The influence of iodine donor forms on the characteristics of sedimentation-forming AgI-MСM48-MeIx hybrid powders

AgI-МСМ48-MeIx hybrid powders (HPs) were prepared by the method of Hydrothermal template co-condensation. Silver iodide was always a product of the reaction between silver nitrate and potassium iodide. But metal iodide (copper iodide or zinc iodide) was a native substance or a result of the reaction between metal nitrate and potassium iodide. There were 2 ways to form metal iodides in the reaction solution. The effect of the metal iodide form (nitrate or iodide one) on the structural, textural, morphological, and rheological properties of the HPs has been studied. Much attention was paid to the thermal stability of silver iodide in the hybrids with the introduction of additional iodine donors - copper iodide or zinc iodide (through their nitrate or iodide form). It has been shown that the nitrate form of metal iodide (regardless of the type of cation) makes it possible to preserve the development of the powder agglomerate surface to a greater extent. It is noted that when using zinc iodide as an iodine donor, the amount of silver iodide in the hybrid composition was greater than with copper iodide or in the complete absence of an iodine donor.
