Among valuable rare-earth elements, neodymium (Nd) is one of the extensively diffused metals in production of high-tech and clean-energy equipment due to its strong and light magnetic properties. China has already acquired a principal place in Nd supply to the global market, becoming a successful competitor with a higher level of utilization capacity in the country to face growing demand. Previous literature has provided some information on substance flow for a few recent years; however, they often fail to interpret better penetration about the current Chinese position of the Nd industry. Therefore, this study attempts to give a detailed examination on the emergence of Nd industry inside the framework of rare-earth utilization and supply with a special emphasis on challenges and prospective. As the frontrunner of rare-earth production, China is responsible for over 95% of the global supply, having a good market for Nd also. It is important to note that recycling Nd plays a crucial role in reducing carbon emissions by lessening the demand for raw material extraction and supporting the growth of green technologies. Finally, it is vital to strengthen the country’s regulations and policies to minimize negative environmental consequences and protect societal values.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"1 12","pages":"2621–2629 2621–2629"},"PeriodicalIF":0.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127462","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}

While accurately determining PGM concentrations in SACs is challenging, it is pivotal for effective recycling. Currently, the main methods for determining the PGM concentration in SACs are direct solid sample analysis and microwave dissolution, which face challenges such as matrix interference and the heterogeneity of samples. This study established a method for determining PGMs in SACs by inductively coupled plasma emission spectroscopy (ICP-OES) after the Cu fire assay, to achieve better detection limits for PGMs. The conditions for Cu fire assay were carefully optimized: under the optimal conditions, the losses of Pt, Pd, and Rh in the slag can be minimized to 5 ± 3, 12 ± 9, and 2 ± 2 μg, respectively. The spectral interference of Cu in determining PGMs was avoided by selecting interference-free emission lines. The established method has excellent analytical performance for Rh, with the detection limits for Pt, Pd, and Rh being 1.3, 13.8, and 0.8 g/t, respectively. The precision evaluated within 11 results of repeated measurements of four different types of real SACs ranged from 0.63% to 3.29%.

Keeping in mind the concept of “waste-to-wealth,” we have synthesized value-added microporous graphitic carbon from waste Tecoma leaves, referred to as TA, through a one-step chemical activation process and utilized it for oxygen reduction reactions (ORRs) and capacitive energy storage applications. The transformation of biomass into metal-free porous graphitic carbon having an ORR efficiency comparable to or even better than commercially available Pt/C is critical for renewable energy conversion technologies. The TA-900 sample, synthesized at 900 °C having a high surface area of 1429 m² g^–1, containing 4.41 atom % nitrogen and 4.74 atom % oxygen, demonstrated excellent ORR performance among the synthesized graphitic carbon samples at different temperatures. It showed an onset potential (<i>E</i>_onset) of 1 V and a limiting current density (<i>J</i>_L) of 6.21 mA cm^–2, comparable to 10 wt % Pt/C. Both experimental and theoretical findings suggest that the TA-900 electrocatalyst exhibited a 4e^– transfer mechanism in the electrocatalytic reduction of O₂ to H₂O. Regarding supercapacitor application, TA-900 achieved a high specific capacitance of 546 F g^–1 in acidic and 327 F g^–1 in neutral aqueous electrolyte at a current density of 1 A g^–1 in a three-electrode setup. The TA-900-based symmetrical supercapacitor (SSC) device has remarkable durability, retaining its 84% capacitance retention even after 3000 cycles at 1 A g^–1. It also achieved a notable energy density (33 Wh kg^–1 and 6.60 mWh cm^–3) and a power density (6.20 kW kg^–1 and 1320 mW cm^–3).

The current study deals with the thermochemical treatment of walnut shells using three different atmospheres, i.e., limited oxygen, nitrogen, and vacuum. The walnut shell biochars were tested for water retention capacity and hydraulic conductivity. All the synthesized biochars were then chemically treated with acid or base to increase their water retention capacity. Surface analysis was done using SEM and FTIR and suggested surface modification and hydrophilic functionalization. The highest water retention capacity was observed in untreated biochar synthesized under limited oxygen atmosphere and sodium carbonate treated biochar synthesized under nitrogen and vacuum environments. The increase in water retention can be associated with hydrophilic functionalization and microstructure of the biochar surface, modified by chemical treatment, supported by contact angle measurements. Incorporation of biochar with soil (locally sourced) shows an enhancement in water retention capacity and lowering of hydraulic conductivity. The highest enhancement for water retention was observed to be 11% for the biochar–soil mixture (5%) using sodium carbonate treated vacuum biochar as compared to the control.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 1","pages":"29–38 29–38"},"PeriodicalIF":0.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091677","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}
