Catalytic oxidation of hydrogen on the surface of quartz, stainless steel, and MgO near the third ignition limit

The catalytic oxidation of hydrogen in a stainless steel reactor and in a MgO-coated quartz reactor near the third ignition limit was studied. The kinetic curves of heat release were found to be similar for these types of quartz reactor. The accompanying surface luminescence reaction with an intensi...

Description
Summary:	The catalytic oxidation of hydrogen in a stainless steel reactor and in a MgO-coated quartz reactor near the third ignition limit was studied. The kinetic curves of heat release were found to be similar for these types of quartz reactor. The accompanying surface luminescence reaction with an intensity maximum was recorded in the range 600–800 nm. A mechanism of heterogeneous oxidation of hydrogen with intermediate formation of hydrogen peroxide similar for the three surfaces was suggested.
