Summary: This study investigates the importance of the interaction and position of the nitro group in the adsorption of 2-nitrophenol (2-NP), 4-nitrophenol (4-NP), and phenol by demineralized kraft lignin activated carbon (DKLAAC). The results show that the adsorption follows the order 2-NP > 4-NP > phenol, and both solubility and donor-acceptor complex mechanism play a significant role in the adsorption process. The experimental data fits well with the Langmuir adsorption isotherm and pseudo-second order kinetic models. The temperature study reveals that the adsorption process is endothermic and spontaneous with high affinity between DKLAAC and phenols.

Summary: Nitrogen-doped activated carbons are gaining increasing interest in environmental protection, pharmaceutical, and food industries due to their tunable pore structures, surface functional groups, and variable charges. This study produced a low-cost nitrogen-doped activated carbon derived from kraft lignin in black liquor using a self-activation method and demonstrated its efficacy as an adsorbent for anionic methyl orange. The activated carbon exhibited a rich pore structure, with a specific surface area of 1124.78 m2 g-1 and a total pore volume of 0.60 cm3 g-1. Under optimized conditions, it showed a maximum adsorption capacity of 373.95 mg g-1 for methyl orange in simulated wastewater. The adsorption process followed the Pseudo-second-order kinetic model and the Langmuir model. This research provides a novel strategy for producing low-cost lignin-derived activated carbon from dried black liquor through self-activation.

Summary: The catalytic activity of a zero valent nickel complex (Ni-comp) derived from a metal-organic framework precursor supported over aluminum oxide/lanthanum oxide-cerium dioxide (ALC) for acetic acid steam reforming was studied. The Ni-comp/ALC catalyst exhibited almost complete conversion of acetic acid to hydrogen alongside some impurities. The 15 wt% Ni catalyst showed the highest hydrogen yield and maintained sufficient stability over 40 hours of reaction time. Ni-comp-ALC interactions were found to improve the activity and stability of the catalyst by preventing coke deposition and metal sintering.

Summary: The synergistic effect of 'reactive adsorption and catalytic oxidation (RACO)' was investigated using an amorphous-manganese dioxide-activated carbon (Am-MnO2-AC) composite for the removal of volatile organic compounds (VOCs: formaldehyde (FA) + toluene). The RACO performance of Am-MnO2-AC was found to be highly efficient in removing FA and toluene, achieving complete oxidation into carbon dioxide (CO2). The enhanced performance was attributed to the higher surface porosity and concentration of oxygen vacancies in Am-MnO2-AC. This study provides insights into the practical application of metal oxide/AC composites for improving indoor air quality.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
