“…The crystal structure of ZIF-8, BiOBr, ZZ-110, and BZ-9 were probed by performing XRD measurements, as can be ascertained from Figure 1 a. The peak shape and position of the prepared ZIF-8 were consistent with the simulated ZIF-8 in the literature, while its characteristic peaks were at 2θ = 7.28°, 10.24°, 12.74°, and 16.48°, which correspond to the plane of (110), (200), (211), and (220) [ 27 ]. After the hydrothermal reaction of ZIF-8 took place, the characteristic peaks of ZnO appeared in the diffraction peaks, which were located at 31.766°, 34.418°, 36.251°, and 47.535°, respectively, which could be ascribed to JCPDS No.…”

Photocatalytic technology is considered an ideal approach for clean energy conversion and environmental pollution applications. In this work, a bifunctional BiOBr/ZIF-8/ZnO photocatalyst was proposed for removing phenols in wastewater and generating hydrogen peroxide. Insights from scanning electron microscopy measurements revealed the well-dispersion of ZIF-8/ZnO was on the BiOBr layer, which could effectively prevent agglomeration of ZIF-8 and facilitate the separation of carriers. In addition, the optimal H2O2 yield of the BiOBr/ZIF-8/ZnO sample could reach 116 mmol·L−1·g−1 within 2 h, much higher than that of pure BiOBr (with the value of 82 mmol·L−1·g−1). The optimal BiOBr/ZIF-8/ZnO sample could also remove 90% of the phenol or bisphenol A in 2 h, and its kinetic constants were 3.8 times and 2.3 times that of pure BiOBr, respectively. Based on the analysis of the various experimental characterizations, the photocatalytic mechanism of the S-scheme BiOBr/ZIF-8/ZnO composite for the degradation of phenolic pollutants and generation of H2O2 was proposed. The formation of the heterojunction and the oxygen vacancy work together to significantly improve its photocatalytic efficiency. In addition, the BiOBr/ZIF-8/ZnO catalyst has a certain impact on the degradation of phenol in actual wastewater, providing a way to effectively remove refractory pollutants and generate H2O2 in actual water.

“…The utilization of various types of 2D nanomaterials as OSN membranes is steadily increasing due to their exceptional performances. The competence of new types of 2D membranes such as WS 2 , 84 NH, 85 HNb 3 O 8 , 86 VMT, 87 o-2DZTC, 88 and DLC, 89 in this field has begun to be explored. Their performances are labeled as “others” in Fig.…”

“…8b. Wu et al 84 produced a WS 2 -ZIF-8 (2D–3D nanocomposite) membrane, having the highest methanol permeance of 1150 LMH bar −1 among the investigated hybrid nanocomposite membranes. In this case, 3D ZIF-8 increased the interlayer spacing within the WS 2 nanolaminate, providing a stable interlayer spacing through coordination bridges between ZIF-8 and WS 2 .…”

“…The incorporation of zeolitic imidazolate frameworks into membrane materials can significantly improve the separation performance, thermal stability, and chemical stability of membranes. [239] In addition, the rapid development of organic solvent nanofiltration technology provides a reliable solution for the poor compatibility of smart nanofiltration membranes under extreme conditions. [240,241] To improve the chemical stability of smart nanofiltration membranes, more stable materials need to be explored.…”

Nanofiltration membrane plays an increasingly important role in many industrial applications, such as water treatment and resource recovery. The performance of the smart nanofiltration membrane is largely controlled by pore size, the Donnan effect, and surface wettability, which are determined by the function of stimuli‐responsive components. Smart membranes, which contain stimuli‐responsive components, are capable of changing their physical and chemical properties in response to changes in the environment so that the microstructure of the membrane will have more efficient performances and broader application prospects than the current traditional nanofiltration membranes. Herein, the preparation methods of stimuli‐responsive membranes are described and they are systematically classified accordingly to their mechanisms. Moreover, the latest progress of stimuli‐responsive membranes in nanofiltration and the main mechanism of each stimuli‐response type through relevant examples are discussed and summarized. Finally, this review provides new insights into the remaining challenges and future directions of stimuli‐responsive membranes. Fueled by advances in chemistry and materials science, it is expected to build a smart and efficient nanofiltration membrane platform for the benefit of mankind.
