A novel photocatalytically active mesoporous metal-free PPy grafted MWCNT nanocomposite.

A new mesoporous metal-free functionalized multi-walled carbon nanotube (f-MWCNT) covalently grafted polypyrrole (PPy) nanocomposite has been synthesized via chemical oxidative polymerization method keeping different weight ratio of f-MWCNT (1-4). Various instrumentation techniques such as UV-DRS, FT-IR, XRD, Raman, TGA, BET and TEM were used to characterize the as-prepared nanocomposite. The successfully constructed photocatalytically active mesoporous metal-free PPy grafted MWCNT nanocomposite was employed for the decontamination of nitrobenzene (NB).

Efficacious separation of electron-hole pairs in CeO-AlO nanoparticles embedded GO heterojunction for robust visible-light driven dye degradation.

Herein, we have developed a facile and one pot synthesis of ternary CeO-AlO@GO nanocomposite via wet chemical method. The structural and morphological characteristics of the synthesized nanocomposite was investigated using UV-DRS, FT-IR, XRD, FE-SEM, HR-TEM, EDX and TGA analysis. The CeO-AlO@GO composite was tested for its ability to photocatalytically degrade Rhodamine B (RhB) under visible light illumination.
