Abstract
Provided are a device for hydrogen production from water photolysis and a method therefor, which belongs to the field of photocatalytic solar hydrogen production. The device for hydrogen production from water photolysis comprises: a catalytic reaction unit for water photolysis comprising a light-transmitting surface, and a light condenser component with a light-concentrating surface facing the light-transmitting surface of the catalytic reaction unit for water photolysis; the light condenser component comprises a solar concentrating cone and a reflector for reflecting and concentrating sunlight into the solar concentrating cone. In the present application, from the perspective of improving the utilization efficiency of sunlight, the device for hydrogen production from water photolysis is designed, which utilizes the light condenser component to concentrate solar energy into the catalytic reaction unit for water photolysis, greatly improving the light intensity and catalytic efficiency, and greatly simplifying the catalytic interface and reaction unit for water photolysis.
