Abstract:
1. A process for photolyzing water comprising the steps of: placing a photolytic layer provided with a light-transmissive porous material and a photocatalyst supported on the porous material on a water layer containing water in its liquid state with a first space layer filled with air therebetween; shining light onto the photolytic layer; and separating vapor generated from the water layer into hydrogen and oxygen by the photocatalyst, which is excited by the incident light, when the vapor is introduced to the photolytic layer via the first space layer, wherein the porous material has a 3-dimensional reticulated skeleton and supports photocatalyst particles, and wherein the porous material surface is water-repellent.
