摘 要: 氫能作為一種清潔、高能、無二次污染的“綠色能源”，被認(rèn)為是后石油時代解決能源危機(jī)和環(huán)境危機(jī)的理想能源之一。其中電解水析氫技術(shù)因反應(yīng)高效、易控、無污染等特點(diǎn)而逐漸成為研究熱點(diǎn)。目前析氫性能最好的催化劑依然是Pt基催化劑。然而Pt儲量少、價格貴，無法滿足大規(guī)模氫氣生產(chǎn)的現(xiàn)實(shí)需求。因此，如何進(jìn)一步提高現(xiàn)有非Pt催化劑的析氫性能或開發(fā)廉價高效的新型催化劑是實(shí)現(xiàn)電解水析氫規(guī)模化生產(chǎn)的關(guān)鍵。結(jié)合本課題組在電解水方面的研究工作，綜述近幾年非Pt析氫催化劑的研究新進(jìn)展，重點(diǎn)介紹新型過渡金屬化合物催化材料的結(jié)構(gòu)設(shè)計與調(diào)控對析氫性能的影響，并對電解水析氫催化劑面臨的挑戰(zhàn)及發(fā)展方向進(jìn)行展望。

Abstract:Hydrogen energy is a clean, high energy, environmentally friendly resource which is considered as one of the most promising candidates for replacing fossil fuels in the future. Electrochemically splitting water into hydrogen by renewable energy has attracted much attention due to its high efficiency, easy operation and no secondary pollution. Although the state-of-the-art catalyst for HER is a typical Pt-based catalyst, its scarcity and high cost prevent their widespread applications. Thus, it is highly desirable to exploit non-Pt HER catalysts with high activity, long-term stability and low cost. The recent advancements in the area of non-Pt HER catalysts with emphasis on introducing the exciting new research in the structure regulation of transition metal compounds and the understanding of the mechanisms of catalysts were reviewed. Meanwhile, the insights into the remaining challenges and research directions were proposed to shed light on future development of non-Pt HER catalysts.
Key words: water electrolysis; hydrogen energy; hydrogen evolution reaction; non-Pt catalyst
