In the present work, facile preparation of MXenes based nanocomposite (MXene-CNTs) through catalytic chemical vapor deposition (cCVD) was demonstrated. The novel design of two and one-dimensional (2D/1D) MXene-CNTs composites for an extraordinary photocatalytic process for removal of Rhodamine B (RhB) using efficient photocatalytic dye degradations was compared to the performance of pure MXene. The surface morphological behavior of MAX, MXene and MXene-CNTs rational design of surface microstructure CNTs anchored on 2D materials MXene nanosheets product was characterized employing scanning electron microscopy (SEM). As-prepared direct growth CNTs by employing CVD method were in the size ranges of 40-90 nm as revealed from SEM images. The crystallographic structures of etching and delaminations of MAX and MXene-CNTs were observed for CNTs diffracted peaks at 2θ = 25.11° in support of (002) plan. The major C-O and (CC) stretching were confirmed. Prepared MXene and MXene-CNTs samples photocatalytic performance was investigated through photocatalytic Rhodamine B (RhB) dye degradation. MXene-based CNTs hybrid nanocomposites photocatalysts activity were estimated. The as-prepared pure MXene-RhB and MXene-CNTs-RhB materials calculated efficiency were 60 % and 75 %, respectively. The CVD preparations of new MXene-CNTs synthesis yield high and explored good successive cycles for hazardous pollutants.
