The pursuit of sustainable energy solutions to address environmental challenges and crises has driven significant interest in electrocatalytic water splitting. However, the efficiency this process is hindered by sluggish kinetics anodic oxygen evolution reaction (OER). To overcome this, we synthesized two isoreticular cobalt-based metal-organic frameworks (MOFs), MOF-74 MOF-274, with different pore sizes (16.50 23.37 Å, respectively), where exhibited stronger Fe(III) adsorption as a result its confined nanosized channels. Electrochemical activation transformed these Co-MOF precatalysts into Fe-doped CoOOH nanosheets uniform elemental distribution, enhancing their OER performance. It revealed strengthened Co-O-Fe electronic interactions MOF-74-Fe X-ray photoelectron spectroscopy analysis, MOF-74-Fe-OER achieved decent activity show lower overpotential 288 mV at 10 mA cm-2 compared MOF-274-Fe-OER (357 mV). Furthermore, long-term stability tests confirmed robust durability, retaining 96.9% initial performance over h. These results underscore critical role pore-engineered MOF optimizing modulation catalytic for oxidation.

Doping undermines fairness in sports and threatens athlete health, while conventional detection methods like LC-MS GC-MS face challenges such as complex procedures, matrix interferences, lengthy processing times, limiting on-site applications. Two-dimensional (2D) materials, including graphene, MoS2, metal–organic frameworks (MOFs), offer promising solutions due to their large surface areas, tunable electronic structures, special interactions with doping agents, hydrogen bonding, π-π stacking, electrostatic forces. These materials enable signal transduction through changes conductivity or fluorescence quenching. This review highlights the use of 2D detection. For example, reduced graphene oxide–MOF composites show high sensitivity for detecting anabolic steroids testosterone, NiO/NGO nanocomposites exhibit strong selectivity stimulants ephedrine. However, environmental instability production costs hinder widespread application. Future efforts should focus on improving material stability chemical modifications, reducing costs, integrating these into advanced systems machine learning. Such advancements could revolutionize detection, ensuring protecting health.
