AbstractSince Ajayan and Ijima first reported introducing transition metals into carbon nanotube (CNT) channels,1 the well defined one dimensional nanochannel structure has attracted great attention because the incorporation of guest materials could create novel nanomaterials for wide applications.2 Recently, there is increasing interest for catalysis applications. First of all, the space restriction of the channels provides a possibility to tune particle size and to alleviate the sintering problem for nanoparticles. Secondly, reduction of transition metal oxides can be facilitated when they are confined in CNTs, which can benefit certain reactions. Thirdly, a unique metal-support interaction may result in because of the deformed sp2 hybridization electron structure of the curved graphene walls. Fourthly, inside such small channels the interactions of gas molecules with the pore walls may become increasingly important and could dominate with respect to the intermolecular interaction. Several reactions are shown to exhibit different performance from metal particles supported on CNT outer walls due to confinement effects inside CNT channels for example (selective) hydrogenation,3 Fischer-Tropsch synthesis,4 NH3 synthesis and NH3 decomposition.5 1.
