Hexavalent chromium Cr(VI) is a highly toxic groundwater contaminant. In this study, we demonstrate selective electrochemical process tailored for removal of using hybrid MOF@rGO nanomaterial synthesized by in situ growth nanocrystalline, mixed ligand octahedral metal–organic framework with cobalt metal centers, [Co2(btec)(bipy)(DMF)2]n (Co-MOF), on the surface reduced graphene oxide (rGO). The rGO provides electric conductivity necessary an electrode, while Co-MOF endows adsorption sites...
Formation of mineral scale on a material surface has profound impact wide range natural processes as well industrial applications. However, how specific characteristics affect the mineral-surface interactions and subsequent formation is not understood. Here we report superior resistance hexagonal boron nitride (hBN) to compared only common metal polymer surfaces but also highly scaling-resistant graphene, making hBN possibly most scaling resistant reported date. Experimental simulation...
Abstract Mineral crystal formation poses a challenge on surfaces (e.g., heat exchangers, pipes, membranes, etc.) in contact with super-saturated fluids. Applying alternating currents (AC) to such can prevent surface crystallization under certain conditions. Here, we demonstrate that ion displacement induced by periodic charging and discharging of the electrical double layer (EDL) inhibits both heterogeneous homogeneous nucleation (and growth) CaCO 3 . Titanium sheets (meant simulate metallic...
Scale formation is an important challenge in water and wastewater treatment systems. However, due to the complex nature of membrane surfaces, effects specific surface characteristics on scale are poorly understood. In this study, independent effect hydrophobicity gypsum (CaSO4·2H2O) via surface-induced nucleation bulk homogeneous was investigated using quartz crystal microbalance with dissipation (QCM-D) self-assembled monolayers (SAMs) terminated -OH, -CH3, -CF3 functional groups. Results...
Electrocatalytic reduction to convert nitrate (NO3–) N2 or NH3 is of great interest for water and wastewater treatment, as well N cycle management. However, the inherent electrostatic repulsion between negatively charged ion cathode hinders adsorption on catalyst decreases reaction kinetics. In this study, we demonstrate that a simple polarity modulation strategy greatly enhances NO3– catalyzed by an iron nanocatalyst immobilized carbon black electrode (Fe@CB). By switching positive negative...
Halide perovskite nanocrystals (HPNCs) have emerged as promising materials for various light harvesting applications due to their exceptional optical and electronic properties. However, inherent instability in water biological fluids has limited use photocatalysts the aqueous phase. In this study, we present highly water-stable SiO2-coated HPNCs efficient antimicrobial applications. The double SiO2 layer coating method confers long-term structural stability water, while situ synthesis of...
One antibacterial material was prepared from exfoliated graphite (EG) decorated with silver nanoparticles (AgNPs). The EG by the intercalated compound process, AgNPs were chemical reduction of AgNO3 in presence NaBH4. AgNPs-loaded (Ag-EG) composite characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), nitrogen adsorption, mercury intrusion porosimetry, scanning electron microscopy (SEM), and transmission (TEM). effect Ag-EG evaluated using zone inhibition...
