Porous Materials for Energy and Environment Applications, 2nd Edition

Topic Information

Dear Colleagues,

In the past few decades, traditional fossil fuels, such as coal, oil, and natural gas, have been the biggest contributors to sustainable economic development in industrial sectors. However, the negative environmental and economic impacts of these fuels should be considered, as fossil fuels are the cause problems such as environmental pollution, global warming, and economic security. For example, due to the burning of hydrocarbon fossil fuels, CO₂ and other pollutant emissions are some of main contributors to atmospheric pollution and climate change. In order to cope with this crisis, porous materials for use in energy and environment applications are becoming a hot spot in industry and academia. An increasing number of researchers are entering the field, and the number of related papers is growing quickly. Thus, we are committed to providing a platform for the dissemination of high-quality papers in the field of porous materials for energy and environmental applications. This second edition is based on the successful first edition and continues to focus on fundamental and applied research on the use of porous materials to reduce CO₂ and pollutant emissions or to produce clean energy. Potential topics include, but are not limited to, the following:

• Porous materials for CO₂ capture and reduction;
• Porous materials for pollutant gas capture;
• Porous materials for photosynthesis and photocatalysis;
• Porous materials for clean energy;
• Porous materials for water purification.

The inherent brittleness of silica aerogels has hindered their application in thermal protection systems. To overcome this limitation, we developed a silica/polyimide composite aerogel with a bio-inspired “pomegranate-like” structure through in situ gelation. The strategic integration of polyimide nanofibers into the silica matrix created an interlocking network that immobilized silica particles, effectively resolving the mechanical fragility. By modulating the polyimide precursor (polyamic acid) concentration to 0.08 g/cm³ through polyimide nanofiber reinforcement, the compressive strength reached 2.86 MPa—12 times greater than that of unmodified silica aerogel. The material demonstrated multifunctional performance: exceptional flame resistance (withstanding 1300 °C flame for 20 min with self-extinguishing behavior), high hydrophobicity (123° water contact angle), and ultralow thermal conductivity (0.035 W/(m·K)). This synergistic combination of tunable mechanics, thermal stability, and insulation properties positions the composite as an advanced solution for next-generation thermal protection materials.
