范曉雷，英國(guó)曼徹斯特大學(xué) (The University of Manchester) 化學(xué)工程系教授，博士生導(dǎo)師。范曉雷博士2010年畢業(yè)于英國(guó)巴斯大學(xué) (University of Bath)，獲得化學(xué)工程博士學(xué)位，先后在英國(guó)華威大學(xué) (University of Warwick) 及劍橋大學(xué)(University of Cambridge) 從事博士后研究工作，2013年就職于曼徹斯特大學(xué)。范曉雷博士的研究領(lǐng)域主要為多相催化、結(jié)構(gòu)型催化劑、化工過程強(qiáng)化、低溫等離子體催化及新型多孔材料的基礎(chǔ)研究及其在化學(xué)化工領(lǐng)域的應(yīng)用。迄今，累計(jì)在Nature Catalysis, Angewandte Chemie, Applied Catalysis B, AIChE Journal, Chemical Engineering Science, Industrial & Engineering Chemistry Research等化工專業(yè)期刊發(fā)表論文70余篇，參與撰寫學(xué)術(shù)專著1部，申請(qǐng)國(guó)際發(fā)明專利1項(xiàng)。范曉雷博士課題組現(xiàn)有博士和博士后16人，獲得英國(guó)工程與自然科學(xué)研究委員會(huì) (EPSRC)、英國(guó)皇家學(xué)會(huì) (The Royal Society)、歐盟 (EC)等資助科，科研經(jīng)費(fèi)約為150萬英鎊。其于2018年獲得中國(guó)科學(xué)院金屬研究所的李薰青年學(xué)者講座獎(jiǎng)，2019年被選為旅英中國(guó)學(xué)人化學(xué)科學(xué)與技術(shù)學(xué)會(huì)會(huì)長(zhǎng)。
主要內(nèi)容：
Synthetic zeolites are class of porous crystalline aluminosilicate materials with intrinsic pore sizes of <1 nm, being the most important yet practical porous materials in chemical industry. They have been used as solid acid catalysts for many industrial catalytic applications, especially petrochemical industries such as fluidised catalytic cracking (FCC), hydrocracking, hydrocarbon isomerisation and alkylation. However, their intrinsic micropores can cause accessibility/diffusion issues, which reduce the efficiency of their uses in catalysis and cause the catalyst deactivation. The introduction of secondary mesopores (2-50 nm) into the zeolites’ frameworks can help to address the accessibility/diffusion issues, and it can be achieved practically by the post-synthetic treatment methods such as dealumination and desilication. In this seminar, the recent development of new post-synthetic treatment methods in Fan’s group for making mesoporous FAU Y zeolites and mesoporous MFI ZSM-5 nanoboxes (with a very low silicon to aluminum ratio) will be presented, highlighting the novelty of these newly developed methods and the significance of the developed zeolites in catalysis.
