Volumetric and Gravimetric BET Surface Area Determinations,
Abstract
Methods of determining surface areas with both a commercially available volumetric BET (Brunauer, Emmetl, and Teller) apparatus and an in-house gravimetric BET apparatus have been evaluated and compared. Results of determinations on standard materials show that both methods are accurate to within 10 percent of accepted literature values. Correlations between the two methods and with Double Layer Capacitance (DLC) results show that the two BET methods agree within experimental error and give results similar to the DLC data. The advantages of each BET method and recommendations for their future use are discussed. (Author)
