Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. To make the material, nanospheres made of cobalt–nickel–glycerate are subjected to combined hydrothermal sulfidation and gas-phase phosphorization. Zhang, S.L., and Lou, X.W.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? 400 nm), the mesh produces hydrogen gas. Credit: ACS, Liu et al. Click to enlarge.

Siemens water purification unit generates enough methane to power its own operations; Singapore scaling up to larger pilot facility

Green Car Congress

A new biological water purification facility developed by Siemens generates enough methane gas to power its own operations. The pilot facility for this process, which is located at a site run by Singapore’s Public Utilities Board, has been operating in an energy-neutral manner since June 2010.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. Besides electricity, the study found that households exposed to air pollution consumed more natural gas. —Prof Salvo.
