The morphology and structure of the nanoadsorbent were analyzed using TEM, SEM, XRD, FT-IR, BET, EDS, and VSM. The adsorption studies demonstrated a peak Cd (II) adsorption capacity of 400.00 mg/g under conditions of 25°C, pH 6, using 0.05 g/100 mL of NiFe₂O₄-HNTs-chitin, with equilibrium achieved within just 10 min. Adsorption kinetics follow a pseudo-second-order model, and the isothermal data corresponded with the Langmuir model, suggesting monolayer adsorption on the adsorbent surface and a chemically controlled rate-determining step. The thermodynamic analysis showed that the uptake process is both spontaneous and exothermic (<i>ΔH</i> = −511.028 kJ/mol, <i>ΔG</i> = −32.78 kJ/mol). Remarkably, the adsorbent maintained high uptake and release effectiveness even after four cycles, with the primary mechanism of Cd (II) removal attributed to chelation through oxygen (O) and nitrogen (N) atoms. These results demonstrate that NiFe₂O₄-HNTs-chitin is a highly efficient and recyclable sorbent for removing Cd (II) ions from water, with significant practical applicability.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 9","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent decades, porous nanomaterials such as covalent organic frameworks (COFs) have been developed to address the challenges of homogenous catalysts, particularly rapid deactivation and recycling; however, achieving high catalyst loading with stable catalytic performance remains a significant challenge. In this study, we developed a nitrogen-enriched COF with large channels by using bis(biguanide) (DG) and triphenylbenzene (TPB) as building blocks. The bis(biguanide)s offer multiple binding sites, enabling high binding affinity, resulting in the uniform immobilization of Pd(II) with high loading to form Pd/DG-COF. The intersecting TPB structure provides a large pore size, allowing for improved mass transport for efficient catalysis. Additionally, the inherent physiochemical properties of DG and TPB result in potential cation-π interactions and π-π interactions with benzene-based substrates, which significantly accelerate the catalytic activity, resulting in a good catalytic performance, with turnover frequency (TOF) of approximately 5000 h⁻¹ and broad substrate applicability. Pd/DG-COF maintained stable performance and remarkable recyclability, with no significant loss of activity observed after 10 catalytic cycles.
