By organically integrating a solar tracking gimbal and a photochemical reaction system, a testing platform driven by outdoor sunlight for chemical reactions has been realized. The device structure is modularized to facilitate outdoor transportation and use. The flat photoreactor is adapted to the solar tracking gimbal and controlled via both light-sensing and manual modes, allowing the sunlight to remain perpendicular to the photoreactor at all times, thereby maximizing the efficiency of outdoor photochemical reactions. Additionally, the system is equipped with a material circulation setup to enable material recycling and gas separation, with vacuum applied to the solution vessel to promote more thorough gas-liquid separation. This device is mainly used for small-scale outdoor photochemical synthesis and catalytic gas production experiments.
Key Features
- High light-transmittance and corrosion-resistant flat photoreactor with adjustable liquid layer thickness;
