Controlling the size of nanoclusters: First step in making new catalysts to control pollution

摘要

Researchers from the U.S. Department of Energy's (DOE) BrookhavenNa-tional Laboratory and Stony Brook University have developed a new instrument that allows them to control the size of nanoclusters - groups of 10 to 100 atoms - with atomic precision. They created a model nanocatalyst of molybdenum sulfide, the first step in developing the next generation of materials to be used in hydrodesulfurization, a process that removes sulfur from natural gas and petroleum products to reduce pollution.
