Abstract null null Herein, we report the electrochemical energy storage performance of δ-MnO2 (K-birnessite MnO2) as supercapacitor electrode material in Na2SO4 aqueous electrolyte. The electrode exhibited considerable electrochemical performances due to the fast intercalation/deintercalation reactions of Na+ on the pseudocapacitive MnO2 surface. However, a long-term cyclic stability test of the electrode at a low specific current (1 A g-1) demonstrated a decline in its initial capacitance value...

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 Graphene synthesized via electrochemical exfoliation of graphite is considered to be a simple, fast, and scalable technique. This exfoliation technique leads to the formation of multi-layer graphene sheets with some defects, which is feasible for developing supercapacitor electrodes due to the presence of various pseudocapacitive functionalities. We report the exfoliation of multi-layer graphene via pulse sonication assisted electrochemical exfoliation technique (sonoelectroch...

Abstract null null Electrochemical water splitting has considered as an attractive technique in generating clean hydrogen fuel as secondary energy storage. For large-scale production of hydrogen, electrolysis of seawater is considered to the replacement for fresh water due to its natural abundance. However, the alternation requires the development of a robust and cheap electrocatalyst that can perform seawater splitting without undergoing any chloride corrosion at the anode surface. Herein we fa...

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...

Abstract Cationic π-conjugated polyelectrolytes (CPEs) were successfully intercalated into layered titanate (TiO 2 ), while exfoliated layered titanates were reassembled into lamellar structures. The resulting composites showed significantly enhanced visible light absorbance and enhanced photocatalytic activity with respect to layered titanate, which was proven by the photodegradation of methylene blue in aqueous media under irradiation by visible light. Notably, some amount of tetrabutylammoniu...
