“…[ 13 ] Figure 2e displays the high‐resolution C 1s spectrum, with peaks at 284.9 and 286.6 assigned to C─C and C─O/C─S bonds, respectively. [ 27,35 ] Figure 2f displays the presence of three forms of nitrogen, namely, pyridinic N (398.4 eV), pyrrolic N (400.1 eV), and graphitic N (402.2 eV), respectively, which further confirmed that N was successfully doped into the carbon.

“…The peaks at 1640 and 1493 cm −1 correspond to the stretching vibrations of the C = C bond, as documented by previous studies. [26][27][28] The peak at 1356.2 cm −1 is attributed to the C─N stretching vibration, while two characteristic peaks resulting from vibrations of the C─S bond are observed at ≈663.6 and 1237.3 cm −1 . [27,29,30] The successful doping of sulfur into the carbon framework is confirmed by both the Raman and FTIR results.…”

To make sodium‐ion batteries a realistic option for everyday energy storage, a practicable method is to enhance the kinetics of Na+ reactions through the development of structurally stable electrode materials. This study utilizes ternary Sn‐based dichalcogenide (SnS1.5Se0.5) in the design of electrode material to tackle several issues that adversely hinder the performance and longevity of sodium‐ion batteries. First, the incorporation of Se into the SnS structure enhances its electrical conductivity and stability. Second, the ternary composition restricts the formation of intermediates during the desodiation/sodiation process, resulting in better electrode reaction reversibility. Finally, SnS1.5Se0.5 lowers the diffusion barrier of Na, thereby facilitating rapid and efficient ion transport within the electrode material. Moreover, nitrogen and sulfur dual‐doped carbon (NS‐C) is used to enhance surface chemistry and ionic/electrical conductivity of SnS1.5Se0.5, leading to a pseudocapacitive storage effect that presents a promising potential for high‐performance energy storage devices. The study has successfully developed a SnS1.5Se0.5/NS‐C anode, exhibiting remarkable rate capability and cycle stability, retaining a capacity of 647 mAh g−1 even after 10 000 cycles at 5 A g−1 in half‐cell tests. In full‐cell tests, Na3V2(PO4)3//SnS1.5Se0.5/NS‐C delivers a high energy density of 176.6 Wh kg−1. In addition, the Na+ storage mechanism of SnS1.5Se0.5/NS‐C is explored through ex situ tests and DFT calculations. The findings suggest that the ternary Sn‐based dichalcogenides can considerably enhance the performance of the anode, enabling efficient large‐scale storage of sodium. These findings hold great promise for the advancement of high‐performance energy storage devices for practical applications.

“…However, after carbonization, it exhibits low wettability, necessitating doping with other elements. The addition of sulphur (S) can effectively enhance photocatalytic activity, leading to the formation of S-Doped Porous Carbon (SDPC) [13]. Through this research, we focus on analysing the effectiveness of the sulphur-doped carbon composite photocatalysis process derived from medical mask waste/TiO2.…”

The Covid-19 case requires the use of masks followed by an increase in the amount of waste in Indonesia. Another type of waste that continues to increase and is harmful to waters is Rhodamine-B (RhB). One way to treat this waste is by photodegradation method. In this research, the synthesis of S-doped porous carbon (SDPC) derived from medical mask waste was composited with TiO2, a semiconductor material, to be used as photocatalyst material. The aim of this research is to determine the effect of SDPC mass on the structure and morphology of the SDPC/TiO2 composite and the performance of Rhodamine-B degradation. The mass variations of SDPC used were 25%; 37.5%; and 50%. The process of synthesizing porous carbon by sulfonation method at a temperature of 200 °C for 6 hours and continued activation using KOH to form activated SDPC. Then the composite synthesis process was carried out by sonification process. The result show 50% SDPC/TiO2 composite has the best degradation performance with degradation percentage of 54.21% in 2 hours of irradiation time.
