Tunable H2/Syngas Production by Chemical Looping Reforming of Methane over La0.6Sr0.4MxM’1‐x(M,M’ = Fe, Mn, Co)O3 Perovskites

open access: yesChemCatChem, EarlyView.
B substitution in La0,6Sr0,4BxB'1‐xO3 perovskite materials for chemical looping reforming of methane is systematically studied by TPR/TPO experiments. Results suggest a positive effect of Mn on Fe‐based perovskites. Moreover, a novel 3‐step cycle leading to two syngas streams and one pure hydrogen stream is proposed and experimentally verified ...

Sustainable One‐Pot Synthesis of N‐Substituted Pyrroles Using a Multifunctional Cobalt‐Based Catalyst

open access: yesChemCatChem, EarlyView.
The one‐pot synthesis of N‐substituted pyrroles from nitrobenzene and 2,5‐hexanodione is first ever reported with >99% conversion and >99% chemoselectivity, in a green solvent, using a non‐noble metal‐based catalyst and hydrogen as a reductant under mild reaction conditions simultaneously.

Efficient Photocatalytic Degradation of Methylene Blue From Aqueous Solution Using Hybrid Biomass‐Derived Nanostructured Carbon‐TiO2 Photocatalyst

open access: yesChemistry – A European Journal, EarlyView.
A hybrid photocatalyst of biomass‐derived carbon nanospheres and TiO₂ has been developed from waste coffee leaves, achieving 99% MB dye degradation. The carbon reduces the bandgap, boosting UV photocatalysis, and the material shows excellent stability and recyclability, offering a sustainable, scalable solution for wastewater treatment.
