Nonlinear Active Site Dynamic Behavior Over In Situ Generated Working Zeolites

Chemie Ingenieur Technik, EarlyView.
The methoxymethyl mechanism over α, β, and γ site ensembles and the dynamic site‐interconversion mechanism reduce the induction period of propylene formation. The methoxymethyl mechanism acts on site ensemble α generating surface methoxy species (SMS), which, through the dynamic site‐interconversion mechanism, lead to SMS on site ensembles β and γ that

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

The Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.
