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.

New iron catalyst helps preferentially reduce NO to hydroxylamine; pollution control and clean energy

Green Car Congress

Among the major pollutants, nitrogen oxide (NO x ) accumulation can cause severe respiratory diseases and imbalance in the Earth’s nitrogen cycle. Recently, the conversion of NO x into harmless or even useful nitrogen products has emerged as a promising strategy. An open-access paper on the work is published in Nature Communications.

Evonik and Siemens Energy commission pilot plant for conversion of CO2 to chemicals

Green Car Congress

Evonik and Siemens Energy commissioned a pilot plant—sponsored by the German Federal Ministry of Education and Research (BMBF)—that uses carbon dioxide and water to produce chemicals. The necessary energy is supplied by electricity from renewable sources. The pilot plant is located in Marl, in the northern Ruhr area.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. …
