Chemically durable and effective absorbent materials for selenite (SeO32- ) remain highly desirable contamination remediation. Now a bismuth-based metal-organic framework (Bi-MOF, CAU-17) was used as adsorbent to capture SeO32- anions from aqueous solution with ultrahigh adsorption capacity of 255.3 mg g-1 fast kinetics. Furthermore, the showed excellent selectivity able work steadily in broad pH range 4-11. Density functional theory (DFT) calculation, XANES modeling, EXAFS fitting suggested...

Abstract The production of hydrogen peroxide (H 2 O ) through two‐electron oxygen reduction reaction (2e − ORR) has emerged as a more environmentally friendly alternative to the traditional anthraquinone method. Although oxidized carbon catalysts have intensive developed due their high selectivity and activity, yield conversion rate H under overpotential still limited. produced was rapidly consumed by increased intensity reduction, which could ascribe decomposition radicals voltage in...

The nanostructured metal sulfides have been reported as promising anode materials for sodium-ion batteries (SIBs) due to their high theoretical capacities but suffered from the unsatisfactory electronic conductivity and poor structural stability during a charge/discharge process, thus limiting applications. Herein, one-dimensional (1D) porous FeS/carbon fibers (FeS/CFs) micro/nanostructures are fabricated through facile pyrolysis of double-helix-structured Fe-carrageenan fibers. FeS...

The rational design and optimization of solid polymer electrolytes (SPEs) are critical for the application safety high efficiency lithium ion batteries (LIBs). Herein, we synthesized a novel poly(ethylene oxide) (PEO)-based SPE (PEO@AF SPE) with cross-linking network by introduction alginate fiber (AF) membranes. Depending on high-strength supporting AF skeleton formed hydrogen bonds between PEO matrix skeleton, obtained PEO@AF exhibits an excellent tensile strength 3.71 MPa, favorable heat...

The introduction of oxygenous functional groups onto graphene can provide additional pseudocapacitance for supercapacitors. However, how to balance the amount introduced and reduced electrical conductivity arising from disruption conjugated system remains a big challenge. Here, controllable strategy is reported prepare moderately oxidized oxide (MORGO) via an electrochemical oxidation process. MORGO not only has with appropriate quantities, but also preserves highly crystalline structure π-π...

We have witnessed the fast progress of cathodic photoelectrochemistry over past decades, though its signal transduction tactic still lacks diversity. Exploring new sensing strategies for is extremely demanding yet hugely challenging. This article puts forward a unique idea to incorporate an enzymatic reaction-invoked surface polarization effect (SPE) on BiOIO3 implement innovative photoelectrochemical (PEC) bioanalysis. Specifically, thioredoxin reductase (TrxR)-mediated reaction produced...
