Towards Halogen Bonding MOFs: Networking With a Polyiodinated and Perfluorinated Terphenyl Ligand and Divalent Zinc

open access: yesChemistry – A European Journal, EarlyView.
One ligand, three new architectures with different intermolecular interactions: a polyhalogenated terphenyl linker with carboxyl groups coordinates Zn2+ to form (i) a metal‐containing hydrogen‐bonded organic framework; (ii) a metal‐organic framework or (iii) one‐dimensional metal‐organic chains with intermolecular halogen bonding and hydrogen bonding ...

Experimental Investigation on the Effect of Dry and Wet Activation Processes on the Morphological Properties of Activated Carbon Derived From Sugarcane Bagasse

open access: yesCarbon Innovation, EarlyView.
Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

open access: yesChemie Ingenieur Technik, EarlyView.
Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°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
