    摘要: Disclosed is a hydrogen sensor. The hydrogen sensor includes a substrate; a color changeable layer disposed on the substrate and made of an oxide semiconductor material, wherein when the oxide semiconductor material reacts with hydrogen ions or hydrogen atoms, a color thereof changes; a catalyst layer disposed on a surface of the color changeable layer and made of a catalyst material, wherein the catalyst material dissociates hydrogen molecules (H2) into hydrogen atoms (H) or hydrogen ions (H + ); and a protective layer disposed to cover a surface of the catalyst layer and an exposed surface of the color changeable layer, and made of a polymer material, wherein the polymer material allows hydrogen molecules to pass therethrough but blocks water molecules.

    摘要: Die Erfindung betrifft ein standardisiertes Messverfahren zur Bestimmung der Photoaktivität von im sichtbaren Licht photokatalytisch wirkenden Materialien (vip-Materialien), insbesondere von vlp-Titandioxid sowie eine Messapparatur hierfür.
    Das vip-Material wird in der Lösung einer Testsubstanz, z.B. 4-Chlorphenol suspendiert, mit blau emittierenden Leuchtdioden (LED) belichtet und der Abbau der Testsubstanz wird über die Zeit gemessen. Die Messzelle ist so eingerichtet, dass eine Temperaturkonstanz für die LED-Belichtungsquelle und die Probe gewährleistet ist. Beispielsweise werden die LED mit maximal 50% der zulässigen Stromstärke betrieben.
    Das Messverfahren ist schnell und reproduzierbar durchführbar. Die Messapparatur ist kostengünstig und leicht zu transportieren
