Sorption Equilibrium Studies of Toxic Nitro-Substituted Phenols on Fly Ash

Adsorption Science & Technology, 2004
The potential of fly ash, a low cost and abundantly available material with good sorption properties, for removing phenols was investigated. Nitro-substituted phenols, i.e. o -nitrophenol, m -nitrophenol and p -nitrophenol, were selected for the studies.

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Carbon‐Modified SnS2/g‐C3N4 S‐Scheme Heterostructure with Enhanced Interfacial Charge Transfer for Efficient Photocatalytic Reduction of Cr(VI) and 4‐Nitrophenol

Small, EarlyView.
The S‐scheme of SnS2‐C/g‐C3N4 heterostructure enables Photocatalytic Cr(VI) and 4‐NP reduction. ABSTRACT Hexavalent chromium (Cr(VI)) and 4‐nitrophenol (4‐NP) are persistent and highly toxic water pollutants that require efficient treatment under mild conditions. In this work, L‐cysteine‐derived carbon‐modified SnS2 (SnS2‐C) was prepared hydrothermally

Investigations on the Luminescence Behavior of a Flavin Derivative Incorporated Into Al‐Based Metal–Organic Frameworks for the Sensing of Aromatic Nitro Compounds

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
For nitro group‐containing volatile compounds, a quenching effect was observed for DAMI@MOF, while the non‐nitro compounds chlorobenzene, toluene, and benzene yielded a fluorescence enhancement, rationalized by the relative energies of the derivative 8‐(dimethylamino)‐10‐methylisoalloxazine (DAMI) and analyte S1 states, with concomitant opposite ...
