Porous carbon refers to a class of carbon-based materials that feature a large number of internal pores. These pores can range from micropores (less than 2 nm) to mesopores (2–50 nm) and macropores (greater than 50 nm), giving the material an exceptionally high surface area. This internal architecture plays a vital role in enabling interactions with gases, liquids, ions, and molecules, making porous carbon incredibly functional.
Porous carbon can be derived from a variety of sources such as coconut shells, polymers, coal, biomass, or synthesized through chemical or physical activation methods. The material’s properties can be precisely tuned during production to suit specific applications, whether it’s conductivity, adsorption capacity, or pore size distribution.
One of the most impactful uses of porous carbon lies in energy storage devices such as supercapacitors and lithium-ion batteries.
Supercapacitors
Porous carbon is the most common electrode material in electrochemical double-layer capacitors (EDLCs). Due to its high surface area, it allows efficient charge accumulation at the electrode–electrolyte interface, enabling faster charging and discharging compared to traditional batteries.
Lithium-ion Batteries
In lithium-ion and sodium-ion batteries, porous carbon materials serve as anodes. Their porous structure accommodates the volume changes that occur during charge/discharge cycles, improving battery life and capacity. Furthermore, the conductive nature of carbon supports excellent electron transport.
Hydrogen Storage
Porous carbon is also being studied as a hydrogen storage material for fuel cell technologies. Its tunable pore structure enables the adsorption and storage of hydrogen under relatively mild conditions, making it attractive for future energy systems.
Porous carbon materials are extensively used in heterogeneous catalysis either as catalysts themselves or as supports for metal nanoparticles.
Their high surface area allows for excellent dispersion of catalytic particles.
Their chemical stability and conductivity enhance performance in electrochemical catalysis, such as oxygen reduction reactions (ORR) in fuel cells.
Activated porous carbon can serve as a solid acid or base for catalytic conversions in organic synthesis.
Additionally, porous carbon derived from biomass provides an eco-friendly alternative to traditional catalyst supports, aligning with global sustainability goals.
Due to its excellent adsorption characteristics, porous carbon is ideal for gas storage and separation processes.
CO₂ Capture
In carbon capture and storage (CCS) technologies, porous carbon is used to trap carbon dioxide emissions from power plants and industrial sources. Its high selectivity and adsorption capacity make it effective for reducing greenhouse gas emissions.
Natural Gas and Biogas Purification
Porous carbon is utilized in methane purification and biogas upgrading, selectively adsorbing impurities like H₂S, CO₂, and moisture. This improves the quality and calorific value of the final gas product.
Air and Gas Filters
Industrial and residential air purifiers often contain activated porous carbon filters to remove volatile organic compounds (VOCs), formaldehyde, and odors from the air.
Environmental cleanup is another vital area where porous carbon plays a transformative role.
Activated carbon filters are commonly used to remove heavy metals, organic pollutants, and chlorine from drinking water.
In wastewater treatment, porous carbon adsorbs dyes, pesticides, and industrial chemicals, restoring water quality.
Emerging applications include adsorption of microplastics and pharmaceuticals from water bodies.
Thanks to its eco-friendly nature and reusability, porous carbon is increasingly favored for sustainable environmental solutions.
Porous carbon materials are widely used in the field of chemical and biosensing. Their high surface area and conductivity enhance sensitivity and response time.
Gas sensors use porous carbon to detect harmful gases such as ammonia, NO₂, and CO at low concentrations.
Biosensors employ functionalized porous carbon to detect glucose, urea, cholesterol, and various disease biomarkers.
Porous carbon-based sensors are also being used in wearable electronics for real-time health monitoring.
The tunability of pore size and surface chemistry allows for the design of highly selective and reliable sensors.
In the biomedical sector, porous carbon materials are gaining traction due to their biocompatibility and non-toxic nature.
Porous carbon nanostructures are explored for targeted drug delivery, enabling controlled release and reduced side effects.
They can be engineered to release drugs in response to pH, temperature, or enzyme activity.
Their use in tissue engineering, wound healing, and diagnostic imaging is also under active research.
Moreover, carbon-based nanocarriers can bypass biological barriers, making them effective for cancer therapy and neurological drug delivery.
With the growing demand for electronic devices, EMI shielding has become a critical requirement in aerospace, automotive, and consumer electronics. Porous carbon composites offer lightweight, flexible, and high-performance solutions for absorbing electromagnetic waves, reducing signal interference, and protecting sensitive electronics.
Porous carbon materials, especially those derived from biomass or waste, are under development for carbon sequestration applications. Their ability to trap CO₂ molecules at low partial pressures and retain them over long durations makes them ideal candidates for geological or industrial carbon storage.
Functional porous carbon surfaces are designed to be superhydrophobic, repelling water while absorbing oils. This makes them suitable for:
Oil spill clean-up
Industrial oil-water separation
Protective clothing or coatings
With proper surface functionalization, these materials can even be reused multiple times, offering cost-effective and eco-friendly separation techniques.
Emerging applications of porous carbon include:
Flexible supercapacitors for wearable electronics
Self-powered sensors using triboelectric nanogenerators
Photothermal conversion materials for solar desalination
Carbon aerogels for aerospace insulation and thermal management
Research is ongoing, and the possibilities for innovation with porous carbon are nearly limitless.
