New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

Researchers produce green syngas using CO2, water and sunlight

Green Car Congress

Researchers from the University of Michigan and McGill University in Canada report photochemical syngas synthesis using a core/shell Au@Cr 2 O 3 dual cocatalyst in coordination with multistacked InGaN/GaN nanowires (NWs) with the sole inputs of CO 2 , water, and solar light.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting. 202300951

MIT researchers boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. The movement through water is sluggish, which slows the rate of conversion of the carbon dioxide.
