UNSW Sydney team develops inexpensive water-splitting catalyst using 2D MOF framework array

Green Car Congress

UNSW Sydney chemists have fabricated a new, inexpensive catalyst for water splitting based on an ultrathin nanosheet array of metal-organic frameworks (MOFs) on different substrates. Unexpectedly, the integrated MOF electrodes demonstrate superior performances towards OER, HER and overall water splitting. —Duan et al.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. The research is outlined in a paper in Nature Energy. Beard and other NREL scientists in 2011 published a paper in Science that. Pach, Ashley R.

Tsinghua, MIT, Argonne team discovers lithium titanate hydrates for superfast, stable cycling in Li-ion batteries

Green Car Congress

An international research team from Tsinghua University, MIT and Argonne National Laboratory has discovered a series of novel lithium titanate hydrates that show better electrochemical performances compared to all the Li 2 O–TiO 2 materials reported so far—including those after nanostructuring, doping and/or coating. —Wang et al.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

A team of scientists at the University of Cambridge has reported the light-driven photoreforming of cellulose, hemicellulose and lignin to H 2 using semiconducting cadmium sulfide quantum dots in alkaline aqueous solution. The catalytic nanoparticles were added to alkaline water in which the biomass was suspended. Wakerley, Moritz F.

Rice, Lawrence Livermore scientists develop new efficient non-Pt MX2 catalyst for efficient hydrogen production; Materials Genome Initiative in action

Green Car Congress

Scientists at Rice University and the Lawrence Livermore National Laboratory have predicted and created new two-dimensional electrocatalysts—low-cost, layered transition-metal dichalcogenides (MX 2 ) based on molybdenum and tungsten—to extract hydrogen from water with high performance and low cost. —co-author Jun Lou.

TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

Green Car Congress

Researchers led by a team from Graz University of Technology (TU Graz) in Austria have shown that singlet oxygen ( 1 O 2 ) forms in the cathode of a Li–O 2 battery during discharge and from the onset charge, and that it is responsible for a major fraction of side products that cause fast ageing in the battery. —Mahne et al. 2017.36.
