Аннотация

Углеродная эрозия массивных металлов и сплавов в углеродсодержащей атмосфере может служить эффективным инструментом для направленного синтеза углеродных наноматериалов. В представленной работе синтезирована серия массивных сплавов Ni0.89Cu0.11 (11 ат. % меди) методом механохимического сплавления металлических порошков в планетарной мельнице “Активатор 2S”. Полученные образцы исследованы в качестве предшественников катализатора для синтеза углеродных нановолокон (УНВ) при 550°С из этилена. Изучено влияние времени активации на морфологию частиц и фазовый состав сплавов, а также кинетику роста и выход углеродного продукта в разложении C2H4. Для наиболее активных образцов выход УНВ превысил 100 г/гкат за 30 мин реакции. С применением методов микроскопии исследован ранний этап процесса углеродной эрозии массивного сплава Ni0.89Cu0.11. Установлено, что зарождение активных центров роста углеродных нитей происходит в течение краткого контакта образца с реакционной смесью (менее 1 мин), а полная дезинтеграция сплава наблюдается через несколько минут. Углеродный продукт представлен нановолокнами субмикронного диаметра с плотной “стопчатой” и коаксиально-конической упаковкой графеновых слоев. Материал характеризуется развитой удельной поверхностью (140–170 м2/г) и легким насыпным весом (менее 30 г/л).

title = "Carbon Erosion of a Bulk Nickel–Copper Alloy as an Effective Tool to Synthesize Carbon Nanofibers from Hydrocarbons",

abstract = "Carbon erosion of bulk metals and alloys in a carbon-containing atmosphere can be used as an effective tool for the targeted synthesis of carbon nanomaterials. In this study, a set of bulk Ni0.89Cu0.11 (11 at % Cu) alloys has been synthesized by the mechanochemical alloying of metal powders in an Activator 2S planetary mill. The synthesized samples have been studied as precursors of catalyst for the synthesis of carbon nanofibers (CNFs) from ethylene at 550°C. The effect of the activation time on the particle morphology and phase composition of the alloys, the kinetics of growth, and the carbon product yield in C2H4 decomposition has been studied. For the most active samples, the CNF yield has exceeded 100 g/gcat within 30 min of reaction. The early stage of carbon erosion of a bulk Ni0.89Cu0.11 alloy has been studied by electron microscopy methods. It has been found that the nucleation of carbon fiber growth active sites occurs during a short-term contact of the sample with the reaction mixture (less than 1 min); the complete disintegration of the alloy is observed in a few minutes. The carbon product is represented by nanofibers having a submicrometer diameter and characterized by a dense “stacked” and coaxial-conical packing of graphene layers. The material has a developed specific surface area (140–170 m2/g) and a low bulk density (less than 30 g/L).",
