About this Research Topic
Effective separation of gas mixtures plays an important role in tackling global energy and environmental challenges. Typical examples include the purification of fuel gases (e.g., natural gas, biogas, and hydrogen) for the clean energy sector, carbon dioxide capture for greenhouse gas mitigation and air separation for the production of medical oxygen and instrument gases. As well as paraffin/olefin separation to provide feedstock for chemical industry and the removal of toxic gases (e.g., sulfur dioxide, nitrogen dioxide, carbon monoxide, and volatile organic compounds) from air for the protection of the atmospheric environment. Each of the above processes represents an industry of billions of dollars and an economic pillar to the relevant government. The key to improving the efficacy of an adsorptive separation process is to provide high-performance adsorbents.
In recent years, we have witnessed explosive development of advanced porous adsorbents, including carbon-based materials (e.g., activated carbon, carbon nanotubes, and graphene), zeolites, metal-organic frameworks (MOFs) or porous coordination polymers (PCPs), covalent-organic frameworks (COFs) and their composites. Apart from that, new strategies emerged that enable the rational design and purpose-oriented tuning of the adsorbents, such as various post-synthesis techniques. This Research Topic aims to serve as a timely platform for discussion on recent advances in porous adsorbent development for energy and environment related separation applications, such as CO2 capture, volatile organic compounds (VOCs) removal, NOx/SOx abatement, and H2 purification.
Potential topics include, but are not limited to, the following:
• Adsorption fundamentals by molecular simulations in the design and development of adsorbents and novel experimental investigations
• Adsorption processes including pressure swing adsorption, temperature swing adsorption, and other novel adsorption processes, by both experimental investigation and computer modeling and optimization
• Hydrogen/methane storage
• CO2 capture
• VOCs removal
• NOx and SOx abatement
• H2 purification
• Novel adsorption-based gas or liquid separation (purification) processes
• Development of advanced porous adsorbents, including carbon-based materials (e.g., activated carbon, carbon nanotubes, and graphene), zeolites, metal-organic frameworks (MOFs) or porous coordination polymers (PCPs), covalent-organic frameworks (COFs), and their composites
• A review of the financial costs of deploying gas adsorption and separation processes for real-world applications
