Energy Conversion and Catalytic Materials Engineering Lab
Machine-translated · View original
The lab studies artificial photosynthesis, using sunlight to turn water and carbon dioxide into fuel.
AboutAbout the lab
Making fuel from sunlight.
The Wang Lab studies the materials, methods, and technologies needed to produce renewable fuels from solar energy through artificial photosynthesis.
Inspired by photosynthesis in plants, the lab designs and builds photocatalytic systems that use sunlight to convert water and carbon dioxide into hydrogen and carbon-containing fuels.
Beyond understanding the chemistry of photocatalysts, the lab also places importance on demonstrating scalable approaches to producing solar fuels at a practical scale.
The research connects with many fields, including materials engineering, chemistry, semiconductor physics, and chemical engineering.
Key terms
- Artificial photosynthesis
- Technology that, like photosynthesis in plants, uses the energy of sunlight to produce fuels and chemicals from water and carbon dioxide
- Photocatalyst
- A material that, when exposed to light, drives chemical reactions in surrounding substances without itself being changed
- Band gap
- The range of energy a semiconductor needs in order to absorb light and move electrons. The narrower it is, the more colors of light it can use

Inspired by photosynthesis in plants, the lab designs and builds photocatalytic and photoelectrocatalytic systems that use sunlight to convert water and carbon dioxide into hydrogen and carbon-containing fuels. It aims to realize scalable artificial photosynthesis systems for the practical, sustainable production of solar fuels.
*Illustrative imageNew photocatalysts that can use more light
Using photocatalysts with narrow band gaps is key to producing solar fuels. Through approaches such as valence band control and doping, the lab aims to raise the efficiency with which photocatalysts use sunlight.
*Illustrative imageNew devices based on photocatalysts
Creating artificial photosynthesis systems that are efficient and easy to scale up is a central challenge for producing solar fuels in large quantities. The lab designs and develops new devices, such as photocatalyst sheets, aiming for efficient solar fuel production.
*Illustrative imageHybrid systems for selective CO2 conversion
Systems that convert CO2 into fuels and chemicals are a major challenge for achieving carbon neutrality. By methods such as attaching catalyst molecules to photocatalyst sheets, the lab is exploring new ways to selectively produce targeted products from CO2 reactions.
