“…Materials with greater surface areas typically have higher capacitance values because they offer more electrochemical active sites for storing charge. 103–105 It may be inferred that a higher SSA of BaFe 2 O 4 (29.3988 m 2 g −1 ) might ease the ion diffusion, and the combination of cathode-active Ba (2A) and anode-active Fe (8B) might be a good choice to obtain better electrochemical properties such as broader working potential, lower charge transport resistance ( R ct ) and the equivalent series resistance ( R s ). The maximum areal capacitance of the materials was recorded as 390 mF cm −2 , 503 mF cm −2 , and 682 mF cm −2 at the current of 0.85 mA for Cu 2 O, BaFe 2 O 4 , and BaFe 2 O 4 @Cu 2 O, respectively.…”

“…However, it seems that its stability is an issue, as the degradation of the dye slows down and even approaches the result for ZnS@CNTs at 360 min. The kinetic constants, k, were calculated from the linear fitting of ln(c 0 /c i ) = kt [35] and, indeed, FeS shows the highest value over the total duration of the photodegradation process (k = 5.73 × 10 −3 min −1 ), whereas FeZnS has the lowest k = 3.17 × 10 −3 min −1 . The high photocatalytic efficiency of FeZnS@CNTs in the first 30 min compared to ZnS@CNTs could be due to the higher amount of photogenerated carriers originating from the absorption superiority of FeZnS.…”

A wide ranging scientific interest in developing new and simple preparation methods for highly catalytic bimetallic sulfides provided our motivation to explore the possibility of using the pulsed electrodeposition technique for the decoration of a carbon nanotubes forest. The carbon nanotubes were obtained using the hot-filament chemical vapor deposition technique. A non-thermal plasma treatment enabled the controlled creation of defects on the carbon nanotubes’ surface. These defects served as anchoring sites for the subsequent deposition of Fe and Zn nanoparticles using the pulsed electrodeposition technique. Our findings showed that only in the case of Fe deposition prior to Zn provided the formation of FeZn bimetallic-based nanoparticles, with Zn present mainly on the outer surface of the Fe core. To induce sulfurization, a thermal treatment in sulfur vapor was conducted at 500 °C, and the obtained heterostructure consisted of Fe0.3Zn0.7S as the main phase, with the minor presence of ZnS and S residues, which was deduced from the XRD results. This study provides thorough imaging of the process, presenting for each preparation step SEM/HR-TEM findings, coupled with EDS chemical analyses. The samples were tested for photocatalytic degradation of methyl blue dye to demonstrate the photoactive behavior of the heterostructure.

“…Pre-treatment methods include thermal pre-treatment, mechanical pre-treatment and chemical pre-treatment. Thermal pre-treatment refers to roasting [52] and pyrolysis [53][54][55][56]; mechanical pre-treatment contains grinding, cryogenic-grinding [57] and attrition [28]; and chemical pre-treatment mainly refers to the advanced oxidation processes [50,58].…”

Among the technologies used for spent lithium-ion battery recycling, the common approaches include mechanical treatment, pyrometallurgical processing and hydrometallurgical processing. These technologies do not stand alone in a complete recycling process but are combined. The constant changes in battery materials and battery design make it a challenge for the existing recycling processes, and the need to design efficient and robust recycling processes for current and future battery materials has become a critical issue today. Therefore, this paper simplifies the current treatment technologies into three recycling routes, namely, the hot pyrometallurgical route, warm mechanical route and cold mechanical route. By using the same feedstock, the three routes are compared based on the recovery rate of the six elements (Al, Cu, C, Li, Co and Ni). The three different recycling routes represent specific application scenarios, each with their own advantages and disadvantages. In the hot pyrometallurgical route, the recovery of Co is over 98%, and the recovery of Ni is over 99%. In the warm mechanical route, the recovery of Li can reach 63%, and the recovery of graphite is 75%. In the cold mechanical route, the recovery of Cu can reach 75%, and the recovery of Al is 87%. As the chemical compositions of battery materials and various doping elements continue to change today, these three recycling routes could be combined in some way to improve the overall recycling efficiency of batteries.
