As a highly adsorbent material, activated carbon continues to show unique value in environmental protection, energy development and other fields due to its developed pore structure and huge specific surface area (usually up to 500-1500 m²/g). Its preparation raw materials include renewable resources such as coconut shells, wood, and coal, and its green characteristics make it an important material for sustainable development.
1. Core application areas
Environmental governance
Water treatment: can remove heavy metals (such as lead, mercury) and organic pollutants, and activated carbon filters are commonly used in municipal water supply systems
Air purification: adsorbs indoor pollutants such as formaldehyde and VOCs, and the adoption rate of vehicle air filters is over 80%
Medical health
First aid detoxification: prevents the absorption of poisons through surface adsorption
Blood purification: key filter medium in artificial kidney devices
Industrial catalysis
As a catalyst carrier, it is widely used in:
\ce{2SO2 + O2 ->[activated carbon] 2SO3}
and other chemical reactions, which is about 40% more efficient than traditional carriers
2. Frontier research directions
Structural regulation
Develop hierarchical pore structure materials to simultaneously improve microporous adsorption and mesoporous mass transfer efficiency
The specific surface area of graphene composite carbon materials exceeds 3000 m²/g
Regeneration technology
