Optical catalytic hydrogen production system by directly utilizing solar energy to decompose water

Abstract

This invention discloses a system for utilizing solar energy to catalyze and analyze water to produce hydrogen directly, in which, a gas chromatograph, a flowmeter and a gas collecting bottle are connected orderly on the exit of the top of a liquid tank, a circulation pump is connected at the bottom, one end of a light-catalyzed reactor is connected to the pump and the other end is connected to the liquid tank set with a temperature probe and a precision pressure meter on the wall, in which, the included angle of the slant and the level of the stainless steel frame is a, which is the latitude at the spot, at least one compound paraboloid optical collector is set on the slant fixed by a bearing, the collectors are connected by screws, and a pipe reactor is set at the center of each of the collectors and serial together by PVC tubes.

Description

technical field [0001] The invention belongs to the field of large-scale preparation of renewable energy, and relates to a device for producing hydrogen by photocatalytically decomposing water under direct solar light and a hydrogen separation and collection device, in particular to a system for producing hydrogen by directly utilizing solar photocatalytically decomposing water. Background technique [0002] Insufficient supply of conventional primary energy, severe pollution caused by the use of fossil energy, and energy problems in rural and remote areas have put my country under multiple pressures, prompting people to look for new clean alternative energy. Hydrogen is odorless and non-toxic, and the product after combustion is water and non-polluting. It is convenient to store and transport, and easy to regenerate. It has been generally regarded as the most ideal pollution-free green energy in the new century. At present, the international community has been vigorously pr...

Problems solved by technology

[0004] Retrieval, review of relevant literature, patents and other materials found that there are currently many reports on photocatalytic hydrogen production reactions, but due to limitations in experimental equipment and other conditions, most of these systems use xenon lamps, tungsten lamps and other simulated solar light sources for experiments, and cannot directly Effective use of solar energy

In the field of photocatalysis, the application of solar energy is mainly limited to photocatalytic degradation of organic matter, but there is no official report on the direct use of solar energy to photocatalytically split water to produce hydrogen.
