N-doped mesoporous carbons decorated with Pt nanoparticles in hydrotreatment reactions

摘要

New carbon materials,such as doped carbons have been studied in the last years with the focus in the development of different applications,such as electrochemical devices,CO2 and H2 sorbents,sensors or catalysts.The insertion a doping atom in the carbon matrix modifies chemical and electronic properties,giving an improved performance.It is also well know that materials with a specific morphology can be prepared using a template strategy.By combining these two approaches,it is possible to obtain tailored porous and doped carbons.The objective of this work is to prepare N-doped templated mesoporous carbons and use them as support of Pt nanoparticles to study the influence of N-doping in the activity of the catalysts.The aqueous phase hydrodechlorination(HDC)of 4-chlorophenol(4-CPh)was used as a test reaction to study the influence of N-doping in the catalytic activity.
