Summary: Injecting CO2 into shale reservoirs has dual benefits for enhancing gas recovery and CO2 geological sequestration, which is crucial for China's energy security and carbon neutrality goals. This study investigates the CO2 adsorption mechanism in shales using isothermal adsorption measurement and petro-physical characterization methods. The results show that the sorption capacity of CO2 in shales increases gradually with injection pressure and can be described by the Langmuir model. Organic carbon content is the most significant control factor, along with other secondary factors such as vitrinite reflectance, clay content, and brittle mineral content. The research findings can be applied to evaluate the potential of CO2 geological storage in shales.

Summary: Porous graphene materials (PGMs) with different morphologies and pore structures can be prepared through CO2 and KOH activation of thermal exfoliated graphene oxide, exhibiting rich surface chemistry properties. The specific surface areas and pore volumes of PGMs can be easily tuned by adjusting the activation conditions, affecting their gas adsorption performance significantly. Experiment results demonstrate that the gas adsorption of PGMs is influenced by both their pore structure and surface chemistry, showing potential applications in gas storage and separation technologies.

Summary: The study investigated the impact of supercritical CO2-water exposure on the adsorption characteristics of shale, revealing that increasing exposure pressure and decreasing exposure temperature resulted in a gradual decrease in CH4 and CO2 adsorption capacity in shale due to alterations in mineral composition and pore structure. The study also found that the selectivity factor of CO2 to CH4 decreased with increasing exposure pressure and decreasing temperature, indicating the feasibility of CO2-enhanced shale gas recovery and sequestration even after exposure to ScCO2-water.

Summary: Li2CO3- and (Li-K)(2)CO3-based porous carbon composites were synthesized from terephthalic acid, lithium hydroxide, and sodium hydroxide through calcination at different temperatures. Characterization results showed that LiC-700℃ and LiKC-600℃ exhibited excellent CO2 capture capacities of 140 mg CO2 g(-1) at 0℃ and 82 mg CO2 g(-1) at 25℃, respectively. The selectivity of LiC-600℃ and LiKC-700℃ towards a CO2/N2 (15:85) mixture was calculated to be approximately 27.41 and 15.04, respectively, indicating their high potential for CO2 capture.

Summary: In the process of hydraulic fracturing, the pore structure and gas adsorption/desorption characteristics of coal samples are affected. This study found that clean fracturing fluid treatment can increase the micropore volume and specific surface area of coal samples, enhancing both the adsorption and desorption capacity of methane. The degree of influence varies among different rank coals, with low-ranking coals experiencing a decrease in desorption capacity due to the increase in micropores.

Summary: In this study, a sludge-activated carbon adsorbent with CO2 adsorption capacity was prepared by pyrolysis and activation of municipal sewage sludge, and then the activated carbon was modified to increase its CO2 adsorption capacity. The results showed that modification with hydrofluoric acid and sodium hydroxide increased the specific surface area and pore volume of the activated carbon, while modification with aminopropyl triethoxysilane-diethanol monoisopropanolamine reduced these properties. The modifications had a significant impact on the saturated adsorption capacity, and the promoting pressure thresholds were determined for each modification method.

Summary: This paper proposed a microstructural analysis for coal-rock based on low-field nuclear magnetic resonance (LNMR) technology, the L-weighing method, to accurately and quantitatively characterize the evolution of coal microstructures before and after supercritical CO2 treatment. The experimental results of the L-weighing method and the LNMR method were compared and analyzed, and it was found that there were differences between the two methods but the overall laws were basically the same. The L-weighing method quantitatively characterizes the water content in coal and determines water consumption and microscopic component extraction in coal with supercritical CO2, while the LNMR method only determines the dissolution of H-containing substances in the coal by supercritical CO2. According to the combined analysis with the L-weighing method and the LNMR method, it was found that the supercritical CO2 treatment led to water consumption, extraction of microscopic components, volume expansion, permeability increase, and pore connectivity increase in the coal microstructure.

Summary: In this study, an eco-friendly and highly efficient biohybrid photocatalyst, carbonized rape pollen confined Cu2O nanoparticles (Cu2O/BC), was fabricated for the photodegradation of tetracycline under visible-light illumination. The Cu2O/BC exhibited excellent photocatalytic activity, with a degradation rate roughly 6.0 and 3.2 times higher than BC and Cu2O, respectively. The enhanced performance was attributed to the construction of a heterojunction, promoting the effective separation of photogenerated carriers, and the three-dimensional hollow BC providing structural stability for Cu2O. This work provides crucial insights into the utilization of nature-based biological materials in efficient antibiotic removal and environmental remediation.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
