Mimicking The Photosynthetic Special Pair With Aluminum(III) Porphyrin Homodimer – Fullerene (C60) Supramolecular Assemblies Capable of Long‐Lived Charge Separation

open access: yesChemistry – A European Journal, EarlyView.
The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

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

open access: yesThe 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

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Recent Advances in Photocatalytic Urea Synthesis via C−N Coupling From C/N‐Containing Species: A Mini Review

open access: yesEcoEnergy, EarlyView.
This review systematically compares photocatalytic urea synthesis from various C (CO2, CO, CH3OH) and N (N2, NH3, NO3−) sources. It highlights C–N coupling mechanisms, key challenges, and future directions, offering a framework to guide rational catalyst design for sustainable, solar‐driven urea production.
