“…Therefore, the organic ligands are removed and the catalyst consists of only cobalt oxide after calcination. This agrees with previous reported decomposition of ZIF-67 using Thermo-gravimetric analysis and XRD [40][41][42]. The XPS spectra of the calcined samples at Co (2p 3/2 ) are shown in Fig.…”

Aristolochic acid I is a toxic compound found in the genus of Aristolochia plants, which are commonly used as herbal cough treatment medicines. To remove the aristolochic acid I in extract efficiently and selectively, a molecularly imprinted polymer composed of ethylimidazole ionic liquid‐based zeolitic imidazolate framework‐67 was synthesized and used as the adsorbent. Under the conditions optimized by the software design expert, the sorbent showed highest adsorption amount of 34.25 mg/g in methanol/water (95:5, v/v) at 39°C for 138 min. The sorbent was then applied to solid phase extraction to isolate aristolochic acid I from the extract of the herbal plant Fibraurea Recisa Pierre. 0.043 mg/g of aristolochic acid I was obtained after the loading, washing, and elution processes. The limit of detection of 2.41 × 10−5 mg/mL and good recoveries provided evidence for the accuracy of this method.

“…The band at 1584 cm –1 was due to the C=N stretching mode. Furthermore, the peaks at 2929 and 3135 cm –1 could be due to the stretching mode of C–H from the aromatic ring and the aliphatic chain in 2‐MIM, respectively , . According to the literature, the IR peaks of Cu–N, Fe–N and Ni–N stretch at 460, 855 and 525 cm –1 respectively .…”

Bimetallic Oxide Hollow Structures Induced by Surface Coordination of ZIF‐67

Bimetallic hollow nanomaterials which are composed of two different metal/metal oxide materials show great potentials owing to their unique structural features. Here, the second metal ions were introduced into the surface of ZIF‐67 by ultrasonication to form bimetallic hollow complexes, and the coordination between the second metal ions and ZIF‐67 colloidal crystals are further investigated. A series of bimetallic complexes has been synthesized by incorporating FeIII, CuII and NiII into the coordinating block of ZIF‐67. After calcination in oxygen, these as‐prepared transformed to Fe/Cu/Ni doped Co3O4 hollow nanoboxes. We found a facile and general method to form bimetallic complexes by complexing the second metal ions with ZIF‐67 surface ligands and calcining to form bimetallic hollow nanoboxes.
