Special Issue Information

Dear Colleagues,

With the rapid development of industry and society, environmental issues, energy crisis, and resource scarcity have attracted ever-increasing concern. To create sustainable futures, a variety of new materials have been explored to date. At present, diversified porous materials such as traditional zeolites and activated carbon as well as emerging metal-organic frameworks have been developed due to the high specific area, large pore volume, and adjustable pore size. These porous materials have exhibited fascinating properties and promising applications in many fields. This Special Issue aims to cover studies on the synthesis and modification of diverse porous materials for applications in environment, energy, construction, and building engineering.

In this Special Issue, original research articles and reviews dealing with environmental remediation, energy storage, construction, and building engineering using a variety of porous materials are welcome. Contributions can be from different research backgrounds, including chemistry, environmental science, materials science, civil engineering, and so forth.

Research areas may include (but are not limited to) the following:

  1. Synthesis and applications of porous materials, such as zeolites, activated carbon, mesoporous materials, metal-organic frameworks, and covalent organic frameworks, for sustainable development;
  2. Porous materials for environmental application;
  3. Porous materials for energy storage;
  4. Porous materials for construction and building engineering;
  5. Reuse and recycling of industrial solid waste to varieties of porous materials.

I am looking forward to receiving your contributions.

The aim of this study is to improve the compressive strength of oil absorbent concrete (OAC) and to encourage its use in slope protection projects. This study used fly ash and slag produced in thermal power plants to substitute cement in significant amounts to prepare oil absorbent concrete (OAC). The water–cement ratios were set at 0.4, 0.5, and 0.6 and the sand rates were set at 30%, 35%, and 40% to investigate the effects of these factors on the oil absorption properties of the concrete, the variation of the oil absorption rate over time, and the compressive strengths at 28 days, 60 days, and 90 days. The compressive strength of oil absorbent concrete was improved by incorporating seashell powder (SC), alkali-modified seashell powder (SSC), and acid–base-modified seashell powder (CSC). The results showed that the optimal water–cement ratio for comprehensive oil absorption performance and compressive strength was 0.5, while the optimal sand ratio was 0.35. Compared with ordinary concrete, the oil absorption performance improved by 58.69%. The oil absorption rate decreased gradually over time. However, the oil absorption time could be effectively extended and the oil absorption performance could be improved by the addition of a silane modifier. The best method for seashell modification was acid–base modification. The compressive strength reached 14.32 Mpa at 28 days and 17.45 Mpa at 90 days, which was 19.62% higher than that of OAC. Scanning electron microscopy (SEM), mercury intrusion porosimetry (MIP), and X-ray diffraction (XRD) were used to analyze the microstructure of OAC. It was discovered that the inclusion of CSC caused a reaction with hydrocalumite in the concrete, resulting in the formation of alumohydrocalcite. Additionally, Ca(OH)2 in CSC facilitated the hydration reaction of mineral admixtures like fly ash and slag. At 28 days, more amorphous gels (C-S-H, C-(A)-S-H) and Aft were produced. The three components were combined to enhance the bonding between the cementitious materials and the aggregates, resulting in a denser internal structure of the OAC and improving its strength. This study promotes the use of OAC in slope protection projects. Full article

Construction and demolition waste residue soil (CDWRS) recycled foamed concretes were prepared by introducing the original CDWRS into modified binders. Pore structure, hardened performance, and sandwich wallboard application were also investigated. The results indicated that 51 kg/m3 of water glass and 7.5 kg/m3 of gypsum could significantly increase the strength and generate a slight influence on the thermal insulation performance of CDWRS recycled foamed concrete. The largest enhancing rate of 28-day compressive strength at a density of 600 kg/m3 could reach 205.5%. Foamed concrete with 1126 kg/m3 of CDWRS, modified with water glass and gypsum, showed a low thermal conductivity of 0.11 W/(m·K) and a dry density of 626 kg/m3. In total, 988 kg/m3 of CDWRS in foamed concrete led to a compressive strength of 7.76 MPa, a thermal conductivity of 0.14 W/(m·K), and a dry density of 948 kg/m3. Utilization of the foamed concrete in the sandwich structure could fabricate energy-saving wallboards with a minimum heat transfer coefficient of 0.75 W/(m2·K) and a relatively high compressive strength of 16.5 MPa, providing great confidence of CDWRS consumption in the building energy-saving field.

The present study investigates the adsorption of hydrogen gas by the Triassic Chang 7 Shale Member in the Ordos Basin, China. The mineral composition, microscopic morphology, pore characteristics, hydrogen adsorption capacity, and factors influencing hydrogen adsorption were explored using X-ray diffraction (XRD), thin section observations, nitrogen adsorption, scanning electron microscopy (SEM), and high-pressure hydrogen adsorption experiments. Based on these integrated tools, it was revealed that the Chang 7 Shale Member primarily comprises organic matter (kerogen) and clay minerals (predominantly an illite/smectite-mixed layer [I/S]). Nitrogen adsorption–desorption curves indicated the presence of slit-shaped pores, cracks, and wedge-shaped structures. The adsorption of hydrogen by shale decreases with increasing temperature and increases with increasing pressure. This adsorption behaviour conforms to both the Freundlich and Langmuir equations; moreover, the Freundlich equation provides a better fit. Organic matter (kerogen) and clay minerals considerably influence hydrogen adsorption. The present research provides insights into the occurrence of hydrogen in shale, offering implications for the exploration of natural hydrogen gas. Full article

The paper adopts an interdisciplinary approach to comprehensively review the current knowledge in the field of porous geological materials for hydrogen adsorption. It focuses on detailed analyses of the adsorption characteristics of hydrogen in clay minerals, shale, and coal, considering the effect of factors such as pore structure and competitive adsorption with multiple gases. The fundamental principles underlying physically controlled hydrogen storage mechanisms in these porous matrices are explored. The findings show that the adsorption of hydrogen in clay minerals, shale, and coal is predominantly governed by physical adsorption that follows the Langmuir adsorption equation. The adsorption capacity decreases with increasing temperature and increases with increasing pressure. The presence of carbon dioxide and methane affects the adsorption of hydrogen. Pore characteristics—including specific surface area, micropore volume, and pore size—in clay minerals, shale, and coal are crucial factors that influence the adsorption capacity of hydrogen. Micropores play a significant role, allowing hydrogen molecules to interact with multiple pore walls, leading to increased adsorption enthalpy. This comprehensive review provides insights into the hydrogen storage potential of porous geological materials, laying the groundwork for further research and the development of efficient and sustainable hydrogen storage solutions.
