University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

Researchers at UC Santa Barbara develop efficient and stable plasmonic water splitter; potential alternative to semiconductor-based solar conversion

Green Car Congress

Researchers at UC Santa Barbara have developed an efficient, autonomous solar water-splitting device based on a gold nanorod array in which essentially all charge carriers involved in the oxidation and reduction steps arise from the hot electrons resulting from the excitation of surface plasmons in the nanostructured gold (plasmonic water-splitter).

New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

Politécnica de Valencia (Spain) have found that noble metal nanoparticles supported on titanium dioxide or cerium dioxide can catalyze the industrially important water gas shift (WGS) reaction for hydrogen production at ambient temperatures using visible light irradiation.

Duke team develops new core-shell copper nanowire catalyst for efficient water oxidation for solar fuels

Green Car Congress

A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodeposition of Ni or Co onto the surface of the nanowires. Water oxidation (2H 2 O → O 2 + 4 e- + 4H + ) is a key step for converting solar energy into chemical fuels. times more light. Chen et al. Click to enlarge.

Vertimass licenses ORNL ethanol-to-hydrocarbon conversion technology; overcoming the blend wall with drop-in fuels

Green Car Congress

In a 2012 presentation, the inventors said that the direct conversion process delivers a liquid hydrocarbon fuel yield of ~54-55% at 310°C, with ~6-7% ethylene and ~39% water byproducts, making the technology more cost-effective than previous approaches. Catalytic conversion of to hydrocarbons (2012). —Chaitanya Narula.

Honda opens Smart Home US in California; produces more energy than it consumes; direct DC-DC EV charging

Green Car Congress

The home’s occupant will be able to use less than half of the energy of a similarly sized new home in the Davis area for heating, cooling and lighting. The home is also three times more water-efficient than a typical US home. Advanced lighting. Therefore Honda Smart Home minimizes the use of blue light at night.
