Asymmetric nickel hollow fibres as the catalytic membrane reactor for CO2 hydrogenation into syngas†
Abstract
Herein, we report the development of highly asymmetric Ni hollow fibres with a dense skin layer integrated on a porous substrate by a single-step spinning and sintering technique. Such hollow fibers display outstanding performance for H2 separation and excellent catalytic activity, and can directly serve as a catalytic membrane reactor for CO2 hydrogenation into syngas.
