UCLA team proposes non-photosynthetic biological conversion of CO2

Green Car Congress

Most of us naturally associate biological CO 2 conversion with photosynthesis in plants and algae. Furthermore, the maximum efficiency of solar energy conversion by photosynthesis is 5%, while typical solar panel efficiency reaches 20%. an and Park (2020) “Light-Independent Biological Conversion of CO 2 ,” Joule doi: 10.1016/ j.joule.2020.08.007.

Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

The efficient conversion of carbon dioxide, a major air pollutant, into ethanol or higher alcohols is a big challenge in heterogeneous catalysis, generating great interest in both basic scientific research and commercial applications. The key to this is the well-tuned interplay between the cesium, copper, and zinc oxide sites.

Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel heterostructured photocatalyst using titanium and copper, two abundant and relatively inexpensive metals, for the conversion of CO 2 into CH 4. Apart from its CO 2 conversion capabilities, the proposed photocatalyst has other benefits.

Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Green Car Congress

Researchers at Stanford University have shown that porous polymer encapsulation of metal-supported catalysts can drive the selectivity of CO 2 conversion to hydrocarbons. Using this technique, they report orders of magnitude higher turnover frequencies for hydrocarbon formation compared to conventional catalysts. Chengshuang Zhou, Arun S.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

The conversion normally requires significant amounts of energy in the form of high heat—a temperature of at least 700 ?C, The team tapped a novel energy source from the nanoworld to trigger a common chemical reaction that eliminates carbon dioxide. C, hot enough to melt aluminum at normal atmospheric pressure. —Renu Sharma.
