Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Hypervalent Iodine‐Mediated Synthesis of Sulfones Using Organozinc Pivalates and Sulfinate Salts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A general protocol for sulfone synthesis via sulfonyl‐containing hypervalent iodine reagents and organozinc pivalates is described. The method is practical, provides a broad scope of sulfone in moderate to high yield. bicyclo[1.1.1]pentane‐sulfones are also disclosed and a one‐pot synthesis of Diels–Alder adduct is presented. Sulfones are key motifs in

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,
