  • Controlled height carbon nanotube arrays
    Patent number: 11708270
    Abstract: Controlled height carbon nanotube arrays including catalysts and synthesis methods relating thereto are disclosed. Such nanotube arrays can be prepared from catalyst particles having an Fe:Co:Ni molar ratio impregnated in an exfoliated layered mineral to grow carbon nanotube arrays where the Fe:Co:Ni molar ratio of the catalyst is used to control the height of the array.
    Type: Grant
