Structural studies of microporous carbons by neutron diffraction

Neutron diffraction measurements have been made for a series of activated carbons of variable porosity. The results show that the structural features are unaffected by the degree of burn-off, despite a large variation in the small-angle scattering. Fourier transformation to a real-space distribution function gives well-defined peaks for the angle-averaged pair-correlation function. The first few peaks correspond to features within the lattice plane of graphite but there are deviations at larger values emphasising the defective nature of the microporous material.
