“…This phenomenon manifests that the 70% BiOCl/CAU-17 composite has a wide pore size distribution with abundant but irregular pore structures, which may originate from the formation of the 2D/2D heterostructure. 41 What's more, the S BET , average pore volume ( V pore ), and pore size ( D pore ) of BiOCl, CAU-17, and 70% BiOCl/CAU-17 composite are displayed in Table 1. The S BET of BiOCl, CAU-17, and 70% BiOCl/CAU-17 composite were 15.46, 93.15, and 81.95 m 2 g −1 , showing that the introduction of CAU-17 can increase the surface area of BiOCl.…”

“…There are many methods to promote the catalytic activity of nanomaterials, for instance, defect engineering, metal element doping or loading, , active crystal regulation, , interface engineering, and so on. , However, in contrast to other methods, it is easier to prepare catalysts for oxygen-containing compounds with oxygen defects. The formation of oxygen vacancies has become a promising method to promote catalytic activity.…”

Although the application of nanozymes has been widely studied, it is still a huge challenge to develop highly active and multifunctional nanozyme catalysts with a wider application prospect. Co 3 O 4 /CoFe 2 O 4 hollow nanocubes (HNCs) with oxygen vacancies were proposed in this study, which had a porous oxide heterostructure with CoFe 2 O 4 as the core and Co 3 O 4 as the shell. The Co 3 O 4 /CoFe 2 O 4 HNCs had three enzyme activities: peroxidase-like, oxidase-like, and catalase-like. Combining XPS depth profiling with density functional theory (DFT), the catalytic mechanism of peroxidase-like activity was explored in depth, which was mainly originated from •OH produced by the synergistic effect between the outer oxygen and inner oxygen and electron transfer between Co and Fe. A colorimetry/smartphone dual sensing platform was designed based on the peroxidase-like activity. Especially, a multifunctional intelligent sensing platform based on deep learning-YOLO v3 algorithm-assisted smartphone was constructed to realize real-time and rapid in situ detection of L-cysteine, norfloxacin, and zearalenone. Surprisingly, the detection limit of norfloxacin was low at 0.015 μM, which was better than that of the newly published detection method in the field of nanozymes. Meanwhile, the detection mechanism of L-cysteine and norfloxacin was successfully investigated by in situ FTIR. In fact, it also showed outstanding applications in detecting L-cysteine in the food environment and norfloxacin in drugs. Furthermore, Co 3 O 4 /CoFe 2 O 4 HNCs also could degrade 99.24% of rhodamine B, along with good reusability even after 10-cycle runs. Therefore, this work provided an in-depth understanding of the synergistic effect between the outer and inner oxygen in the reaction mechanism and an efficient method for establishing a deep-learning-assisted intelligent detection platform. In addition, this research also offered a good guideline for the further development and construction of nanozyme catalysts with multienzyme activities and multifunctional applications.
