Researchers find isolated Pd atoms efficient low-temperature catalysts to convert CO in automotive exhaust

Green Car Congress

-alumina supports along with a small amount of lanthanum oxide can efficiently turn the carbon monoxide in automotive exhaust into carbon dioxide at temperatures as low as 40 ?Celsius, At low temperatures, carbon monoxide builds up on the catalyst, decreasing its efficiency. —Prof. alumina supports.

Mattershift scales up CNT membranes; potential for zero-carbon fuels for less than fossil

Green Car Congress

Startup Mattershift says it has achieved a breakthrough in making carbon nanotube (CNT) membranes at large scale. The paper is a characterization study of commercial prototype carbon nanotube (CNT) membranes consisting of sub–1.27-nm-diameter nm-diameter CNTs traversing a large-area nonporous polysulfone film.

U Wisc. scientists develop new method to convert lignin to simple chemicals under mild conditions

Green Car Congress

Researchers at the University of Wisconsin have disclosed a new method to convert lignin, an important component of biomass waste, into simple chemicals. Lignin, which accounts for nearly 30% of the organic carbon in the biosphere, is a complex material containing chains of six-carbon rings. —Shannon Stahl.

Rice University researchers create dual-purpose edge-oriented MoS2 film for energy storage, hydrogen catalysis

Green Car Congress

A new material developed at Rice University based on molybdenum disulfide (Mo S 2) exposes as much of the edge as possible, making it efficient as both a catalyst for hydrogen production and for energy storage. This converted the material to molybdenum disulfide without damage to its nano-porous sponge-like structure, they reported.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.

SUTD team proposes low-temperature thermionic converter with graphene cathode; about 45% efficiency

Green Car Congress

Thermionic energy converters are heat engines that convert heat directly to electricity at very high temperatures. A basic thermionic converter consists of two electrodes separated by a vacuum or a vapor. In 1915, Schlichter published an investigation into the use of thermionic emission for converting heat into electricity.
