Abstract

A method is provided for producing a visual hydrogen sensor and to a sensor produced in this manner, the sensor allowing the presence of hydrogen gas in a medium to be detected by the naked eye as a result of a change of color in the sensor. The method involves the deposition of thin porous layers of oxides that do not absorb visible light in their completely oxidized state which become colored when they are partially reduced. This deposition is carried out using vapor phase deposition (PVD) in a glancing angle configuration (GLAD). The method also involves the preparation of a solution of an active metal precursor capable of dissociating the hydrogen molecule and a carrier vector and the deposition of this solution on the oxide layer in order to incorporate a minimum quantity of active metal within the pores of the oxide layer in the form of nanoparticles.
