“…Numerous porous materials, such as Vycor glass [ 81 , 82 ], sintered metals [ 71 , 78 , 83 ], a wide variety of ceramics [ 53 , 71 , 84 , 85 ] and even polymers [ 86 , 87 , 88 ], can be used as supporting materials for the H 2 -selective layer. The most relevant attributes of supports to be selected include porosity properties (mainly average porosity and pore sizes distribution), surface roughness and mechanical, chemical and thermal stabilities [ 89 ].…”

In the last years, hydrogen has been considered as a promising energy vector for the oncoming modification of the current energy sector, mainly based on fossil fuels. Hydrogen can be produced from water with no significant pollutant emissions but in the nearest future its production from different hydrocarbon raw materials by thermochemical processes seems to be more feasible. In any case, a mixture of gaseous compounds containing hydrogen is produced, so a further purification step is needed to purify the hydrogen up to required levels accordingly to the final application, i.e., PEM fuel cells. In this mean, membrane technology is one of the available separation options, providing an efficient solution at reasonable cost. Particularly, dense palladium-based membranes have been proposed as an ideal chance in hydrogen purification due to the nearly complete hydrogen selectivity (ideally 100%), high thermal stability and mechanical resistance. Moreover, these membranes can be used in a membrane reactor, offering the possibility to combine both the chemical reaction for hydrogen production and the purification step in a unique device. There are many papers in the literature regarding the preparation of Pd-based membranes, trying to improve the properties of these materials in terms of permeability, thermal and mechanical resistance, poisoning and cost-efficiency. In this review, the most relevant advances in the preparation of supported Pd-based membranes for hydrogen production in recent years are presented. The work is mainly focused in the incorporation of the hydrogen selective layer (palladium or palladium-based alloy) by the electroless plating, since it is one of the most promising alternatives for a real industrial application of these membranes. The information is organized in different sections including: (i) a general introduction; (ii) raw commercial and modified membrane supports; (iii) metal deposition insights by electroless-plating; (iv) trends in preparation of Pd-based alloys, and, finally; (v) some essential concluding remarks in addition to futures perspectives.

He graduated with a Ph.D. from the Technical University of Eindhoven in 2005 within the field of process development and started at SINTEF shortly thereafter. His research interests span from process chemistry, membrane technology, hydrogen production, CO2 capture, and energy efficiency, to gas separation technologies. He has 54 publications in international peer-reviewed journals (h-index = 21) and has contributed to 10 book chapters and >150 conferences. Alessio Caravella is currently Associate Professor chairing the courses of Thermodynamics and Chemical Reactors Design at the Dept. of Environmental and Chemical Engineering (DIATIC) of the University of Calabria (Italy), as well as Associate Researcher at the Institute on Membrane Technology (ITM-CNR, Italy). His main research activities focus on the experimental analysis and simulation of hierarchical catalytic structures and membrane-assisted reaction and separation devices, with a particular regard to the application of Pd-based membranes devices to hydrogen purification. Recently, he is also investigating the adsorption properties of zeolites and coordination polymer particles for hydrogen separation from light gases. vii
