New high-activity, low-cost nickel-based catalyst for fuel cells exhibits performance similar to Pt; hydroxide exchange membrane fuel cells

Green Car Congress

Researchers at the University of Delaware, with a colleague at the Beijing University of Chemical Technology, have developed a composite catalyst—nickel nanoparticles supported on nitrogen-doped carbon nanotubes—that exhibits hydrogen oxidation activity in alkaline electrolyte similar to platinum-group metals.

Who Will Free EV Motors from the Rare Earth Monopoly?

Cars That Think

Ayman El-Refaie, Marquette University Now a sleeper option, synchronous reluctance motors , is getting a surge of interest, thanks to materials-science breakthroughs at GE Aerospace. GE Aerospace declined to make a researcher available to be interviewed for this article.) I am a believer that this type of material is a game changer.”

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

Nevertheless, because of the scarcity and cost of Pt, a more abundant alternative is needed for cost-effective implementation. —co-author Jeff Brinker, Sandia Fellow and University of New Mexico professor. But getting inexpensive molly to work this much more efficiently could drive hydrogen production costs way down.

High capacity, long-life porous nano-silicon Li-ion anode material from beach sand

Green Car Congress

Researchers at the University of California, Riverside’s Bourns College of Engineering have synthesized a porous nano-silicon material from beach sand (SiO 2 ) via a highly scalable heat scavenger-assisted magnesiothermic—i.e., using a combination of heat and magnesium—reduction. —Favors et al. —Favors et al.

New bimetallic copper-titanium hydrogen evolution catalyst outperforms platinum by more than 2x

Green Car Congress

Regardless of acidic or basic conditions, Pt, along with its alloys, is the benchmark electrocatalyst that requires very small overpotentials to drive the reaction, whereas the scarcity and high cost of Pt hinder its large-scale use for H 2 production. … The two Cu-Cu-Ti hollow sites exhibit HBE values close to that of Pt.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes).
