Transition metal phosphides (TMPs) are emerging as promising electrocatalysts for water splitting, a key process in green fuel production. Herein, we synthesized a series of bimetallic NiCoMOFs with varying nickel to cobalt ratios, followed by a phosphating process using sodium hypophosphite to enhance their OER activity. The resulting NiCoX-P catalysts, characterized by petal-like nanosheet structures, were thoroughly analyzed using FT-IR, SEM, TEM, XRD, XPS, and EDX techniques. Among the synthesized catalysts, NiCo1-P demonstrated superior OER performance, achieving a current density of 10 mA cm⁻² at an overpotential of 350 mV and 50 mA cm⁻² at 497 mV in a 1.0 M KOH electrolyte. Its remarkable stability was confirmed through 20 h of chronoamperometric testing and 1000 cyclic voltammetry cycles without significant activity loss. The superior performance of NiCo1-P is ascribed to its distinctive porous architecture, which promotes efficient mass and charge transport, along with the synergistic effects resulting from its optimized bimetallic composition. This research highlights the potential of NiCo1-P as an efficient and stable electrocatalyst for OER applications, paving the way for advancements in sustainable energy technologies.</p></div>","PeriodicalId":676,"journal":{"name":"Journal of the Iranian Chemical Society","volume":"23 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146083006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trimethoprim served as the template molecule in both polymer systems.

Adsorption isotherm experiments demonstrated maximum adsorption capacities of 1.5275 µmol/g for MIP1-Tri and 2.10 µmol/g for MIP2-Tri (based on 0.2 mg of polymer), fitting well with the Langmuir model, which indicated monolayer adsorption on homogeneous binding sites.
