- Аннотация: BaZr0.7Ce0.2Y0.1O3-δ (BZCY) is a widely investigated protonic ceramic material, which can be fabricated into gas-tight membrane for hydrogen separation. However, the insufficient hydrogen permeation flux represents a critical limitation for its practical deployment. In this study, we successfully prepared a BZCY four-channel hollow fiber membrane through one-step thermal processing method, demonstrating a peak hydrogen permeation flux of 0.83 mL min−1 cm−2 at 900°C. Building upon this membrane, a membrane reactor was developed for reverse water–gas shift (RWGS) reactions. The RWGS membrane reactor demonstrated remarkable performance, achieving an experimental CO2 conversion of 52.1 % which closely approaches the theoretical limit of 52.6 %. Additionally, the RWGS membrane reactor exhibited exceptional flexibility in H2/CO ratio, with tunable ratios spanning from 0.20 to 1.12, providing significant operational adaptability to meet diverse industrial demands. These advancements substantially enhance the prospects for implementing protonic ceramic membranes in hydrogen separation processes and membrane reactor technologies.
