“…1 Among these, hydrogen (H 2 ), due to its high combustion value and zero percent environmental pollution, is an ideal source of clean renewable energy. 2,3 Mostly, hydrogen is produced at the industrial level by the stream cracking method, which consumes a huge amount of fossil fuels and thus causes environmental pollution. 4 Among all the reported methods, the production of H 2 gas via the electrolysis of water is considered the simplest and most practical.…”

“…This is similar to the previous findings that Pd/Fe 3 O 4 or Pd–In nanoparticles could be used as electron and hydrogen atom carriers facilitating the degradation of organic compounds. , XPS spectra of Fe in spent Fe-ZSM-5 became broader, and its intensity decreased(Figure S6), and the Fe concentration on the surface of spent Fe-ZSM-5 through XPS surface composition analysis decreased, showing that Fe 2 O 3 was consumed and released during the electrochemical process (Table S5) and that Fe 2 O 3 may be used as an active site. It was reported that Fe 2 O 3 used as the active site such as in Fe 2 O 3 –N-doped carbon, Fe 2 O 3 /FeP, Fe 2 O 3 /NiFe-LDHs, and so forth had a better electrocatalytic performance for the HER and OER, − which usually occur during the electrolytic process. , During the HER and OER processes, H* can be generated from the reduction of water through the Volmer process (eqs –), , and • OH could be generated on the DSA anode by oxidation of water (eq ). …”

Devising cost-effective electrochemical catalyst system for the efficient degradation of chlorinated aromatic compounds is urgently needed for environmental pollution control. Herein, a Fe-ZSM-5 zeolite was used as a suspended catalyst to facilitate the degradation of lindane as a model chlorinated pesticide in an electrochemical system consisting of the commercial DSA (Ti/RuO 2 -IrO 2 ) anode and graphite cathode. It was found that the Fe-ZSM-5 zeolite greatly accelerated the degradation of lindane, with the degradation rate constant more than 8 times higher than that without Fe-ZSM-5. In addition, the Fe-ZSM-5 zeolite widened the working pH range from 3 to 11, while efficient degradation of lindane in the absence of Fe-ZSM-5 was only obtained at pH ≤ 5. The degradation of lindane was primarily due to reductive dechlorination mediated by atomic H* followed by • OH oxidation. Fe-ZSM-5 zeolite could enrich lindane, H*, and • OH on its surface, thus provided a suitable local environment for lindane degradation. The Fe-ZSM-5 zeolite exhibited high stability and reusability, and reduced the energy consumption. This research provides a potential reduction–oxidation strategy for removing organochlorine compounds through a cost-efficient Fe-ZSM-5 catalytic electrochemical system.

The research was done on the creation and use of bi‐metal sulfide thin film, Nd2S3:Ni9S8. 41 nm‐sized crystallites with 80% crystallinity were found in the material. The evaluated optical characteristics showed a 2.9 eV band gap energy. The presence of Nd3d, S2p, and Ni2p in the created material was confirmed by X‐ray photoelectron spectroscopy. Voltammetry tests were carried out to assess the electrochemical characteristics. With a value of 750 Fg−1, the findings obtained showed remarkable supercapacitive capability. Additionally, a thorough examination was done to learn more about the material's potential as a photocatalyst. Malachite green dye, fuberidazole, and phenol were used as environmental contaminants to test the thin films' photocatalytic degradation effectiveness. The highest degradation was found for fuberidazole with a rate constant of 2.46x10−2 min−1. The results demonstrated the versatility of thin films and their efficacy in degrading these pollutants, highlighting their potential for environmental remediation applications.
