Graphite bet surface area
WebThe immobilization of the nZVFe particles onto RSAC leads to an increase in the BET surface area, as well as the pore volume of the nZVFe–RSAC. As mentioned earlier, the morphologies of RS, RSAC, ... and 2θ = 15.4° could be associated with the graphite structure, cellulose, and amorphous carbon in the carbonaceous material, respectively … WebAug 28, 2024 · When the BET equation is plotted, the graph should be of linear with a positive slope. If such a graph is not obtained, then the BET method was insufficient in obtaining the surface area. The slope and y-intercept can be obtained using least squares regression. The monolayer capacity X m can be calculated with 2.3.3 .
