“…In fact, the presence of heteroatoms, i.e., phosphorus, and the carbonyl/carboxyl surface groups on carbon nanoparticles, was proposed to confer peculiar properties allowing the fast Mn(VII) reduction to Mn(II) at neutral pH and the Cr(VI) reduction to Cr(III) in weak acid aqueous media.…”

“…Analytical techniques, that is, high-resolution transmission electron microscopy, scanning electron microscopy, electron dispersive X-ray analysis, selected area electron diffraction, and X-ray photoelectron spectroscopy, showed that unlike nanoballs and particles composed of crystalline germanium, the layer was made of chromium germanide CrGe(x). The nanowires possessed a complex structure, namely a thin crystalline germanium core and amorphous CrGe(x) coating. …”

“…As a result, the dual-modified biochar with KMnO(4) and AlCl(3)·6H(2)O has the calculated adsorption energy of −0.52 eV and −1.64 eV for HCrO(4)(−), and −0.21 eV and −2.01 eV for Cr(2)O(7)(2−). The Al(2)O(3) (aluminum oxide) and MnO (manganese oxide) embedded on the surface of dual-modified biochar bring more Cr(VI) absorption sites comparing to single-modified biochar, resulting in a maximum Cr(VI) saturated adsorption capacity of 152.86 mg g(−)(1). …”
