With a recycling innovation for plastics, more may be produced with the same amount of precious metal ruthenium while also increasing conversion to valuable items. It will be presented at the American Chemical Society's autumn meeting in Chicago today, August 22, 2022. The very low metal load is the main finding, according to the research team's leader, chemist Janos Szanyi of the Pacific Northwest National Laboratory (PNNL). "This greatly reduces the cost of the catalyst." The new method, known as "upcycling," more effectively transforms plastics into valuable commodity chemicals. In addition, compared to other documented methods, it produces a lot less methane as a byproduct, a harmful greenhouse gas. Postdoctoral research scientist Linxiao Chen, who presented the study at ACS, said, "It was really interesting to us that there had been no published work revealing this outcome. This study demonstrates the possibility of creating efficient, picky, and a...

Chemical reactions can be accelerated by the presence of catalysts, which is crucial for industrial chemistry. Platinum, however, makes a great catalyst for several reactions, although it is rather expensive. In actuality, it is a precious metal with a higher value than gold. Because of this, developing new, less priced catalysts is tremendously beneficial. Researchers have combined liquid gallium and platinum in the same manner. Australian researchers have developed low-cost, highly effective chemical reactions using trace amounts of liquid platinum, paving the possibility for significant emissions reductions in key industries. The amounts of platinum needed, when combined with liquid gallium, are so small as to significantly increase the earth's platinum reserves, as well as possibly providing more sustainable solutions for CO2 reduction, ammonia synthesis in fertilizer production, and the development of green fuel cells, among many other potential uses in the chemical industries...

The exorbitant price of platinum has prevented the commercialization of eco-friendly gasoline for years, but a study suggests that a low-cost catalyst could be a workable replacement. Researchers have been searching for a catalyst that may drastically reduce the cost of manufacturing hydrogen fuel cells for many years. Such a discovery might usher in a green energy revolution, with computers and trains using fuel that simply yields water as a byproduct. Recent University at Buffalo studies suggest that the researchers may be coming closer to attaining this goal (UB). Efficiency, durability, and affordability have been designated as the three key objectives for fuel cell research by the United States Department of Energy (DOE). Scientists describe how iron may be mixed with nitrogen and carbon to create a catalyst that satisfies all three requirements in a research that was just published in Nature Energy.
