| description | The invention discloses a sensor device and method for monitoring the catalytic process of a photocatalyst in real time. The device comprises a conical micro-nanostructured optic fiber and a catalystnanoparticle layer; a transition region and a homogeneity region of the conical micro-nanostructured optic fiber form an interference structure, the conical micro-nanostructured optic fiber and a monomode optical fiber are welded to form an optical fiber sensing probe; the catalyst nanoparticle layer is fixed on the surface of the conical micro-nanostructured optic fiber to assemble a monofilm; the optical fiber sensing probe is soaked in a solution containing an organic molecule after the catalyst nanoparticle layer is fixed, the organic molecule is enriched on the surface of the conical micro-nanostructured optic fiber to form an organic matter interface layer, a light source is input into the conical micro-nanostructured optic fiber, and the photocatalytic process of the organic matterinterface layer is monitor |
