The composition, optimal proportions and technology for the preparation of thin gaseous nanocomposite films were developed, which emit
components with selective detection of natural gas in a wide range of concentrations with the participation of a template and a template based on
tetroethoxysilane and metal oxides, highly sensitive to natural gas were created on the basis of these films and selective semiconductor sensors (SCS) were manufactured. The use of ready-made sensors as part of alarms and gas analyzers is desirable because of their high sensitivity, selectivity and signal stability with continuous automatic detection of natural gas.
