(a) Effects of pH on the Ptn/gDNA–GO composite. The pH value is numbered on each bottle. The Ptn/gDNA–GO composite was placed into the respective solutions, and allowed to stand at room temperature for 8 weeks. (b) The relative mass activity of the catalysts measured in O2-saturated electrolytes of varying pH with a scan rate of 10 mV s−1 at a rotation speed of 1,600 r.p.m.
