Artificial Photosynthesis

Location: N3.1-B3a-02

The Artificial Photosynthesis Research Laboratory focuses on producing hydrogen and oxygen through the splitting of water molecules with solar energy. In order to achieve this goal, the laboratory explores different approaches in materials fabrication and device design. Some of the approaches include the synthesis of composite nano-photocatalysts, fabrication of metal-semiconductor hetero-nanostructures, optimization of photoanodes/photocathodes for photo-electrochemical (PEC) water splitting and modification of semiconductor photocatalysts by dye sensitization or doping.

Common research facilities include the high speed bench-top centrifuge, ultra-low temperature freezer, ice flake maker, vacuum oven, nitrogen dry glove box, and ultrapure water system.

Materials synthesis and fabrication facilities include the microwave reactor, high-pressure stirred reactor with controller, programmable vacuum spin coater, electrospinning machine, and air forced oven.

Facilities for photo-illumination and gas evolution include the photochemical reactor system, UV-Vis-NIR spectrophotometer, electrochemical workstation, halogen lamps, solar simulators, 300 W and 500 W Xenon lamp illuminators, recirculating chiller and evaporator, hydrogen generator and gas chromatography system.
