Preparation of Nanostructured Microporous Metal Foams through Flow Induced Electroless Deposition

Figure 15

Inner bulk structures of the monoliths showing the effect of reducing agent concentration. Experimental conditions: [Ni] = 0.13 M; °C, °C/min;  min followed by cooling in air. (a) General appearance of the bulk structure showing the presence of pore hierarchy with large arterial pores (interconnects/windows) with size range 10–30 μm and pore walls made from the porous capillaric structures of ca. 10 μm size. Reducing agent concentration [P] = 0.63 M, scale bar = 50 μm. (b) Sample as in Figure 15(a) at larger magnification. Scale bar = 10 μm. (c) Reducing agent concentration [P] = 1.26 M. Scale bar = 10 μm. (d) Reducing agent concentration [P] = 2.52 M. Scale bar = 10 μm.
