Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Recent research in electrocatalytic CO 2 conversion points the way to using CO 2 as a feedstock and renewable electricity as an energy supply for the synthesis of different types of fuel and value-added chemicals such as ethylene, ethanol, and propane. Their paper is published in Proceedings of the National Academy of Sciences (PNAS).

US/China team develops robust, stable Ni/Fe OER catalyst for water-splitting at low overpotentials

Green Car Congress

A team from the University of Houston and Hunan Normal University in China has developed an active and durable oxygen evolution reaction (OER) catalyst for water splitting that meets commercial crtieria for current densities at low overpotentials. to deliver 200 mA cm -2 , unsatisfactory for the commercial requirements of 1.8-2.4

Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. Katarzyna P.

Researchers develop efficient single-atom Ni catalyst for conversion of CO2 to CO

Green Car Congress

While Ni metal catalyzes the hydrogen evolution reaction (HER) exclusively under CO 2 RR conditions, Ni single atomic sites present a high CO selectivity of 95% under an overpotential of 550 mV in water, and an excellent stability over 20 hours’ continuous electrolysis. The current density can be scaled up to more than 50 mA cm?2

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

New catalyst opens door to CO2 capture in coal-to-liquids process

Green Car Congress

World energy consumption projections expect coal to stay one of the world’s main energy sources in the coming decades, and a growing share of it will be used in CT—the conversion of coal to liquid fuels (CTL). The first stage in CTL is the conversion of coal to syngas—a mixture of carbon monoxide (CO) and hydrogen (H 2 ).

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

Researchers at Monash University in Australia are proposing a roadmap to renewable ammonia being produced in the future at a scale that is significant in terms of global fossil fuel use. Generation 3 avoids the need for the Haber-Bosch process entirely by direct electrochemical conversion of N 2 to NH 3.
