Abstract

original image

A visible-light-responsive photocatalyst membrane, comprising only organic materials, degrades trimethylamine, a typical volatile organic compound, to CO2 with a quantum efficiency of ca. 40 %. The organic materials are phthalocyanine (p-type) and a perylene derivative (n-type), coated onto a Nafion membrane that serves as mechanical support and adsorbent material. The membrane uses natural light and ambient oxygen.
