Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity.

Researchers demonstrate use of 3D printing to produce and operate light-weight, low-cost electrolyzers

Green Car Congress

The use of 3D printing allows construction of light-weight, low-cost electrolyzers and the rapid prototyping of flow field design. This development opens the door to the fabrication of light-weight and inexpensive electrolyzers as well as related electrochemical devices such as flow batteries and fuel cells, they suggested.

New ORNL non-precious metal catalyst shows promise as low-cost component for low-temperature exhaust aftertreatment

Green Car Congress

The new ORNL catalyst shows great potential as a low-cost component for the low temperature exhaust streams that are expected to be a characteristic of future automotive systems, the researchers noted in their paper in the journal Angewandte Chemie. The hundreds of species of hydrocarbons pose perhaps the biggest challenge.

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

When illuminated with light-emitting diodes rather than lasers, the photocatalytic efficiencies remain comparable, even when the scale of reaction increases by nearly three orders of magnitude. Unlike traditional catalysts, it doesn’t require heat; it harvests energy from light. —co-author Naomi Halas.
