In this report, functionalized MCM-41 adsorbents (MCM-41/IL and MCM-41/NH2) were synthesized, and their performances were systematically compared in Cr(VI) removal. The adsorption capacities reached 110.2 mg/g for MCM-41/IL and 153.3 mg/g for MCM-41/NH2 at pH 5.6 with an adsorbent dosage of 1 g/L. Notably, functionalization led to a reduction in the surface area and pore volume, which significant…

Surface-active tertiary amines have recently emerged as promising solvents for CO2 capture by promoting bicarbonate formation in aqueous media. This paper presents the systematic evaluation of a new class of surface-active amines, N-xPO (x = 4, 6, 9, 12, and 15), under experimental conditions relevant to industrial scenarios, such as low-purity CO2 streams and high-concentration amine solutions. …

Olivine-type LiMnxFe1–xPO4 (LMFP) is a promising high-voltage cathode for next-generation lithium-ion batteries; however, its commercialization is hindered by structural instability from Mn3+ Jahn–Teller distortion and sluggish ionic kinetics. Herein, we develop a novel gradient-insertion strategy to address these limitations simultaneously. Through a facile solid-state process, Mg2+ is incorpora…

This study aims to elucidate the reaction mechanism of naphthalene alkylation with long-chain α-tetradecene (α-C14H28) over H-FAU zeolite, a reaction critical for producing high-value alkylated aromatics in industrial catalysis. By combining in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) with kinetic and thermodynamic analysis, this study quantitatively tracks the ev…

Mixed matrix membranes (MMMs) incorporating metal–organic frameworks (MOFs) are attractive for molecular recognition and separations, but precisely engineering the MOF filler structure toward maximizing its inherent nanopore separation capability remains challenging. Here, we report a fluorination strategy to functionalize MIL-101 that synergistically optimizes its pore chemical environment and i…

The objective of this work is to intensify the global rate of the nitration reaction of a vegetable oil using a micellar medium in order to synthesize a biobased cetane improver. The vegetable oil is a biodiesel composed mainly of methyl oleate. The use of micelles enables greater mass transfer between the organic and aqueous phases by solubilizing the oil within the nitrating agent contained in …

With escalating global concern regarding the unsustainability of conventional energy sources, interest in the large-scale usage of renewable alternatives has increased significantly during recent years. In the case of gaseous fuels, biomethane highlights as an optimum prospect to replace fossil natural gas owing to the physiochemical and energetical resemblance between the two gases. Acknowledgin…

In this contribution, a population balance model is grounded in a theoretical framework to investigate hydrate formation and dissociation dynamics in a marine environment. A high-resolution, finite-volume method is framed to solve the population balance equations for determining the size distribution and the corresponding surface area of hydrate particles. This formulation addresses numerous issu…

V6O13 emerges as a highly promising cathode material for aqueous zinc-ion batteries (AZIBs), owing to its unique bilayer topology that offers abundant Zn2+ storage sites and metal-like electronic conductivity. Nevertheless, the electrochemical performance of pristine V6O13 is severely hampered by its intrinsic weak van der Waals interactions, narrow interlayer spacing, and prone-to-agglomeration …

This work proposes a new preparation method for polyisocyanate with adjustable viscosity using hexamethylene diisocyanate (HDI) as a raw material. The innovation of this method lies in the continuous recovery or supplementation of HDI during the reaction process, resulting in a mass percentage of HDI in the reaction system of 30–80%. The reaction system is then heated and further reacted. The vis…

Selective conversion of glycerol to 1,2-propanediol (1,2-PDO) provides a sustainable approach to the valorization of an unavoidable by-product in biodiesel industry. However, achieving selective cleavage of the primary hydroxyl group (C1–OH) to form 1,2-PDO under hydrogen-free conditions remains a challenge. Herein, we report a CeO2–dolomite-based catalyst prepared by mechanochemical ball milling…
