These applications require a high membrane surface area and packing density to achieve high efficiency. Hollow fiber membrane configurations offer such high packing densities and thus significantly enhance the membrane module performance. However, regulating the pore size of metal hollow fiber membranes remains challenging. In this study, the pore size of fabricated nickel (Ni) hollow fiber membranes (NHFMs) was tuned under redox conditions. The influence of the oxidation–reduction temperature on pore morphology and separation performance was systematically investigated. Optimized redox conditions yielded NHFMs with a narrow pore size distribution (mean pore size ∼60 nm, maximum ≤70 nm) and high porosity (∼47%), achieving a N₂ permeance of 2.7 × 10⁴ GPU. Additionally, the pore size of NHFMs was tuned to a mean pore size of 162–177 nm, which demonstrated excellent bovine serum albumin (BSA) separation, exhibiting a 96.6% rejection rate and a water flux of 71 L/(m²·h).

The catalytic performance was tested in the transfer hydrogenation of cinnamaldehyde (CAL) to selectively produce cinnamyl alcohol (COL). The catalyst with a Mg/Al ratio of 3 (Mg₃–Al₁@C) exhibited 97.2% conversion with 99.9% selectivity to COL in 3 h at 100 °C using isopropanol (IPA) as the solvent and hydrogen donor, and, in contrast, the counterpart without carbon coating (Mg₃–Al₁) gave 50.3% conversion with 88.2% selectivity. Characterization by means of X-ray diffraction (XRD), CO₂-TPD, NH₃-TPD, and transmission electron microscopy (TEM) revealed that the carbon layer on Mg–Al mixed metal oxide was able to markedly reduce the undesired sites of strong acid and strong base. It was found that the improved selectivity to COL was related to the reduction of the strong basic sites on the surface, which promoted the side reaction of aldol condensation of cinnamaldehyde. The adsorption of IPA, CAL, and COL, as well as the measurements of contact angle, revealed that the high performance of Mg₃–Al₁@C was closely related to the enhanced desorption of COL and improved adsorption of both IPA and CAL due to the presence of the external carbon layers. In addition, the presence of carbon layers helps to prevent the unfavorable deposition of bulky molecules produced in the course of the reaction. After seven consecutive runs, the conversion and selectivity of Mg₃–Al₁@C hardly changed, whereas those of Mg₃–Al₁ declined from 43.3% to 3.9%.

Alcohol-aminolysis with ethanolamine can convert PC waste back into its monomer bisphenol A (BPA) and the valuable product 2-oxazolidinone. However, the use of hazardous solvents complicates both the recovery of PC and the synthesis and separation of 2-oxazolidinone. Herein, we developed a sustainable alcohol-aminolysis strategy utilizing the eco-friendly solvent ethanol (EtOH), achieving yields of 93% BPA and 88% 2-oxazolidinone from compact discs in 4 h at 80 °C. Multilinear regression revealed that elevated Kamlet–Taft parameters (β, π*) correlate strongly with enhanced PC alcohol-aminolysis efficiency for most solvents. Conversely, in monohydric alcohols, reactivity exhibits minimal dependence on β- and π*-values but is primarily governed by their steric hindrance. Mechanistic investigation reveals that EtOH enhances the nucleophilicity of ethanolamine, enabling nucleophilic attack on the activated carbonyl group of PC while facilitating cyclization of the intermediate. In gram-scale experiments, we recovered 8.64 g of BPA and 2.96 g of 2-oxazolidinone from 10.16 g of PC using simple filtration and evaporation.
