Abstract: A method for producing a metal structure comprising a porous inter-dendritic matrix defining a network of dendritic channels, the method comprising the steps of: preparing an alloy melt comprising a metal element and at least one alloying element, cooling the alloy melt to a solid alloy, wherein the cooling promotes formation of a network of dendrites rich in the at least one alloying element within an inter-dendritic matrix rich in the metal, dealloying the solid alloy to remove alloying element from the dendrites and the inter-dendritic matrix to obtain the metal structure.
