PXRD of the blends confirm that the amorphous nature of the starting materials was retained successfully for all compositions post heating (Figure ). The absence of significant Bragg peaks indicates no recrystallisation of either glass, or decomposition of the agZIF-62 to zinc oxide, occurred. As expected, the patterns resemble the inorganic PXRD more closely with increasing proportion of inorganic glass, accompanied by a concomitant decrease in intensity of the diffuse scattering features associated with agZIF-62 (2θ ~ 16° and ~ 33°).
