Summary: Given the large amount of harmful pharmaceuticals being released into the water stream, it is crucial to eradicate or reduce these chemicals to a minimum permissible limit. This study reports the fabrication of a magnetic guar gum graphene oxide nano-composite (mGG/GO NC) for the adsorption of ciprofloxacin from wastewater. Various techniques were used to characterize the guar gum and the nanocomposite, and it was found that the adsorption process followed the pseudo second order model and Langmuir isotherm model. The nanocomposite exhibited high adsorption capacity and recyclability, potentially due to a synergistic effect of multiple interactions in the adsorption mechanism.

The technology can also convert nonbiodegradable effluent into a biodegradable form.

Summary: Copper ferrite nanoparticles loaded on montmorillonite (MMT-CuFe2O4) were applied as catalyst for the activation of peroxymonosulfate (PMS) in the degradation of reactive black 5 (RB5). The efficiency of RB5 removal depended on operating parameters, and the highest removal percentage was achieved using specific dosages and concentrations. Anions such as Cl-, NO3-, HCO3-, and SO42- had a limiting effect on RB5 degradation in the MMT-CuFe2O4/PMS system. Radical species such as ·OH and SO4 center dot- were involved in the catalytic degradation of RB5, with ·OH being the major species. The reusability of MMT-CuFe2O4 was tested and showed stability over multiple cycles. Toxicity tests using Daphnia magna demonstrated a significant decrease in toxicity after treatment. The degradation of RB5 and the production of specific ions confirmed the effective mineralization of pollutants. MMT-CuFe2O4 exhibited high catalytic performance and could be considered a promising catalyst for RB5 degradation from aqueous solutions.

Summary: This pilot study synthesized γ-Fe2O3@SiO2@ZIF8-Ag nanocomposites using the hydrothermal method as a novel photocatalyst for amoxicillin degradation in aqueous solutions under visible light radiation. The photocatalyst exhibited proper formation and complete degradation of amoxicillin was achieved under specific conditions. The degradation efficiency decreased with the presence of anions in the reaction medium and the dominant reactive species in amoxicillin photodegradation was determined. The synthesized photocatalyst showed promising potential for amoxicillin degradation due to its recyclability, activation by various light sources, and excellent mineralization.

Summary: In this study, a bimetallic Cu-Pd composition on 2D Ti3C2Tx (MXene) nanosheets is formulated to achieve more efficient formate production in CO2RR.

This simple strategy represents an important step towards the experimental demonstration of 3D-MXenes-based electrocatalysts for CO2RR application and opens up a new platform for the fabrication of macroscale aerogel MXene-based electrocatalysts.
