講座介紹:
Ball-milling is the most
frequently-used process in grinding, mixing, and organic synthesis, in which
high-speed metal balls deliver enough kinetic energy to cause mechanical
breakage, activating the surface of materials. Here, we show that ball milling hold
promise for realizing reactions that cannot occur under conventional
conditions, and being used in new fields. We have successfully achieved direct
nitrogen fixation using nitrogen as the nitrogen source under low temperature
and low pressure; and directly prepared single-atom catalysts by grinding large
pieces of metal.
