Optimizing factors like activation holding time is the key to achieving AC with high surface area and hierarchical pores. Herein, AC from water hyacinth, a common biowaste, was prepared using the KOH activation process, with varied holding times (∼0.5, 1.5, and 2.5 h) to study their impact on surface area and specific capacitance. HAC2 (activation holding time 1.5 h) exhibited an elevated surface area of ∼540 m2 g–1. The optimal HAC2 electrode afforded a high specific capacitance of ∼323 F g–1 at 1 A g–1. Considering a practicability perspective, HAC2 was used as an electrode material in aqueous and organic symmetric supercapacitor devices, achieving specific capacitances of ∼173 and 34 F g–1 at 0.5 A g–1. To achieve a high specific capacitance and a high potential window, the MoO3//HAC2 device was assembled. This device achieved a high specific capacitance of ∼104 F g–1 at 0.5 A g–1 with an outstanding energy density of 28.58 W h kg–1 at 351 W kg–1 power density and a capacity retention of ∼86% after 10,000 cycles. The developed device can power a digital clock and an LED, indicating that it can be potentially used as an energy storage device.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 5","pages":"796–806 796–806"},"PeriodicalIF":0.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we have synthesized AC using wood apple shell (WAS) as the biomass and one-step chemical activation with zinc dichloride (ZnCl2). The prepared WAS-AC powder was activated at different temperatures ranging from 600 to 800 °C. Structural analysis verified the formation of an amorphous structure and high specific surface area of 942 m2 g–1 with a pore volume of 0.2 cm3 g–1, whereas the ID/IG ratio increased with the activation temperature, confirming the graphitization and defect control within the WAS-AC powder. Furthermore, the electrochemical performances of the prepared WAS-AC electrodes were examined in a neutral electrolyte (1 M Na2SO4); the WAS-AC700 electrode achieved the highest specific capacitance of 210 F g–1 at a current density of 0.5 A g–1 and a capacitive retention of 96% after 5000 cycles at a current density of 16 A g–1. Additionally, the symmetric Swagelok cell-type electrochemical capacitor (EC) device based on WAS-AC700 electrodes and 1 M Na2SO4 electrolyte demonstrated a 72 F g–1 specific capacitance at a 0.5 A g–1 current density and energy densities of 9.93/6.67 Wh kg–1 at power densities of 250/8000 W kg–1. These results highlight the promising application of wood apple shell-derived activated carbon for high-performance EC.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 5","pages":"755–765 755–765"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multicomponent alloys, especially those of the Ti-V-Nb-Cr system, have garnered significant attention because of the possibility of fine-tuning the hydrogen storage properties by compositional control. However, most of the investigations on multicomponent alloys rely on high-purity elements as feedstock materials, which can have a substantial environmental impact due to the energy-intensive processes required to achieve such purity levels. In this work, we propose an alternative approach by utilizing Ti6Al4V alloy (ASTM F136) scraps from the biomedical industry as feedstock material to produce Ti18Nb23V24Cr33Al2. The alloy was synthesized by using an arc-melting process, combining Ti6Al4V scraps with other pure elements. Structural analysis using X-ray diffraction (XRD) and scanning electron microscopy (SEM) revealed the formation of a microstructure composed predominantly by a body-centered cubic (BCC) solid solution with a small micro segregation providing additional microstructural insights. The Ti18Nb23V24Cr33Al2 alloy exhibited a hydrogen storage capacity of 2.75 wt % H2 with room temperature reversibility, presenting hydrogen storage properties comparable to those of a (TiVNb)65Cr35 alloy produced only from high-purity elements.This study presents a sustainable approach to producing Ti18Nb23V24Cr33Al2 alloy from Ti6Al4V machine chips, achieving efficient hydrogen storage with reduced environmental impact.","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 5","pages":"807–814 807–814"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssusresmgt.5c00054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
