In this study, the adsorption of methyl red (MR) dye from wastewater on nickel oxide (NiO) doped in porous carbon derived Hyphaene thebaica (HT) seeds (NiO@HT C) as an adsorbent material was investigated.
We present here a new approach for the synthesis of nitrogen-doped porous graphitic carbon (g-NC) with stoichiometry C6.3H3.6N1.0O1.2, using layered silicate as hard sacrificial template. Autogenous exfoliation is achieved due to heterostacking 2D and layers. Micro- meso-porosity induced by melamine cetyltrimethylammonium (C16TMA). Our density functional calculations X-ray photoelectron spectroscopy (XPS) observations confirm that most dominant nitrogen configuration in g-CN graphitic, while...
In this study, the carbon sphere (Cs) has been prepared and modified by titania nanotubes (TNTs) to be utilized as an adsorbent toward crystal violet (CV) dye a model for cationic dyes from aqueous solution.
Herein, a feasible chemical reduction method followed by intensive mixing was applied for the preparation of an attractive material based on graphite studded with cuprous oxide nanoparticle-based cubes (Cu2ONPs–C@G). Transmission electron microscope (TEM), scanning (SEM), X-ray diffraction (XRD) and cyclic voltammetry (CV) were utilized characterization. Cuprous nanoparticles (Cu2ONPs), diameter range mainly distributed from 4 to 20 nm, aggregate form microcubes (Cu2ONPs–C) average about 367...
Metal–support interaction plays a critical role in determining the eventual catalytic activity of metals loaded on supporting substrates. This can sometimes cause significant drop metallic property metal and, hence, reactions, especially those for which low charge carrier transfer resistance is necessary parameter. Therefore, there should be case-by-case experimental or theoretical (or both) in-depth investigation to understand support each metal. Here, onto layered porous carbon nitride...
