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

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. —co-author Jeff Brinker, Sandia Fellow and University of New Mexico professor. Water splitting is a challenging reaction. It can be poisoned, stopping the molly reaction after some time period.

A closer look at why heat pumps are dominating EV HVAC systems

Charged EVs

Unfortunately, most vehicles of any kind have little or no insulation to prevent the gain or loss of heat from the cabin and, worse, the copious amounts of glass and metal comprising the vehicle body make an efficient collector (or radiator) of heat, bearing more than a passing resemblance to a solar thermal panel for heating water.

Microbial Capacitive Desalination Cell could make treatment and reuse of oil and gas wastewater simpler, cheaper

Green Car Congress

The saltiness of the water and the organic contaminants it contains have traditionally made treatment difficult and expensive. A description of the technology—microbial capacitive desalination—was recently published in an open access paper in the RSC journal Environmental Science Water Research & Technology as the cover story.

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. The US Department of Energy has set a goal of removing 90% of harmful emissions at 150 degrees Celsius or lower. Hensen, Yong Wang & Abhaya K.
