Efficiency of Novel Photocatalytic Coating and Consolidants for Protection of Valuable Mineral Substrates.

In the process of protection and consolidation of valuable materials, the efficiency is the crucial property that needs to be considered. TiO₂/ZnAl layered double hydroxide (LDH) coating and silicate- and carbonate-based consolidants were synthesized and proposed to be used for protection and consolidation of four porous mineral substrates: brick, stone, render and mortar. The photocatalytic efficiency of TiO₂/ZnAl LDH coating, as well as consolidation efficiency of two consolidants, both applied on model substrates, were studied.
