A simple, step-by-step approach for the preparation of MoO3@g-C3N4 nanocomposite

Abstract

Abstract We present a simple step-by-step method for the preparation of MoO3@g-C3N4 nanocomposite. Several approaches were used to prepare and characterize the nanocomposite with a weight ratio of MoO3 (0.075). X-ray diffraction measurements have revealed The primary peaks of MoO3 at 13.14°, 23.74°, 26.07°, 27.71°, 29.98°, and 39.33° correspond to the iq (020), (110), (040), (120), (021), and (060) planes, and the g-C3N4 appearing at 27.49° and 12.94° corresponds to the (002) and (100) planes in the MoO3@g-C3N4 nanocomposite. The specific bands for the as-prepared nanocomposite were revealed by Fourier-transform infrared. With the H3 hysteresis loops, the BET isotherm and the BJH technique produced results compatible with Type IV. Furthermore, the results indicated the effective change in surface area, pore-volume, and pore diameter values were larger in the MoO3@g-C3N4 nanocomposite. Diffuse spectroscopy of reflection data revealed more information about the changes that occurred when MoO3 was loaded on the g-C3N4 layers to shift the spectrum to the red extent while decreasing the band gap to 2.63 eV. Furthermore, field emission electron spectroscopy has proven the synthesis of nanocomposite by a dramatic change in the morphological surface as well as a change in the composition of elements that have been demonstrated using the energy-dispersive X-ray spectroscopy methodology. This discovery has improved the form and structure of the MoO3@g-C3N4 nanocomposite
