The crystal configuration of composites was analyzed by PXRD analysis using Rigaku MiniFlex X-ray diffractometer with Cu K _1 radiation ( λ = 0.15406 nm). The surface area was measured by nitrogen adsorption analysis at 77 K using an ASAP 2010, Micromeritics, USA surface area analyzer. FT-IR spectroscopic anal-ysis of the composites was performed on a Perkin Elmer FT 1730 spectrophotometer. UV–vis-DRS were recorded over the wave-length range of 200–800 nm using a Shimadzu UV-3101 PC UV–vis spectrophotometer. The UV–vis-DRS were utilized for estimating the band-gap values of synthesized MWCNT/TNT composite samples using mathematical methods from Kubelka-Munk model as reported elsewhere [31] and the values were tabulated in Table 2. XPS analysis of the composite samples was carried out using a ULVAC-PHI Quantera SXMTM scanning XPS microscope with Al- K _ as an X-ray source. The tubular morphology of MWCNT, TNT, and MWCNT/TNT composites was observed by SEM (Leo Series VP1430) and TEM (JEOL JEM-2010 electron microscope). The percentage loading of MWCNT was analyzed by CHNS analysis. The photo luminescence spectra of the photo catalysts were recorded on an Action research (Spectra Pro 215i) photo luminescence spectrophotometer at an excitation wavelength of 320 nm.
