Manipulating Copper Dispersion on Ceria for Enhanced Catalysis: A Nanocrystal‐Based Atom‐Trapping Strategy
Yifan Sun,Felipe Polo-Garzon,Zhen Bao,Jisue Moon,Zhennan Huang,Hao Chen,Zitao Chen,Zhenzhen Yang,Miaofang Chi,Zili Wu,Jue Liu,Sheng Dai +11 more
TL;DR: A nanocrystal-based atom-trapping strategy to access atomically precise Cu-CeO2 nanostructures for enhanced catalysis is reported and facilitates tuning of the copper dispersion and the associated creation of surface oxygen defects on CeO2, which gives rise to enhanced activities and stabilities catalyzing water-gas shift reaction.
Journal ArticleDOI
Multiple Promotional Effects of Vanadium Oxide on Boron Nitride for Oxidative Dehydrogenation of Propane
Xiao Jiang,Xuanyu Zhang,Stephen C. Purdy,Yang He,Zhennan Huang,Rui-Wei You,Zeyue Wei,Harry M. Meyer,Jiuzhong Yang,Yang Pan,Peiwen Wu,Wenshuai Zhu,Miaofang Chi,Katharine Page,Weixin Huang,Zili Wu +15 more
TL;DR: In this article , vanadium oxide dispersion onto hexagonal boron nitride (h-BN) facilitates the oxyfunctionalization of BN to generate more BOx active sites to catalyze ODHP via the Eley-Rideal mechanism and concurrently produce nitric oxide to initiate additional gas-phase radical chemistry.
