Metal–organic frameworks (MOFs) are attractive porous materials for electrocatalytic applications associated with carbon-free energy storage and conversion. This type of material usually requires a post-treatment to be used as electrocatalyst. The present work comprehensively investigates the electrochemical activation [email protected] composite that produces outstanding performance water oxidation reaction at neutral pH. A detailed characterization reveals electroactivation participation oxygen evolution (OER) leads significant increase in electroactive population cobalt centers. It is shown an applied potential OER region results faster Co-MOF without affecting intrinsic properties active centers, evidenced by unique linear correlation between current cobalt. In addition, structural level, it causes partial disruption Nafion adlayer, well morphological changes Co–MOF particles from compact, rounded morphology, before activation, more open expanded structure, after electroactivation; concomitant number surface–exposed Interestingly, these centers retain their coordinative chemistry laminar distribution nanosheets nanoscale, which consistent preservation activity potential–induced activation. this scenario, suggest only electroactivated good accessibility electrolyte electrochemically active. provides better understanding processes underlying pH boosting reaction.

Heavy metal contamination in water sources poses a significant threat to environmental and public health, necessitating effective remediation strategies. Nanomaterial-based approaches have emerged as promising solutions for heavy removal, offering enhanced selectivity, efficiency, sustainability compared traditional methods. This comprehensive review explores novel nanomaterial-based remediation, focusing on factors such regeneration, scalability, practical considerations. A systematic literature search was conducted using multiple academic databases, including PubMed, Web of Science, Scopus, identify relevant articles published between 2013 2024. The identifies several nanomaterials, graphene oxide, carbon nanotubes, metal-organic frameworks, which exhibit high surface areas, tunable chemistries, excellent adsorption capacities. Surface functionalization with specific functional groups (e.g., carboxyl, amino, thiol) significantly enhances the selectivity target ions. Advances regeneration strategies, chemical desorption, electrochemical photocatalytic improved reusability cost-effectiveness these materials. Scalability remains critical challenge, but recent developments synthesis methods, green continuous-flow synthesis, offer large-scale production. stability longevity nanomaterials been through modification development hybrid nanocomposites. Integrating existing treatment infrastructure combining them other techniques, membrane filtration can enhance overall efficiency feasibility. In conclusion, hold immense promise revolutionizing advancing sustainable management practices. As future research is geared towards retrofitting plants, it equally mitigate unintended health consequences associated widespread production use their leachability into systems persistence.
