摘要:

開發(fā)新型能源是解決全球能源問題的重要手段。鋅-空氣電池有望在能源轉(zhuǎn)化和儲(chǔ)存領(lǐng)域得到廣泛應(yīng)用，但其空氣電極發(fā)生的氧還原反應(yīng)（oxygen reduction reaction，ORR）因反應(yīng)動(dòng)力學(xué)緩慢嚴(yán)重限制了其大規(guī)模應(yīng)用，因此迫切需要開發(fā)高效且穩(wěn)定的ORR催化劑來解決這一問題。鐵元素由于價(jià)格低廉、儲(chǔ)量豐富、獲取方式簡單等優(yōu)點(diǎn)成為ORR催化劑研究的重要選項(xiàng)。近幾年，具有鐵元素相關(guān)活性位點(diǎn)的催化劑受到了廣泛的研究，并被認(rèn)為是最具潛力的貴金屬催化劑的替代品。簡要介紹了可用于ORR的鐵基碳材料催化劑（iron-based carbon material catalyst，IBCMC）的研究現(xiàn)狀，按照活性位點(diǎn)分類分別探討活性位點(diǎn)對IBCMC催化性能的影響，并對影響IBCMC穩(wěn)定性能的因素進(jìn)行了討論，展望了IBCMC在ORR催化領(lǐng)域的發(fā)展方向。

Abstract:

The development of new energy sources is an important approach to solve the global energy problems. Zinc-air battery is expected to be widely used in the field of energy conversion and storage, but the oxygen reduction reaction (ORR) of air electrode severely limits its large-scale application due to sluggish reaction kinetics. Therefore, efficient and stable catalysts are urgently needed to solve this problem. Iron element has become an important alternative for the research of ORR catalysts due to its advantages such as low price, abundant reserves, and simple acquisition methods. In recent years, catalysts with active sites related to iron have been extensively studied and are considered to be the most potential substitutes for precious metal catalysts. In this article, the current research status of iron-based carbon material catalyst (IBCMC) used for ORR are briefly introduced. Based on the clarification of active sites, their effects on the catalytic performance of IBCMC are extensively elaborated. Moreover, the factors affecting the stability of the catalyst are discussed. At last, the future development direction of IBCMC in the field of ORR catalysis is prospected.
