The deposition of particles in pre-defined regions of a support material on the nanometer scale is still a challenge,while macroscopically this can be achieved, such as in the synthesis of egg-shell type catalysts.1Liquid ammonia has recently been considered as a potential source for clean and carbon oxide free hydrogen.2,3 Generating H2 via ammonia decomposition has gained much attention because of the low cost of this technology and ease of operation compared to the complex systems required for reforming of methanol or hydrocarbons.In order to not only control particle sizes, but also particle location in such materials, we developed a pathway for the targeted modification of only the intra-tubular pores of CMK-5 to create highly active catalysts for ammonia decomposition.
