Nanotechnology engineering produces a water splitter that runs on an ordinary AAA battery

National Nanomanufacturing Network - August 27, 2014 - 4:56am
In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming. Now scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron. "Using nickel and iron, which are cheap materials, we were able to make the electrocatalysts active enough to split water at room temperature with a single 1.5-volt battery," said Hongjie Dai (http://dailab.stanford.edu/), a professor of chemistry at Stanford. "This is the first time anyone has used non-precious metal catalysts to split water at a voltage that low. It's quite remarkable, because normally you need expensive metals, like platinum or iridium, to achieve that voltage." In addition to producing hydrogen, the novel water splitter could be used to make chlorine gas and sodium hydroxide, an important industrial chemical, according to Dai. He and his colleagues describe the new device in a study (http://dx.doi.org/10.1038/ncomms5695) published in the Aug. 22 issue of the journal Nature Communications. The promise of hydrogen Automakers have long considered the hydrogen fuel cell a promising alternative to the gasoline engine. Fuel cell technology is essentially water splitting in reverse. A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity, which powers the car. The only byproduct is water – unlike gasoline combustion, which emits carbon dioxide, a greenhouse gas.Earlier this year, Hyundai began leasing fuel cell vehicles in Southern California. Toyota and Honda will begin selling fuel cell cars in 2015. Most of these vehicles will run on fuel (http://energy.gov/eere/fuelcells/natural-gas-reforming) manufactured at large industrial plants that produce hydrogen by combining very hot steam and natural gas, an energy-intensive process that releases carbon dioxide as a byproduct. Splitting water to make hydrogen requires no fossil fuels and emits no greenhouse gases. But scientists have yet to develop an affordable, active water splitter with catalysts capable of working at industrial scales. "It's been a constant pursuit for decades to make low-cost electrocatalysts with high activity and long durability," Dai said. "When we found out that a nickel-based catalyst is as effective as platinum, it came as a complete surprise." Saving energy and money The discovery was made by Stanford graduate student Ming Gong, co-lead author of the study. "Ming discovered a nickel-metal/nickel-oxide structure that turns out to be more active than pure nickel metal or pure nickel oxide alone," Dai said. "This novel structure favors hydrogen electrocatalysis, but we still don't fully understand the science behind it." The nickel/nickel-oxide catalyst significantly lowers the voltage required to split water, which could eventually save hydrogen producers billions of dollars in electricity costs, according to Gong. His next goal is to improve the durability of the device. "The electrodes are fairly stable, but they do slowly decay over time," he said. "The current device would probably run for days, but weeks or months would be preferable. That goal is achievable based on my most recent results" The researchers also plan to develop a water splitter than runs on electricity produced by solar energy. "Hydrogen is an ideal fuel for powering vehicles, buildings and storing renewable energy on the grid," said Dai. "We're very glad that we were able to make a catalyst that's very active and low cost. This shows that through nanoscale engineering of materials we can really make a difference in how we make fuels and consume energy."Source: Stanford University (http://news.stanford.edu/news/2014/august/splitter-clean-fuel-082014.html)

Optical Microscope Technique Confirmed as Valid Nano-Measurement Tool

National Nanomanufacturing Network - August 27, 2014 - 4:20am
Recent experiments have confirmed* that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3-D) shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (about 250 nanometers for green light). The results could make the technique a useful quality control tool in the manufacture of nanoscale devices such as next-generation microchips. NIST’s experiments show that Through-focus Scanning Optical Microscopy (TSOM) is able to detect tiny differences in 3-D shapes, revealing variations of less than 1 nanometer in size among objects less than 50 nm across. Last year,** simulation studies at NIST indicated that TSOM should, in theory, be able to make such distinctions, and now the new measurements confirm it in practice. “Up until this point, we had simulations that encouraged us to believe that TSOM could allow us to measure the 3-D shape of structures that are part of many modern computer chips, for example,” says NIST’s Ravi Attota, who played a major role in TSOM’s development. “Now, we have proof. The findings should be helpful to anyone involved in manufacturing devices at the nanoscale.” Attota and his co-author, Ron Dixson, first measured the size of a number of nanoscale objects using atomic force microscopy (AFM), which can determine size at the nanoscale to high accuracy. However, the great expense and relatively slow speed of AFM means that it is not a cost-effective option for checking the size of large numbers of objects, as is necessary for industrial quality control. TSOM, which uses optical microscopes, is far less restrictive—and allowed the scientists to make the sort of size distinctions a manufacturer would need to make to ensure nanoscale components are constructed properly. Attota adds that TSOM can be used for 3-D shape analysis without needing complex optical simulations, making the process simple and usable even for low-cost nanomanufacturing applications. “Removing the need for these simulations is another way TSOM could reduce manufacturing costs,” he says. More details on the TSOM technique and its application to 3-D electronics manufacturing can be found in this story (http://www.nist.gov/public_affairs/tech-beat/tb20130625.cfm#tsom), which covers the 2013 simulation study. *R.
