The feasibility of using Sn-doped Al-Ni alloy powder as low-cost cathode catalyst for H2 production in microbial electrolysis cells (MEC)was studied.The synergism of Ni
Al and Sn could improve the hydrogen selectivity of catalyst.SEM photographs showed that Ni-Al-Sn alloy powders had a single morphology when the content of Sn was 0
5%
10%
while two different appearances could be found when the content of Sn was 15%.XRD patterns indicated that only Ni-Al-Sn alloy phase could be detected in 0
5%
10% Sn-doped Ni-Al alloy powders
while Sn could be detected besides the alloy phase for 15% Sn-doped Ni-Al alloy powders.Compared with platinum catalyst
although the alloy catalyst produced more slowly hydrogen gas
it had higher selectivity of hydrogen.The catalyst containing 50% Ni
45% Al
5% Sn was the better catalyst for H2 production from MEC.MEC could replace the anaerobic system and produce hydrogen in the process of wastewater treatment.
