Pilot-scale synthesis of multi-channel ceramic catalytic membranes

Catalytic membranes lack industrial application due to limited pilot-scale synthesis knowledge. Here, we report the first successful fabrication of 22 cm cobalt-based multi-channel ceramic catalytic membranes. Precursor flow rate was identified as key to control Co nanoparticle distribution and performance. Optimized Co0.18@CM-550 achieved full p-nitrophenol hydrogenation in 4.5 min and remained stable for 50 h under elevated process capacity. Excellent batch-to-batch repeatability across 20 runs provides critical insights for scalable catalytic membrane production and application.
