A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

open access: yesEcoEnergy, EarlyView.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

Optimizing Intermediate Adsorption on FeNi3 Alloy by Substrate Defect‐Engineering for Enhanced Oxygen Electrocatalysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The presence of carbon edge defects and graphitic valley nitrogen significantly alters the energy band structure of the catalyst, enhancing the desorption of oxygen‐containing intermediates and thereby improving the performance of the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and zinc‐air battery (ZAB).

Atmosphere‐Regulated Pyrolysis Switches ORR Pathway on Iron‐Based Catalyst for H2O2 Synthesis and Zn‐Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Two Fe‐based electrocatalysts with different ORR selectivity were synthesized from a FeMOF in N2 or air atmosphere, which show promising prospects in Zn‐air battery and H2O2 production. Developing simple methods to achieve flexible regulation of oxygen reduction reaction (ORR) selectivity is essential for sustainable energy technologies, yet remains ...
