“…22 The fabricated Pd composite on a tubular stainless steel support via the electroless plating method displayed an H 2 permeance of 2.26 × 10 −3 mol m 2 s −1 Pa −0. 73 The zeolite layer protected the Pd bulk from harmful species, and silanization increased hydrophobicity on the TS-1/Pd composite membrane by lowering hydroxyl density. The TS-1/Pd membrane had 0.95% carbon content after 100 h of steam reforming, compared to 13.20% for the pure Pd membrane.…”

Keeping global warming at 2 degrees and below as stated in the "Paris Climate Agreement" and minimizing emissions can only be achieved by establishing a hydrogen (H 2 ) ecosystem. Therefore, H 2 technologies stand out in terms of accomplishing zero net emissions. Although H 2 is the most abundant element in the known universe, molecular H 2 is very rare in nature and must be produced. In H 2 production, reforming natural gas and renewable hydrogen processes using electrolyzers comes to the fore. The key to all these technologies is to enhance production speed, performance, and system lifetime. At this point, composite membranes used in both processes come to the fore. This review article summarizes composite membrane technologies used in methane, ethanol, and biomass steam reforming processes, proton exchange membranes, alkaline water electrolysis, and hybrid sulfur cycle. In addition to these common H 2 production technologies at large quantities, the innovative systems developed with solar energy integration for H 2 generation were linked to composite membrane utilization. This study aimed to draw attention to the importance of composite membranes in H 2 production. It aims to prepare a guiding summary for those working on membranes by combining the latest and cutting-edge studies on this subject.

“…This leads to a lattice distortion, the formation of high internal stresses, deformation, and, ultimately, membrane destruction [ 19 ]. In addition to embrittlement, palladium is quite susceptible to poisoning and surface contamination by impurity gases, that contain sulfur or carbon compounds [ 20 , 21 , 22 ]. In addition, a significant difficulty in the fabrication of membranes based on pure palladium is the high metal cost [ 23 , 24 ].…”

Thin Pd–40%Cu films were obtained via the classical melting and rolling method, magnetron sputtering, and modified with nanostructured functional coatings to intensify the process of hydrogen transportation. The films were modified by electrodeposition, according to the classical method of obtaining palladium black and “Pd–Au nanoflowers” with spherical and pentagonal particles, respectively. The experiment results demonstrated the highest catalytic activity (89.47 mA cm−2), good resistance to CO poisoning and long-term stability of Pd–40%Cu films with a pentagonal structured coating. The investigation of the developed membranes in the hydrogen transport processes in the temperature range of 25–300 °C also demonstrated high and stable fluxes of up to 475.28 mmol s−1 m−2 (deposited membranes) and 59.41 mmol s−1 m−2 (dense metal membranes), which were up to 1.5 higher, compared with membrane materials with classic niello. For all-metal modified membranes, the increase in flux was up to sevenfold, compared with a smooth membrane made of pure palladium, and for deposited films, this difference was manyfold. The membrane materials’ selectivity was also high, up to 4419. The developed strategy for modifying membrane materials with functional coatings of a fundamentally new complex geometry can shed new light on the development and fabrication of durable and highly selective palladium-based membranes for gas steam reformers.
