“…Carbon nanotubes (CNTs) , have attracted interest because of their small diameter, large surface-to-volume ratio, great structural integrity, high electrical and thermal conductivity, good thermal and chemical stability, and exceptional strength and resilience. − Functionalization of CNTs with various chemical groups , and nanocrystals − can further enhance the properties of CNTs, and CNTs have been considered as superior supports for nanocrystal catalysts. , In fact, hybrid materials consisting of nanocrystals distributed on the surfaces of CNTs could potentially display not only the unique properties of nanocrystals , and those of nanotubes − but also additional novel properties. Recently, such CNTs with nanocrystals have been shown to be promising for various energy applications including solar cells, , fuel cells, , Li−ion batteries, and hydrogen storage. , …”
