High-entropy oxide as high-activity electrocatalyst for water oxidation

Green Car Congress

Researchers from the University of Twente in The Netherlands have developed a new high-entropy perovskite oxide (HEO) as a high-activity electrocatalyst for the oxygen evolution reaction (OER)—the key kinetically limiting half-reaction in several electrochemical energy conversion technologies, including green hydrogen generation.

KAUST team seeks improved catalysts for Lebedev ethanol-to-butadiene process for renewable rubber

Green Car Congress

The method involves combining solid catalyst precursors in water under continuous mixing. Now, researchers at KAUST, with colleagues in the Netherlands, are using solid-state nuclear magnetic resonance spectroscopy to study silica-magnesia catalyst formation under real wet-kneading conditions.

Study suggests energy and GHG impacts of synthetic hydrocarbon fuels from CO2 are greater than impacts of existing hydrocarbon fuels

Green Car Congress

Researchers at the Institute of Environmental Sciences at Leiden University, The Netherlands) have concluded that the energy demand and climate impacts of using CO 2 to produce synthetic hydrocarbon fuels by using existing technologies can be greater than the impacts of existing hydrocarbon fuels. —van der Giesen et al.

Researchers confirm existence of North Icelandic Jet current; implications for ocean response to climate change

Green Car Congress

As part of the planet’s reciprocal relationship between ocean circulation and climate, the AMOC transports warm surface water to high latitudes where the water warms the air, then cools, sinks and returns toward the equator as a deep flow. ” We present the first comprehensive measurements of the NIJ.

Researchers develop new catalysts for a direct Fischer-Tropsch to olefins (FTO) process

Green Car Congress

Researchers in the Netherlands have demonstrated the direct conversion of synthesis gas through a Fischer-Tropsch process to C 2 through C 4 light olefins with selectivity up to 60 wt.% The team formulated and tested their supported and bulk Fe catalysts in the FT reaction initially at 1 bar and 350°C at low CO conversion (0.5
