Langmuir-Derived Model for Diffusion- and Reaction-Limited Adsorption of Organic Compounds on Fractal Aggregates

open access: yes, 2016
Natural colloids, aerosols, and aggregates generated in wastewater treatments have fractal geometries, and so not all the surface sites of these aggregates possess the same collision probability.

Ion‐Enriched Porous Organic Polymer for Gold Recovery From E‐Waste

open access: yesEcoEnergy, EarlyView.
A novel ion‐enriched porous organic polymer was designed and synthesized. It exhibits ultrahigh gold adsorption efficiency with capacity up to 1530.9 mg g−1, and also shows selective capture ability towards gold ions in the actual CPU leaching solution, demonstrating its promising potential for gold recovery from actual e‐waste.

Discussion on the Gaseous Slip Model Based on Langmuir Adsorption Isotherm

open access: yes, 2012
Different from the Maxwell slip model, the gaseous slip model based on the Langmuir adsorption isotherm, i.e. the Langmuir slip model, takes into account the interfacial interaction between the gas molecules and the wall surface.

Bimetallic Synergy in Cocatalyst Alloy Nanoparticles for Efficient Photocatalytic Hydrogen Production

open access: yesEcoEnergy, EarlyView.
A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of

Adsorption isotherms in the approximation of Langmuir monolayer correlations

open access: yes, 2020
The influence of the lateral interactions and lattice monolayer cluster structure on both the adsorption kinetics and adsorption isotherms is discussed. The adsorption isotherms were theoretically calculated within the Langmuir approximation of the correlation sums at different lateral interaction energies.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.
