Lawrence Berkeley Lab develops map of possible stable ternary nitride compounds
June 19, 2019

Lawrence Berkeley Lab, Calif., in close collaboration with the National Renewable Energy Laboratory and other institutions, has developed a large interactive stability map of the ternary nitrides, highlighting nitride compositions. Stable phases are indicated on the ternary phase diagram shown by a blue square. So far, the map has yielded the prediction of 244 new stable ternary nitride compounds.
Formed by elements combining with nitrogen, nitrides can possess unique properties with potential applications from semiconductors to industrial coatings. But before nitrides can be put to use, they first must be discovered – and the odds of finding them in nature are slim.
“For ancient explorers, sailing into the unknown was a very risky endeavor, and in the same way, exploration of new chemical spaces can also be risky,†explained Wenhao Sun, lead author of the paper and staff scientist at Berkeley Lab. “If you don’t find a new material where you are looking, it can be a big waste of time and effort. Our chemical map can help to guide the exploratory synthesis of nitrides, just as maps helped to guide explorers, allowing them to navigate better.â€

Mineral and organic acids extract rare earth elements from phosphate rock waste
March 11, 2019
Source:
Researchers from Rutgers University-New Brunswick, N.J., and members of the Critical Materials Institute in Ames, Iowa, announce that they have found a possible new source of rare earth elements in phosphate rock waste, and have developed an environmentally friendly way to extract the elements. Results of their study were published in the Journal of Chemical Thermodynamics.
The research team explored using mineral and organic acids, including a bio-acid mixture, to extract six rare earth elements (yttrium, cerium, neodymium, samarium, europium, and ytterbium) from synthetic phosphogypsum. Scientists led by David Reed at Idaho National Laboratory produced the bio-acid mixture - consisting primarily of gluconic acid, found naturally in fruits and honey - by growing the bacteria Gluconobacter oxydans on glucose.
The results suggest that the bio-acid did a better job extracting rare earth elements than pure gluconic acid at the same pH (2.1), or degree of acidity. The mineral acids (sulfuric and phosphoric) failed to extract any rare earth elements in that scenario. When the four acids were tested at the same concentration, only sulfuric acid was more effective than the bio-acid.
Each year, an estimated 250 million tons of phosphate rock are mined to produce phosphoric acid for fertilizers. In the United States, approximately 28 million metric tons were mined in 2017. Rare earth elements generally amount to less than 0.1 percent in phosphate rock. But worldwide, about 100,000 tons of these elements per year end up in phosphogypsum waste. That's almost as much as the approximately 126,000 tons of rare earth oxides produced worldwide each year.

Australian scientists develop molten metal catalyst to change carbon dioxide into coal
March 3, 2019

RMIT University in Melbourne, Australia, announces that its researchers have developed a molten metal catalyst technique that can efficiently convert carbon dioxide from a gas into solid particles of carbon. Published in the journal Nature Communications, the research offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere.
RMIT researcher Dr. Torben Daeneke, an Australian Research Council DECRA Fellow, says that converting CO2 into a solid could be a more sustainable approach. “While we can’t literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock,†says Dr. Daeneke “By using liquid metals as a catalyst, we’ve shown it is possible to turn the gas back into carbon at room temperature, in a process that’s efficient and scalable. While more research needs to be done, it’s a crucial first step to delivering storage of solid carbon.â€
Lead author Dr. Dorna Esrafilzadeh, a Vice-Chancellor’s Research Fellow in RMIT’s School of Engineering, developed the electrochemical technique. The researchers designed a liquid metal catalyst with specific surface properties that made it extremely efficient at conducting electricity, while chemically activating the surface. The carbon dioxide is dissolved in a beaker filled with a liquid electrolyte and a small amount of the liquid metal, which is then charged with an electrical current. The CO2 slowly converts into solid flakes of carbon, which are naturally detached from the liquid metal surface, allowing the continuous production of carbonaceous solid.
Dr. Esrafilzadeh says the carbon produced could also be used as an electrode. “A side benefit of the process is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles. The process also produces synthetic fuel as a by-product, which could also have industrial applications.â€
The paper is published in Nature Communications (“Room temperature CO2 reduction to solid carbon species on liquid metals featuring atomically thin ceria interfacesâ€, DOI: 10.1038/s41467-019-08824-8).

U.S. Department of Energy grant to advance electrolysis process for copper production.
October 4, 2018
Source:
The Massachusetts Institute of Technology, Cambridge, announces that associate professor of metallurgy Antoine Allanore has received a $1.9 million grant from the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy to run larger scale tests of a new way to produce copper using electricity to separate copper from melted sulfur-based minerals, which are the main source of copper.
In June 2017, researchers in Prof. Allanore’s lab identified how to selectively separate pure copper and other metallic elements from sulfide mineral ore in one step. Their molten sulfide electrolysis process eliminates sulfur dioxide, a noxious byproduct of traditional copper extraction methods, instead producing pure elemental sulfur.
“We think that with our technology we could provide these copper wires with less energy consumption and higher productivity,†Prof. Allanore says. It may be possible to cut the energy needed for making copper by 20 percent.
In earlier research, postdoc Sulata K. Sahu and graduate student Brian J. Chmielowiec decomposed sulfur-rich minerals at high temperature into pure sulfur and extracted three different metals at very high purity: copper, molybdenum, and rhenium. The process is similar to the Hall-Héroult process, which uses electrolysis to produce aluminum, but operates at a higher operating temperature to enable production of liquid copper.
Currently, it takes multiple steps to separate out copper, first crushing sulfide minerals, and then floating out the copper-bearing parts. This copper-rich material — copper concentrate — is next partially refined in a smelter, and further purified with electrolytic refining.
“Professor Allanore’s approach would work on the copper concentrate and has the potential to produce copper rod in a single operation while separating unwanted impurities and recovering valuable byproducts that are also in the concentrate,†says Hal Stillman, director of technology development and transfer for the International Copper Association. “Professor Allanore’s approach is a big step; it allows a completely new approach to refining copper.â€
The three-year, $1.89 million DOE award will allow Allanore’s group to make a larger reactor, producing about 10 times as much liquid copper per hour, and to run the reactor for a longer time, enough to identify what happens to the other metals accompanying copper, which are also commercially important.
