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

Green Car Congress

The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap. Molly is dirt cheap and abundant. —Stan Chou. People want a non-platinum catalyst. Luk, Bryan Kaehr & C.

China’s EV market hits its stride with 1-in-3 sales being electrified

Teslarati

The top spot, as expected by anyone who has watched the Chinese market, was the Wuling HongGuang Mini EV , a cheap and practical EV made by none other than a joint venture with General Motors (the company that sold 26 EVs in the US Q4 2021 ), SAIC Motors, and Liuzhou Wuling Motors.

The Coming Construction Boom

Cars That Think

Now, with 3D printing along with general-form geometric CAD, new shapes will become possible even for low-cost buildings. Imagine using cheap wind- and solar-generated electricity to pull carbon out of the atmosphere and turn it into feedstock for large-scale 3D printing of building components.

KTH team develops new cost-effective water-splitting electrocatalyst for H2 production

Green Car Congress

The new catalyst also offers a competitive, cheap alternative to catalysts that rely on more expensive, precious materials, such as iridium oxide (IrO 2 ) or ruthenium oxide (RuO 2 ). Water splitting is considered one of the most promising strategies to produce chemical fuels such as hydrogen.

Stanford, SLAC team cages silicon microparticles in graphene for stable, high-energy anode for Li-ion batteries

Green Car Congress

The method can be applied to other electrode materials, too, making energy-dense, low-cost battery materials a realistic possibility. There are huge challenges associated with using low-cost,micrometre-sized Si source materials. —Yi Cui. Here we introduce a method to encapsulate Si microparticles (∼1–3 µm).

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

Green Car Congress

Herein, we propose a facile and low cost alternative to production of nano-Si with excellent electrochemical performance using a highly abundant, non-toxic, and low cost Si precursor: sand. . … Recently, magnesiothermic reduc- tion has gained attention due its much lower operating temperatures (~650 ?C).
