Abstract: The possibility of detection of methane using fiber-optical sensor with ZnO–SnO$_2$–Fe$_2$O$_3$C photocatalyst was demonstrated. Photocatalytic composite sensor element was prepared by non-isothermal polymer–salt method from solutions of inorganic metal salts and polyvinylpyrrolidone. Optical detection is carrying out by Bragg diffraction grating of fiber-optical sensor at the temperature variations during photocatalytic methane oxidation.

Keywords: methane, sensor, photocatalysis, fiber-optic sensor.
