Enhancing the Photocatalytic Activity via Direct CovalentFunctionalization in Single-Walled Carbon Nanotubes

[EN] Herein, the direct covalent functionalization of single-walled carbon nanotubes (SWNT) is presented with an amino-decorated phenyl-phenothiazine (PTH-NH2) organophotocatalyst through the diazonium chemistry protocol. Three different SWNT-PTH hybrids are prepared by varying the amount of PTH-NH2...

Three different SWNT-PTH hybrids are prepared by varying the amount of PTH-NH2 and diazonium agent and are fully characterized. These hybrids differ not only in the degree of functionalization, but also in the chemical structure and the photophysical properties. The study shows that these features affect the photoredox activity of the materials in the photo-debromination of aromatic halides. Thus, sample SWNT-PTH-5, a functionalized nanotube with a 5% wt loading of PTH, surpasses the catalytic performance of homogeneous PTH in 11 different substrates, finishing the reaction in shorter times, in a recyclable manner and without catalyst leaching. This study demonstrates the importance of controlling the functionalization degree of SWNT with photocatalysts to prepare photocatalytic materials with even higher catalytic activity than that presented by the homogeneous PTH catalyst.This work was supported by the MICINN (PID2021-122299NB-100, TED2021-129999B-C32, and TED2021-130470B-100), VIRMAT Projects in response to COVID-19 financed by the ERDF-REACT-EU resources, Comunidad de Madrid for European Structural Funds (S2018/NMT4367) and proyectos sinérgicos I+D (Y2020/NMT-6469).
