“…It is well known that the wastewater contains many kinds of magnetic substances, for example, Fe, Co, Ni, and their oxides 43 . Compared with the powder supports, the thin‐film supports (Scheme S1③) including the PAN‐Si membrane, 44 Cu foil, 45 PVDF membrane, 46 glass, 47 and cellulose paper, 48 and so on, are undoubtedly easier to recycle, but their lower specific surface area reduces the catalytically active sites of metal nanoparticles. Although the porous supports (Scheme S1④), for example, lignocellulose hydrogel, 49 Cu foam, 50 and TiO 2 scaffold 51 have higher active area than the thin‐film supports, most of their activity and stability are still far below expectations.…”

An amorphous Ni nanoparticles-loaded ZnO nanowire array is controllably constructed on stainless steel mesh through combined electrodeposition and hydrothermal reaction. Its nano-arrayed structure not only provides a platform to achieve stable and good dispersion of Ni nanoparticles, but also helps improve their ability to adsorb 4-nitrophenolate ions and to capture hydrogen radicals, thereby accelerating the hydrogen transfer from metal hydride complex to 4-nitrophenol. Benefiting from the abovementioned unique features, it outperforms most Ni-based catalysts. While a 30-s re-electrodeposition of Ni can provide it extra 150 min of high catalytic activity towards the reduction of waste 4-nitrophenol to valuable 4-aminophenol, further demonstrating its outstanding reusability. The highly general methodology reported here paves the way to economically and effectively synthesize various other metal nanoparticles-loaded ZnO nanowire arrays on different conductive substrates, which not only enrich the nanowire-arrayed catalysts, but also significantly promote their practical utilizations in a wide range of environment-related fields.

“…Most of the organic dyes and their intermediates are carcinogenic and easily soluble in water [1]. Very low concentration in water can alter the color, thus changing the refraction index of water, which is not only caused the visual pollution but also interfered with the absorb sunlight of aquatic life [2][3][4][5]. To solve this problem, a variety of approaches have been developed to remove these pollutants, including physical adsorption [6,7], chemical and biological methods [8].…”

“…The membrane is the carrier of a catalyst. The catalytically active components are deposited on the membrane by many methods such as impregnation, ion exchange, and sputtering. − Under the action of a pump, the reactants A and B are forced to pass through the catalytic membrane P. The flow rate of the reactants is changed to adjust the contact time between the reactants and the catalyst, which eliminates the influence of the mass-transfer limitations caused by pore diffusion on the macroscopic reaction rate, thereby generating products C and D.…”

“…The design and preparation of high-performance catalytic membranes are key for contactor-type membrane reactors. − Compared with suspended catalysts, the largest limitation of catalytic membranes is the low content of active components per unit volume of the membrane, which limits the practical application of catalytic membranes. Therefore, determining how to increase the loading of active components in catalytic membranes and improve the catalytic efficiency of the active components have become a popular research topic of catalytic membranes. , In recent years, researchers have mainly conducted research on the membrane configuration, , preparation methods, and membrane surface modification , to increase the loading of active components, strengthen the binding between the active components and the membrane, and improve the uniformity of active components on the membrane, thereby improving the catalytic efficiency of the catalytic membrane.…”

Reaction and separation are the core of chemical and petrochemical production processes. The problems of resource and energy waste and environmental pollution caused by the low efficiency of reaction and separation have become increasingly prominent and have been the bottlenecks, with regard to sustainable development of the industry. The development of membrane reactor technology to achieve efficient conversion and separation has become an important research direction. In this Review, porous membrane reactors are divided into three types: contactor, distributor, and extractor types, based on the function of the membrane. The latest research progress of our group in liquid-phase catalytic reactions and the research status in this field are reviewed. For the contactor-type membrane reactor, the design and preparation of the catalytic membrane are discussed from three aspects: membrane configuration, preparation method, and membrane surface modification. For the distributor-type membrane reactor, the focus is on the influences of the membrane microstructure and operating parameters on the droplet/bubble formation and mass transfer, as well as the application of distributor-type membrane reactors. For the extractor-type membrane reactor, after the configuration of the membrane reactor is introduced, the research progress of extractor-type membrane reactors for liquid-phase catalytic reactions is discussed from two aspects: the synergistic control of the catalysis and membrane separation processes, and the mechanism and control of membrane fouling. The industrialization of extractor-type membrane reactors is described. Finally, the future challenges and development directions of porous membrane reactors applied to liquid-phase catalytic reactions are discussed.
