Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.

An
international team of researchers has discovered how adding trace
amounts of water can tremendously speed up chemical reactions—such as
hydrogenation and hydrogenolysis—in which hydrogen is one of the
reactants, or starting materials. Previous research had indicated this
phenomenon, but until now the true importance of water to its effect has
eluded chemists.

A
detailed description of development of the first practical device that
mimics the process of photosynthesis has recently been published in an
American Chemical Society journal. Unlike earlier devices, which used
costly ingredients, the new device is made from inexpensive materials
and employs low-cost engineering and manufacturing processes.

Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential. Now, scientists at Brookhaven National Laboratory have developed a new electrocatalyst that addresses one of these problems by generating hydrogen gas from water cleanly and with much more affordable materials.

Engineers
at Stanford University have found a novel method for “decorating”
nanowires with chains of tiny particles to increase their electrical and
catalytic performance. The new technique is simpler, faster and
provides greater control than earlier methods and could lead to better
batteries, solar cells and catalysts.

Scientists
in Sweden say they have developed a molecular catalyzer with the
ability to oxidize water to oxygen at speeds comparable to those in
nature's own photosynthesis. This finding would be a world record for
artificial photosynthesis.

In
prototypes of the lithium-sulfur battery, lithium ions are exchanged
between lithium- and sulfur-carbon electrodes. The sulfur is an
excellent energy storage material due to its low weight. At the same
time, sulfur is a poor conductor, so researchers have a devised a way to
greatly improve conductivity using a porous network of carbon
nanoparticles.

Researchers
at the Massachusetts Institute of Technology have combined gold
nanoparticles with copper nanoparticles to form hybrid nanoparticles.
Transformed into a powder they can catalyze a carbon dioxide reduction
that uses less energy than previous methods and may help reduce
emissions of greenhouse gases at powerplants and other point sources.

A
newly developed combination device for infrared spectroscopy has
allowed researchers in Germany to conduct highly precise measurements of
the vibration frequency of oxide materials at the surface. Surface
defect analyses have previously been well-documented for metals, but
materials such as titanium dioxide haven’t before been studied in such
detail.

Scientists
long have known that butterfly wings contain tiny scales that serve as
natural solar collectors to enable butterflies, which cannot generate
enough heat from their own metabolism, to remain active in the cold.
Scientists in China have used this same structure, taken from a black
butterfly to create a titanium dioxide-based device catalyst that
significantly improved hydrogen production.
