Adsorption of phenol from aqueous solutions on original and oxidized multiwalled carbon nanotubes

Adsorption Science & Technology, 2017
The surface heterogeneity of the multiwalled carbon nanotubes is investigated on the basis of adsorption isotherms from dilute aqueous phenol solutions at various temperatures. The Dubinin–Astakhov isotherm connected with the non-symmetrical distribution

Preserving Hierarchical Integrity During Primary Structure Modification of Spherulitic MOFs

Small, EarlyView.
A MOF‐74‐type zinc framework self‐organizes into well‐defined spherulitic superstructures while allowing precise covalent post‐synthetic modification (PSM) of the linkers. A built‐in tetrazine enables fast inverse electron‐demand Diels–Alder (iEDDA) functionalization to uniformly install primary amines.

Interface Modulation of rGO/Bi0/BiOCl Enables Efficient Electron Utilization for CO2 Photoreduction

Small, EarlyView.
A one‐step strategy constructs a coupled rGO/Bi0/BiOCl interface that shifts electron behavior from trapping to dynamic utilization, enabling improved CO2 photoreduction toward hydrocarbon products with enhanced selectivity (92%) toward CH4 and C2H4 and exhibits a 12‐fold increase in CH4 photoreduction activity compared to pristine water made BiOCl ...
