In this paper, the deposition of Ag porous foams from a novel electrolyte, using hydrogen bubbles as a template during deposition at high cathodic currents, is described. Using NH4+ to increase the hydrogen evolution rate, foams with an average pore

Anodization of niobium in mixed H2SO4/HF electrolytes was investigated. Under optimized electrochemical conditions the formation of self-organized porous Nb2O5 layers was observed. The porous Nb2O5 layers consist of ordered pore arrays with single po
