Innovative Green Alginate-Cellulose Composite for Light Lanthanides: Experimental Design and Comprehensive Studies on Kinetics, Equilibrium, Thermodynamics, and Reusability
This study proposes the alginate-cellulose composite as an ecological, sustainable adsorbent for light lanthanide sorption. The structure, morphology, qualitative and quantitative compositions, average diameter, and pHpzc of the composite were discussed in great detail. Using the batch approach, sorption trials were performed to evaluate the metal sorption performance. The maximum lanthanide accumulation was attained at pH 5.0 and a dosage of 0.05 g. The uptake kinetics are successfully explained by the Ho and McKay model, whereas the equilibrium data is best represented by the Langmuir equation. The presence of Cl-, NO3-,...

The Use of 5-Hydroxymethylfurfural (5-HMF) in Multi-component Hantzsch Dihydropyridine Synthesis
ChemSusChem. 2024 Mar 20:e202301782. doi: 10.1002/cssc.202301782. Online ahead of print.ABSTRACTThe renewable 5-hydroxymethylfurfural (5-HMF) has gained a wide interest from the chemistry community as a valuable biobased platform opening the way to further functionalization. Despite an impressive number of publications reporting either its preparation or its functionalization, its direct use in fine chemistry, and especially in multi-component reaction (MCR), is less reported. Here, we report a complete study of the use of 5-HMF in the Hantzsch dihydropyridines synthesis. The strategy was applied to a scope of β-dicarbony...

Challenges and recent progress on solid-state batteries and electrolytes, using qualitative systematic analysis. A Short review
ChemSusChem. 2024 Mar 20:e202301808. doi: 10.1002/cssc.202301808. Online ahead of print.ABSTRACTThe rise in the energy demand, the need to decrease the use of fossil fuels, expanding investments in renewable energy and boosting the electric vehicle market, opens the door for new technologies in clean energy accumulators. Lithium-ion batteries are the most advanced technology in the market, but have safety concerns due to the flammability of the electrolyte, which opens the door for innovations. One of these innovations is the solid-state batteries (SSB), which, by using solid electrolytes, do not have the flammable risk, b...

Monitoring the Morphological Changes of Skeleton-PtCo Electrocatalyst during PEMFC Start-Up/Shut-Down probed by in situ WAXS and SAXS
In this study, a combination of in situ small-angle and wide-angle X-ray scattering (SAXS & WAXS) techniques were employed to establish correlations between structural parameters (crystal phase, quantity, and size) of a highly active skeleton-PtCo (sk-PtCo) catalyst and their degradation cycles within the potential range of the start-up/shut-down (SUSD) conditions. Despite the complex case of the sk-PtCo catalyst comprising two distinct fcc alloy phases, our complementary techniques enabled in situ monitoring of structural changes in each crystal phase in detail. Remarkably, the in situ WAXS measurements uncovered two ...

Acid-catalyzed activation and condensation of the =C5H bond of furfural on aldehydes, an entry point to biobased monomers
ChemSusChem. 2024 Mar 19:e202400289. doi: 10.1002/cssc.202400289. Online ahead of print.ABSTRACTFurfural is an industrially relevant biobased chemical platform. Unlike classical furan, or C-alkylated furans, which have been previously described in the current literature, the =C5H bond of furfural is unreactive. As a result, on a large scale, C=C and C=O bond hydrogenation/hydrogenolysis is mainly performed, with furfuryl alcohol and methyl tetrahydrofuran being the two main downstream chemicals. Here, we show that the derivatization of the -CHO group of furfural restores the reactivity of its =C5H bond, thus permitting its...

Selective recovery of battery-grade Li2CO3 from spent NCM cathode materials using a one-step method of CO2 carbonation recovery without acids or bases
ChemSusChem. 2024 Mar 19:e202400459. doi: 10.1002/cssc.202400459. Online ahead of print.ABSTRACTThe recovery of spent lithium-ion batteries by traditional acid leaching is limited by serious pollution, complicated technology, and the low purity of Li2CO3. To address the problems of the traditional acid leaching process and increasing demand for decarbonization, a technique for the selective carbonation leaching of Li and the recovery of battery-grade Li2CO3 by a simple concentration precipitation process without acids or bases was developed. The coupling of CO2 and reducing agents could effectively promote the precipitatio...

Laser-Induced Preparation of Anderson-Type Polyoxometalate-Derived Sulfide/oxide Electrocatalysts for Electrochemical Water Oxidation
ChemSusChem. 2024 Mar 19:e202301862. doi: 10.1002/cssc.202301862. Online ahead of print.ABSTRACTDeveloping cost-effective and high-active electrocatalysts is vital to enhance the electrocatalytic performance for oxygen evolution reaction (OER). However, traditional pyrolysis methods require complicated procedures, exact temperatures, and long reaction times, leading to high costs and low yields of electrocatalysts in potential industrial applications. Herein, a rapid and economic laser-induced preparation strategy is proposed to synthesize three bimetallic sulfide/oxide composites (MMoOS, M = Fe, Co, and Ni) on a nickel fo...

Interface Defects Dependent on Perovskite Annealing Temperature for NiOX-Based Inverted CsPbI2Br Perovskite Solar Cells
In this study, a new type of interface defects in NiOX-based CsPbI2Br solar cells is reported. That is the Pb2+ from CsPbI2Br perovskites can diffuse into the lattice of NiOX surface as the annealing temperature of perovskites changes. The diffusion of Pb2+ increases the ratio of Ni3+/Ni2+ on the surface of NiOX, leading to an increase in the density of trap state at the interface between NiOX and perovskites, which eventually results in a serious decline in the photovoltaic performance of solar cells.PMID:38487956 | DOI:10.1002/cssc.202301722 (Source: ChemSusChem)

Multifunctional Interface Modification Enables Efficient and Stable HTL-Free Carbon-Electroded CsPbI2Br Perovskite Solar Cells
ChemSusChem. 2024 Mar 15:e202400223. doi: 10.1002/cssc.202400223. Online ahead of print.ABSTRACTIn recent years, hole transport layer-free all-inorganic CsPbI2Br carbon-electroded perovskite solar cells (C-PSCs) have garnered significant attention due to a trade-off between stability and photovoltaic performance. However, there are inevitably many defects generated at the surfaces or grain boundaries of CsPbI2-Br perovskite films, which will serve as carrier non-radiative recombination centers, and CsPbI2-Br perovskite films are sensitive to water molecules to degrade, together with energy level mismatch between CsPbI2Br p...
