Abstract

Biochar has been prepared by pyrolysis of (the vegetable sponge produced by ) and activated by mixing the pyrolyzed powder with KOH and pyrolyzed again. Non-activated and activated biochar have both been structurally and then electrochemically characterized to record their differences and assess their suitability as bifunctional oxygen reduction and oxygen evolution reaction electrocatalysts in Zn-air batteries. Non activated biochar carries several functional groups; however, the activation procedure led to a material with mainly O and Mg groups. Biochar activation improved its electrocatalytic properties, but both activated and non-activated luffa biochar were functional as bifunctional electrocatalysts to a satisfactory degree. This is justified by the fact that both carried a large percentage of carbon and graphitic carbon. The advantage of the non-activated biochar the activated biochar was its variety of functional groups while that of the activated biochar was its large specific surface area.

摘要

生物炭通过对（所产生的植物海绵）进行热解制备，并通过将热解粉末与KOH混合并再次热解来活化。已对未活化和活化的生物炭进行了结构和电化学表征，以记录它们的差异，并评估它们作为锌空气电池中双功能氧还原和析氧反应电催化剂的适用性。未活化的生物炭带有几个官能团；然而，活化过程产生了一种主要含有O和Mg基团的材料。生物炭活化改善了其电催化性能，但活化和未活化的丝瓜生物炭作为双功能电催化剂都具有令人满意的功能。这是因为两者都含有大量的碳和石墨碳。未活化生物炭相对于活化生物炭的优势在于其官能团种类多样，而活化生物炭的优势在于其较大的比表面积。
