Optimization and predictive modelling of biodiesel production from waste cooking oil catalyzed by blast furnace slag geopolymer using RSM and machine learning

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Biodiesel production from waste cooking oil (WCO) has emerged owing to growing interest in sustainable energy sources. Geopolymers synthesized from industrial wastes, such as blast furnace slag (BFS), are promising catalysts because of their environmental benefits and catalytic properties.

Recycling Spent Synthesis Liquor for Enhanced Production of ZIF‐67: Characterization and Morphological Insights

open access: yesChemNanoMat, EarlyView.
Zeolitic imidazolate framework‐67 (ZIF‐67) is synthesized by recycling spent synthesis liquor that contains unreacted 2‐methylimidazole. This recycling process improves the yield of ZIF‐67 while preserving the dodecahedral rhombic shape of the particles. As the liquor is recycled, both the particle size and surface area increase. This study reports the

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

open access: yesChemPhysChem, 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.

Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

open access: yesChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic
