The results indicated that the self-made Pd/C gas-diffusion cathode can not only reductively dechlorinate 2,4-dichlorophenols by feeding hydrogen gas, but also accelerate the two-electron reduction of O2 to hydrogen peroxide (H2O2) by feeding air.
Even during the time intervals when flies fed hydrogen peroxide were less active than controls, based on distance moved per hour, their behavior was abnormal, in that movement was more erratic (greater heading changes) than a control fly moving at a comparable speed (Table 2B; Figure 2D).
However, when flies were continuously fed hydrogen peroxide, activity was initially increased, and then after about 12 hours the daily locomotor rhythms became suppressed: flies were more active than controls during the sleep periods, and less active than controls during the wake periods (Figure 2B,C).
