研究目的
To present the simple manufacturing of an easy and economical UV-A photoreactor using a desktop 3D printer and its application in chemical transformations, specifically the photoreduction of benzophenone in high school laboratories.
研究成果
A low-cost, home-made, 3D-Printed UV-LED photoreactor was successfully used to perform the reductive homo-coupling of benzophenone to benzopinacol in high school laboratories, demonstrating the potential of 3D printing technology in educational settings.
研究不足
The device is limited to reactions that can be performed with UV-A light and may not be suitable for reactions requiring other wavelengths or more intense light sources.
1：Experimental Design and Method Selection:
The photoreactor was designed using Autodesk 123D Design software and printed using a Sharebot NG desktop 3D printer with PLA filament. UV-A LEDs were used as the light source.
2：Sample Selection and Data Sources:
A solution of benzophenone in 2-propanol was used for the photoreduction reaction.
3：List of Experimental Equipment and Materials:
Sharebot NG desktop 3D printer, Autodesk 123D Design software, PLA filament, UV-A LEDs, 2-propanol, benzophenone.
4：Experimental Procedures and Operational Workflow:
The photoreactor was printed, assembled with UV-A LEDs, and used to irradiate benzophenone solutions for varying durations.
5：Data Analysis Methods:
The formation of benzopinacol was observed visually and confirmed by TLC analysis.
