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).

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. Chen et al. Click to enlarge. times more light.

University of Texas researchers develop new solar photoelectrosynthetic process to convert CO2 to methanol

Green Car Congress

Researchers from The University of Texas at Arlington are developing a new process for photoelectrosynthesis of methanol—the conversion of carbon dioxide to methanol using sunlight and hybrid CuO–Cu 2 O semiconductor nanorod arrays. In the lab, they submerged those rods in a water-based solution rich in CO 2.

Researchers develop high-rate, high-yield bacterial process to convert methane to methanol

Green Car Congress

Researchers at Columbia University have developed a biological process utilizing autotrophic ammonia-oxidizing bacteria (AOB) for the conversion of methane (CH 4 ) to methanol (CH 3 OH). The maximum specific rate of CH 4 to CH 3 OH conversion obtained during this study was 0.82 Cartoon of the process. Click to enlarge.
