Summary: The new wedge model, based on TEM micrographs and experimental data, reveals the gas adsorption process on graphitized thermal carbon black. The overlapping interactions in wedge-shaped spaces and at the crystallite junctions enhance the interaction energy of the adsorbate molecules, facilitating molecular clustering and condensate formation. The experimental results show a better match with the simulation results based on the wedge model compared to the homogeneous planar graphite model.

Summary: In this study, a GO-like material PGCO was fabricated from oxidizing porous graphitized carbon (PGC), which showed a high oxidation degree and insolubility in water, offering a higher adsorption efficiency for heavy metals and successful regeneration by acid treatment. These results suggest that PGCO could be a promising alternative adsorbent for remediating toxic metal-contaminated waters.

Summary: Porous graphitized carbon fibers (PGCFs) with enhanced hydrophobicity were prepared by catalytic graphitization of ACFs. They showed high adsorption capacity for toluene, cyclohexane, and ethanol, and even increased adsorption of ethanol under humid conditions. The 7C electrons and high polarizability of PGCFs strengthened their interaction with non-polar organics, and capillary condensed water in mesopores acted as absorbate for polar ethanol.

Summary: In this study, hydrophobic bamboo-derived porous graphitized carbons (BPGCs) were prepared and showed high adsorption capacities for toluene, cyclo-hexane, and ethanol under dry conditions. Their adsorption capacities remained high for toluene and cyclohexane even at 80% relative humidity, and the uptake of ethanol increased. BPGC also exhibited faster adsorption kinetics compared to activated carbon.

Summary: This study demonstrates the preparation of hollow graphitized carbon spheres loaded with MnO2 nanosheets using a simple hydrothermal method. The catalyst exhibited a large surface area and good electron transmission efficiency, leading to efficient catalytic oxidation of toluene. The optimized catalyst outperformed noble metal-based catalysts by degrading 90% of 500 ppm-toluene at 180 degrees C. The study highlights the importance of carbon-based supports in promoting catalytic performance and offers potential for the development of high-performance transition metal oxide catalysts for volatile organic compound remediation.

Summary: In this study, three types of red-emissive carbon dots (RCDs) were successfully prepared with maximum emission at approximately 680 nm. The RCDs exhibited adjustable generation of reactive oxygen species (ROS) through type I and type II photodynamic therapy (PDT). The unique ROS formation of RCDs was determined by their core sizes and surface states, and they were able to induce cell programmed death via activating mitochondrion-mediated apoptotic pathways. This work provides a new prospect for RCDs as nanophotosensitizers to overcome the limitations of single type PDT.
