“…The peaks that are more noticeable in the spectrum are diminished in terms of the final spectrum; Idris et al (2022) maintain that this is due to the degradation of the substrate in the process of generating electrical energy during its operation, since the microorganisms use many of these compounds as food for their functioning [64]. Other authors, such as Putra-Hidayat et al ( 2022), reported that, as seen through the FTIR spectrum, the adsorbent (MOF type HKUST-1, UiO-66, and ZIF-8) was able to eliminate Cr (VI) in an MFC as well as identify the presence of bond Zn-N atomic structures within the ligand 2-methylimidazole, the carboxylic acid group (C-OH), carboxylate (O-H), aromatic bonds derived from the benzene structure (C=C), and carbonyl bonds (C=O) [65].…”

The increasing generation of wastewater with high levels of pollutants has become a serious environmental challenge. In this context, sustainable technologies are required to treat wastewater efficiently. Therefore, it was proposed to evaluate the effect of the biomass of Chlorella sp. on the removal of cadmium and chemical oxygen demand (COD) from municipal wastewater in the district of Urpay, Pataz, La Libertad, Peru, and the generation of electric power through single-chamber microbial fuel cells (MFC). An experimental design was applied, where nine treatments were carried out evaluating three doses of Chlorella sp. (10%, 20% and 30%) at pH values of 6.5, 7.0, and 7.5 of the residual water. Managing to generate peak current and voltage values of 4.61 mA and 1118.5 mV in the MFC at a pH of 7.5 with a dose of 30% of Chlorella sp., this same MFC managed to decrease concentrations of cadmium and COD by 97.5 and 15% in 25 and 15 days, respectively. This investigation demonstrated the importance of Chlorella sp. for the reduction in these two parameters, managing to provide a new method for the elimination of these pollutants in wastewater.

“…13 MOFs possess pore sizes and shapes that can be adjusted, a wide surface area, and a high affinity for different organic dyes. [14][15][16] UiO-66, a MOF sub-class, is composed of a Zr metal cluster that binds with the H 2 BDC ligand (1,4 benzenedicarboxylic acid) to create a framework and has been extensively employed as a dye adsorbent. 17 However, generally, UiO-66 is a microporous material and is oen synthesized by solvothermal methods.…”

Aqueous Aluminum‐air batteries (AABs) hold promise for advancing high‐energy density storage systems in future technologies. However, their widespread practical deployment is limited by the inherent hydrogen side reactions in Aluminum (Al) and incomplete cathodic reactions. To address these challenges, the Al‐sodium persulfate (Na2S2O8) system is introduced as an alternative to traditional AABs. Utilizing Na2S2O8 allows to simultaneously achieve three critical objectives, namely, eliminating the need for a cathode catalyst, increasing the system voltage from 1.4 to 2 V, and reducing the hydrogen evolution reaction (HER). Three distinct configurations of the Aluminum electrochemical energy system (Al‐EES) using Na2S2O8: static, flow, and gel are developed. The static configuration demonstrates a performance 1.7 times superior to that of traditional AABs. The flow configuration of Al‐EES achieves a discharge duration of 77 h, which is three to four times longer than that of AABs and exhibits an energy density of 2,650 Wh kgAl−1. This emerging technology has the potential to significantly enhance electric vehicles by providing powerful, efficient, cost‐effective, and durable power‐generation devices.
