significantly increased the capacity of electric double-layer capacitors.

Summary: The study investigates the chloroaluminate ion storage properties of various carbonaceous electrodes, with AC and CMK-8 exhibiting the highest reversible capacities. The unique CMK-8 framework provides interpenetrating three-dimensional open channels for electrolyte accessibility and contributes to the electrode's great rate capability and excellent cyclability. The charge storage mechanism of the CMK-8 electrode involves both capacitive contribution and diffusion-controlled intercalation/deintercalation processes.

Summary: By using an organocatalytic polymerization method, well-defined amphiphilic block copolyethers can be prepared and applied as structure-directing agents in a standard soft templating process to deliver ordered mesoporous carbons with monomodal and narrowly distributed pore diameters. Selective tuning of pore diameters in the range of 6-18 nm is achievable by judiciously choosing the properties of the structure-directing agents, potentially reducing the effort required to obtain systematically altered materials.

Summary: Due to their unique properties, such as high surface area, enhanced catalytic properties, and biological applications, there is growing interest in porous materials. While solvent-based approaches have been used to synthesize porous materials, the large volume of solvents, their toxicity, and time-consuming synthesis make this process less effective in terms of green chemistry principles. Mechanochemical synthesis provides an effective and eco-friendly alternative, using ball milling to efficiently mix reactants with minimal or no solvents, resulting in smaller nanoparticles and larger surface area, which is highly beneficial for antimicrobial applications.

Summary: Photodynamic therapy (PDT) is a promising alternative to traditional active substance release methods, utilizing photosensitizers and specific energy radiation. Curcumin, a natural photosensitizer, has anti-inflammatory, antioxidant, and anti-cancer effects. However, the solubility of curcumin in water limits its clinical application in PDT. Using hierarchical zeolites as carriers is a potential strategy to overcome this difficulty.

Summary: We investigated the synthesis of ordered mesoporous carbons with tunable mesopores and well-developed irregular microporosity using ecofriendly chemicals as carbon precursors and a triblock copolymer as a soft templating agent. Different block copolymers were used to tailor the structural properties of the resulting carbons. The weight ratios of tannin and block copolymer were employed to adjust the textural properties of the carbons. The obtained CO2-activated carbon samples showed high specific surface area, large pore volume, narrow pore size distribution, and high CO2 uptake.
