Denis Johnson,Abdoulaye Djire +1 more
TL;DR: In this article , the effect of pH on NRR performance was investigated and the results indicated that the lowest NRR onset occurs within pH 2 systems exhibiting a nonlinear trend, however, as pH decreases, overpotential decreases, and kinetics increase due to H+ participation.
