This paper presents a systematic approach to the development of novel solid-state chemical sensors on the basis of heterogeneous chemiluminescence. The method is applicable for the identification and measurements of concentration of H, O, and other gaseous chemical radicals, where utilization of standard techniques is difficult. The luminescence is invoked(More)
We report on the effect of temperature on the electric current induced in the mesoporous Pt/TiO2 structure by the room temperature surface chemical reaction of hydrogen and oxygen,13,14 which helps to unveil the physical origin of this current and the related electromotive force (chemi-EMF). We found that the temperature dependence of this reaction current(More)
There have been many works analyzing thermionic currents and chemicurrents generated on various electrolyte-free metal/semiconductor nanostructures. More recently, the chemicurrent phenomenon was reported for mesoporous Pt/semiconductor systems adept at converting surface-released chemical energy into a stationary electrical signal at room-temperature(More)
