Effect of different substrate types on power and current production. (a) Maximum surface power density of nickel silicide nanowires on foam at various flow rates using glucose as the microbial substrate. (b) Surface power density and polarization curve of nickel silicide nanowires on foam at the optimal glucose flow rate (2 µL min-1). (c) Maximum surface power density of nickel silicide nanowires on foam at various flow rates using urea as the microbial substrate. (d) Surface power density and polarization curve of nickel silicide nanowires on foam at the optimal urea flow rate (4 µL min-1). (e) Comparison of the maximum surface power density of nickel foam versus nickel silicide nanowires on foam with different feeding substrates.
