Carbon nanoreactor catalysts represent an exciting opportunity for the development of low cost, sustainable and high through put catalysts.\u00a0 The unique properties of these materials, both in terms of shape and behaviour, drastically effect the chemical reactions which they catalyse.\u00a0 Fe, Ni and Ru catalysts along with copper chromite bimetallic catalysts have been fabricated and microscopy reveals small particles of the specific metal\/metals embedded in the carbon support in each case.\u00a0 The shape of the catalyst and the crucial role it plays in controlling on the outcome of reactions was investigated using simple and competitive hydrogenation reactions. In addition the materials were immobilised in a tube reactor allowing reagents to be flowed through the catalyst and optimal reaction conditions to be determined.\u00a0 Our study represents the essential fundamental method development required to combine the enhanced stability and activity exhibited by metal nanoparticle\u2011carbon nanotube catalysts with the high process efficiency of flow reactors.\u00a0 A crucial step if these materials are to find application in high through put industrial processes such as the conversion of biomass-derived feedstocks into high-value chemicals.<\/p>\n
