Special Issue Information

Dear Colleagues,

Porous materials are a variety of materials that have a porous structure, large surface area, and rich porosity. They have attracted the interest of numerous researchers and have been widely used in many fields, such as catalysis, adsorption, energy storage, analysis, and drug delivery, due to their unique pore characteristics. With the development of material preparation techniques, more and more porous materials have been developed, including molecular sieves, porous carbons, metal–organic frameworks, covalent organic frameworks, porous metal oxide, and porous composites, for instance. This Special Issue of Molecules, titled “Recent Advances in Porous Materials, 2nd Edition”, is focused on recent progress and research from the past few years on the production, characterization, and application of various porous materials. We welcome research works, review documents, and communications that cover new concepts, current challenges, and strategies on the synthesis of various porous materials and their applications in crosscutting areas.

We encourage you to contribute to this research effort by submitting your work to this Special Issue of Molecules.

Chronic wound healing remains a major challenge in diabetes management due to prolonged inflammation, autonomic neuropathy, and bacterial infections. In particular, multidrug-resistant bacterial infections are important to the development of diabetic wounds, leading to persistent inflammation and delayed healing. To address this issue, we developed a self-adaptive nanozyme designed to modulate infectious and inflammatory microenvironments by doping Ce and Ag into mesoporous silicon nanomaterials (MSNs). The resulting CA@MSNs exhibited strong bacterial capture capabilities via electrostatic attraction. Additionally, the synergistic effects of Ce and Ag endowed CA@MSNs with peroxidase (POD)-like activity, enabling the generation of reactive oxygen species (ROS) to eradicate bacteria in infectious microenvironments. Notably, CA@MSNs also demonstrated the ability to scavenge a broad spectrum of ROS, including hydroxyl free radicals, hydrogen peroxide, and superoxide radicals, in inflammatory microenvironments. This dual functionality helped mitigate inflammation and promote endothelial cell migration. Consequently, treatment with CA@MSNs significantly reduced inflammation, enhanced fibroblast activation, and facilitated collagen deposition, ultimately accelerating the healing of methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds in diabetic mice. In conclusion, this study presents a promising therapeutic strategy for chronic diabetic wounds, offering a novel approach to overcoming infection-related healing delays. Full article

The production of formic acid (FA) from lignocellulose and its derived sugars represents a pivotal upgrading reaction in biorefinery. This work prepared a Mn-Mo doped carbon nanotube composite catalyst for the catalytic oxidation of glucose into FA in an O2 atmosphere, under extremely low Mn (3.27%) and Mo (0.40%) loading conditions, displaying a comparable performance with the traditional vanadium-based catalyst suffering from toxicity issues. It was confirmed that the doping of Mo led to the formation of MnMoOX and increased the contents of low-valence Mn species (Mn2+ + Mn3+), lattice oxygen (Olatt), and surface adsorbed oxygen (Oads) based on various characterization methods, such as XRD, XPS, TEM and ICP, which were beneficial to improve the catalytic performance. The maximum FA yield of 58.8% could be achieved over Mn9Mo1OX@MWCNT after reaction for 6 h at 140 °C, which was far more than that obtained with undoped MnOX@MWCNT (14.5%) at the identical conditions. Glyoxylic acid and arabinose were identified as two main intermediates, suggesting that the transformation of glucose into FA over Mn9Mo1OX@MWCNT involved two different paths. This work proved that manganese-based catalyst was a green alternative for upgrading lignocellulose via catalytic oxidation. Full article

The catalytic production of lactic acid from carbohydrates was considered a green way to efficiently utilize renewable biomass resources. In this study, an easy post-synthesis method was used to prepare a Sn-Beta catalyst for the production of lactic acid from glucose at 180 °C, 2 MPa, and 30 min. With optimized reaction time, temperature, pressure, and the ratio of raw material to catalyst, the yield of lactic acid reached an astonishingly high level of 76.0%. In addition, the catalyst characterizations were performed in-depth, revealing the intrinsic relationship between catalyst performance and structure, proving that the 2 wt% Sn was uniformly dispersed in the skeleton of Beta zeolite, which significantly increased the density of Lewis acid. Thus, the enhanced isomerization and retro-aldol condensation processes over the Lewis acid sites led to the high yield of lactic acid. This catalytic system kept stable after five cycles at mild conditions, showing high potential for industrial biomass utilization. Full article
