PrefacetoSpecialIssueofChineseJournalofCatalysisinMemoryofProfessorQinXin

This special issue is dedicated to Professor Qin Xin on the occasion of one year of his passing away. This is in recognition of his unique and remarkable contributions to the application of in-situ molecular spectroscopy for catalysis study, the exploration of nitrides, carbides and HDS(hydrodesulfurization), HDN (hydrodenitrogenation) catalysts, and the development of efficient electrocatalysts for direct alcohol fuel cells.Professor Xin was born in Harbin in April 1939. After graduating from the Department of Chemistry, Jilin University in 1962, he worked in Dalian Institute of Chemical Physics (DICP), Chinese Academy of Sciences (CAS) as an assistant, associate, senior, distinguished, and emeritus researcher, until he suddenly passed away in June 2020.
