Interfacial Electron‐Modulated Pt Sites on Self‐Supported NiCoP Nanosheets for Enhancing Hydrogen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
Using a hierarchical multilevel‐structure strategy, we design and prepare a self‐supported Pt/NiCoP/CF catalyst with a strong electron transfer effect between Pt and NiCoP. This catalyst realizes highly efficient HER performance under full pH range, outperforming commercial Pt/C catalyst.

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

open access: yesCarbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

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 ...

Evaluation of the Nutrient Components of Flours, Color Profile, and Sensory Qualities of Cake From Wheat and Celosia argentea Seed Blends

open access: yesFuture Postharvest and Food, EarlyView.
Composite flour was developed with 5%, 10%, 15%, and 20% inclusion of Celosia seeds flour. The flour was used in the production of cake. Cake made with 5% composite flour compared favorably with cake from 100% wheat flour. ABSTRACT Nutritional benefits and physical appearance are of great importance in determining the acceptance of confectionary ...
