Highly sulfur-tolerant Pd composite membranes with a protective layer of MoS2/γ-alumina

Sulfur-tolerant Pd-based composite membranes were produced by coating a thin layer of MoS2/γ-alumina on the membrane surface. This layer acted as an “armor” to prevent H2S from directly contacting the Pd membrane surface by preferentially adsorbing and decomposing the H2S.
