Effects of nitrogen doping on the structure of carbon nanotubes (CNTs) and activity of Ru/CNTs in ammonia decomposition

Nitrogen-doped carbon nanomaterials: To the mechanism of growth, electrical conductivity and application in catalysis

“…A decrease in the size of deposited metallic particles and their more uniform distribution in the case of nitrogen-doped carbon materials were demonstrated in [105][106][107][108][109][110][111]. A comparison of the 10%Pd/CNTs and 10%Pd/N-CNTs (0-5 at.% N) catalysts in hydrogenation of cinnamaldehyde with respect to activity and selectivity of C C bond hydrogenation demonstrated an evident advantage of N-CNTs [105].…”

Nitrogen-doped carbon nanotubes as a metal catalyst support

“…The challenge related to the use of the above supports is that they are not easy to remove from the products at the end of the reaction due to their high degree of insolubility. To overcome this challenge, carbon has been used as a support (Chen et al 2004(Chen et al , 2010aGao et al 2006;Garcia et al 2006;Guczi et al 2006;Reddy et al 2006;Chen et al 2007;Antolini 2009). Carbon can, in principle, be removed by oxidation.…”

Process Optimisation of In Situ H2 Generation From Ammonia Using Ni on Alumina Coated Cordierite Monoliths

“…It has been reported that ruthenium exhibits the highest TOF in ammonia decomposition [11]. Therefore, intensive research has been centered in ruthenium on different supports, such as alumina [12][13][14], activated carbon [15,16] or carbon nanotubes, with or without nitrogen doping [17][18][19][20]. However, ruthenium is a noble metal and, therefore, its high cost hinders its use in widespread applications.…”
