Abstract

The invention discloses an efficient photo-catalytic reactor which comprises an upper cover plate and a base. The upper cover plate is arranged on the base, the efficient photo-catalytic reactor is characterized in that a first rectangular concave plane is formed in the upper end surface of the base, conducting glass is placed in the first rectangular concave plane, and a photocatalyst is arranged on the upper surface of the conducting glass; the photocatalyst is a nanorod array thin film photocatalyst; a second rectangular concave plane is formed in the lower end surface of the upper cover plate and corresponds to the first rectangular concave plane in position; an inverted micro boss array is arranged in the second rectangular concave plane; the upper cover plate is provided with a fluid inlet and a fluid outlet, and the fluid inlet and the fluid outlet communicate with the second rectangular concave plane through micro fluid input channels and micro fluid output channels correspondingly; and the micro fluid input channels and the micro fluid output channels are formed in the upper cover plate. The efficient photo-catalytic reactor provided by the invention is simple in structure, easy to mount, low in cost, high in reaction efficiency and capable of being widely applied to the fields of energy, environment protection and the like.

Description

technical field [0001] The invention relates to a reactor, in particular to an efficient photocatalytic reactor. Background technique [0002] Environmental pollution and energy crisis have become two major problems in the development of human society. As a green technology with important prospects in the field of energy and environment, photocatalytic technology has attracted great attention of researchers. Photocatalysis is a new technology that uses semiconductor materials as catalysts to convert light energy into chemical energy. The basic principle of photocatalyst: Under the light radiation of a specific wavelength range, the semiconductor material used as a photocatalyst is excited to generate photo-generated electrons. , bacteria, viruses and other reactions. At present, photocatalytic technology has been used in wastewater treatment, water splitting hydrogen production, photocatalytic fuel cells and photocatalytic reduction of CO 2 etc. have been widely used. ...
