二氧化鈰與氫氣之間相互作用及其在炔烴選擇加氫中的應(yīng)用(英文)
發(fā)布時(shí)間:2021-12-29 06:59
二氧化鈰因其具有較強(qiáng)的氧化還原性能和多變的酸堿功能而在催化領(lǐng)域有著廣泛的應(yīng)用,其可用作催化劑、改性劑或載體.雖然二氧化鈰常被用于氧化反應(yīng),但由于其獨(dú)特的選擇性地將炔烴加氫成烯烴的能力,近年來(lái)引起了廣泛的研究興趣.氧化鈰出色的加氫能力引發(fā)了新的研究熱潮,以了解純二氧化鈰用作加氫催化劑的原理.本文綜述了近年來(lái)氧化鈰的實(shí)驗(yàn)和計(jì)算研究進(jìn)展,重點(diǎn)介紹了氧化鈰與氫氣的相互作用和加氫反應(yīng).討論了各種研究的重要觀點(diǎn),包括原位光譜/顯微鏡和鈰在涉氫反應(yīng)中的理論模型,從而闡明了氧化鈰催化炔烴加氫反應(yīng)能力的本質(zhì)和反應(yīng)機(jī)理.最后在總結(jié)和展望部分提出了進(jìn)一步提高對(duì)鈰基材料加氫反應(yīng)機(jī)理認(rèn)識(shí)和催化性能的途徑.
