Abstract null null The flue gas desulfurization wastewater (FGDW) contains extremely high concentration of heavy ions (e.g., Ca2+, Mg2+) and unbiodegradable organic pollutants such as humic substances. In this paper, the effects of softening pre-treatment on water reclamation performance and membrane fouling phenomenon of the direct contact membrane distillation of FGDW were investigated systematically. Results showed that fouling on the membrane caused by crystallization of CaSO4, Mg-Si complex...

Abstract null null In this study, we fabricated a novel hybrid photocatalyst (CD-BVO/rGH) by coupling carbon dot (CD)-decorated BiVO4 (BVO) with a reduced graphene hydrogel (rGH). The CD-BVO/rGH photocatalyst significantly enhanced the photocatalytic efficiency for tetracycline hydrochloride (TCH) degradation compared with pure BVO and BVO/rGH under simulated solar irradiation. CD-BVO/rGH also showed a substantial performance in the photocatalytic reduction of CO2. The enhanced photocatalytic ac...

Abstract null null Carbon-based materials have attracted extensive interest in metal-ion batteries owing to their low cost, good conductivity, and environmental friendliness. The practical application of graphite materials is associated with trade-offs in cyclability and energy density due to the sluggish kinetics. Herein, nitrogen-doped chain-like carbon nanospheres (NCN) with expanded interlayer distance are effectively fabricated by annealing carbon derived from aniline combustion. More impre...

Abstract The efficient removal of antibiotics in water is essential to protect aquatic environment as antibiotics are some of the most hazardous pollutants in water. Herein, we report the synthesis of a novel N-GNDs/Ag/BiVO4 ternary photocatalyst consisting of BiVO4 coupled with Ag nanoparticles (Ag-NPs) and nitrogen-doped graphene nanodots (N-GNDs) to degrade and mineralize tetracycline hydrochloride (TC•HCl) in water. The ternary photocatalyst shows higher photocatalytic degradation of TC•HCl ...

Abstract Membrane wetting and fouling represent the foremost concerning issues confining membrane distillation in the treatment of industrial wastewater. This work presents a superhydrophobic poly(vinylidene fluoride) (PVDF) membrane with anti-fouling property, which was derived from the bioinspired adhesive, mineralization and fluorination process for the direct contact membrane distillation (DCMD). The synthesis of membrane was initiated by co-depositing polydopamine/polyethylenimine composite...

ABSTRACT In this study, we report the construction of a novel composite photocatalyst (BiVO4/rGH) composed of quantum dots (QDs) self-decorated BiVO4-nanoparticels (NPs) and reduced graphene hydrogel (rGH). The composite structures were prepared using an in-situ growth method. The BiVO4/rGH composite photocatalysts exhibited excellent photocatalytic efficiency for the degradation of tetracycline hydrochloride (TC HCl). The promoted photocatalytic activity of the BiVO4/rGH is attributed to the sy...

Abstract The Z-scheme BiVO4/α-Fe2O3 photocatalyst was synthesized by a simple hydrothermal method. The photocatalyst is composed of α-Fe2O3 nanocubes with a regular cubic structure and the BiVO4 particles distributed on the surface of the α-Fe2O3 nanocubes. The photocatalytic performance of Z-scheme BiVO4/α-Fe2O3 photocatalyst was investigated in terms of its capacity for photodegradation of tetracycline hydrochloride. Improved photocatalytic activity was observed for Z-scheme BiVO4/α-Fe2O3 phot...
