Technology of Application of the Multilayer Nanofilm ZIF-8/ZIF-67 for CO Detection

The process of the formation of gas-sensitive nanofilms ZIF-8 and ZIF-67 on substrates, which are glass chips with contact tracks formed on them, is studied. Multilayer ZIF-8/ZIF-67 nanofilms are grown on a substrate by cyclic layer-by-layer coating in solution. The film growth process is monitored...

Description
Summary:The process of the formation of gas-sensitive nanofilms ZIF-8 and ZIF-67 on substrates, which are glass chips with contact tracks formed on them, is studied. Multilayer ZIF-8/ZIF-67 nanofilms are grown on a substrate by cyclic layer-by-layer coating in solution. The film growth process is monitored after each cycle using X-ray diffraction, elemental analysis, and scanning electron microscopy. It is shown that at least three 30-minute growth cycles are required to form a strong, uniform ZIF-8 film. Additionally, the sensory properties of the obtained samples for the detection of carbon monoxide CO are studied.
