“…Meanwhile, inorganic hollow fiber membranes such as carbon-based and ceramic-based are extensively reported and focus on H 2 , O 2 , and CO 2 separation. Recent works also include zeolites [ 526 , 527 ], alumina [ 528 ], and MXene [ 201 ] hollow fiber membranes for gas and vapor separation. CMS hollow fiber membranes are temperature- and pressure-resistant materials with a rigid pore structure that are suitable for natural gas sweetening and H 2 purification processes in steam methane reforming plants.…”

The aggravation of environmental problems such as water scarcity and air pollution has called upon the need for a sustainable solution globally. Membrane technology, owing to its simplicity, sustainability, and cost-effectiveness, has emerged as one of the favorable technologies for water and air purification. Among all of the membrane configurations, hollow fiber membranes hold promise due to their outstanding packing density and ease of module assembly. Herein, this review systematically outlines the fundamentals of hollow fiber membranes, which comprise the structural analyses and phase inversion mechanism. Furthermore, illustrations of the latest advances in the fabrication of organic, inorganic, and composite hollow fiber membranes are presented. Key findings on the utilization of hollow fiber membranes in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), pervaporation, gas and vapor separation, membrane distillation, and membrane contactor are also reported. Moreover, the applications in nuclear waste treatment and biomedical fields such as hemodialysis and drug delivery are emphasized. Subsequently, the emerging R&D areas, precisely on green fabrication and modification techniques as well as sustainable materials for hollow fiber membranes, are highlighted. Last but not least, this review offers invigorating perspectives on the future directions for the design of next-generation hollow fiber membranes for various applications. As such, the comprehensive and critical insights gained in this review are anticipated to provide a new research doorway to stimulate the future development and optimization of hollow fiber membranes.

“…Mixed ionic-electronic conducting material (MIEC) is a combination of various metal salts that have great chemical compatibility among themselves. An MIEC cathode choice that is commonly applied in intermediate temperature SOFCs is LSCF due to its excellent ionic and electronic conductivities, which are capable of expanding the active sites from the triple boundary phase to the entire cathode surface [10][11][12]. Currently, conventional LSCF has to be calcined at a high temperature (about 1000 °C) to get good adhesion to the electrolyte in an intermediate temperature range.…”

Infiltration of copper oxide towards LSCF was done in order to enhance cathode performance due to superior properties, including high electrical conductivity and high catalytic activity for the oxygen reduction reaction. Samples were synthesized at different temperatures using the sol-gel route. The TGA results showed that LSCF achieved complete perovskite formation when calcined above 600 °C and DTA showed the formation of lattice oxygen at 550 °C. XRD analysis showed no shifted peaks and nano size levels were achieved when samples were calcined at 700 °C and 800 °C. SEM and BET showed similar analysis patterns, where the particle size increased as the calcining temperature was increased. EIS analysis further verified that the polarization resistance of the sample calcined at 700 °C was as small as 0.161 Ω, compared to 1.524 Ω with a calcination temperature of 800 °C. The activation energy of LSCF-CuO was found to be 122.2 kJ/mol, which is much lower than for conventional LSCF.

Effect of Vesicle Structure on Catalytic Activity of Suzuki‐Miyaura Cross‐Coupling Reaction: Impact of Framework and Morphology

2020

A novel hybrid porous polymer with hollow vesicle structure has been synthesized via Friedel-Crafts alkylation reaction and solvent-induced method. The resulting two-dimensional networks are hierarchical porous materials with high Brunauer-Emmett-Teller (BET) surface area of 1582 m 2 g À 1. The vesicle structure directly influenced the activity and shaping the performance of the catalyst. The kinetic study reveals the special vesicle structure can enrich the substrates in a limit scope and increase the reaction rate. It has been demonstrated that the framework and morphology play a major role on the catalysts' excellent performance in Suzuki-Miyaura cross-coupling reaction of aryl chlorides. These findings help elucidate the mode action of the vesicle structure in the unrevealed Suzuki reaction mechanism of supports and the potential development of new morphology control catalysts.
