Chemically Activated Carbon Fibers (CAFs) were synthesized for ammonia adsorption. NH3 adsorption performance was measured in flowthrough configuration at both 0% and 50% relative humidity conditions. The surface of these materials was characterized using SEM, BET, elemental analysis, FTIR, XPS, and Boehm titration. High surface area >1000 m2/g of all ACFCs are essential to providing more accessible surface functional groups and thus adsorption efficiency. Surface chemistry analysis results showed that adsorption performance is correlated with surface acidic oxygen groups.
