Since hydrogen.storage alloy ean not only absorb hydrogen atoms to form highlyreactive metal hydride as hydrogen source by electrolysis but also possesses a certain catalytic activityfor hydrogenation,it is thus feasible to utilize the allov as a novel electrOde for electrolvtichydrogenation in organic electrored uction. This work employed misch metal AB_5 type alloy as acatalytic electrode and studied the electrochemical hydrogenation of nitrobenzene. The hydrogen-storage electrede(MH)was a plastic bonded electrede sheet made from a paste ofMm(NiCoMnAl)_5 alloy powder and teflon emulsion. The electrolysis was performed at constantcurrent and controlled potential in a three electrede cell of H-type configuration. The electrolyte was0.5 …
