More specifically, we optimized the titration time required to obtain highly active CeO2-supported catalysts for the WGS reaction. As such, Cu was employed as the active metal coupled with the CeO2 support. Notably, the CeO2-0 supported Cu catalyst (where the precipitant was immediately injected into a cerium nitrate solution) exhibited the highest CO conversion at a gas hourly space velocity of 36,050 h(-1). This high catalytic activity of the Cu/CeO2-0 catalyst was mainly due to its high Brunauer-Emmett-Teller (BET) surface area, enhanced Cu dispersion, high number of oxygen vacancies, and enhanced reducibility.1 aNa, Hyun-Suk1 aShim, Jae-Oh1 aJang, Won-Jun1 aJeon, Kyung-Won1 aKim, Hak-Min1 aLee, Yeol-Lim1 aLee, Da-We1 aYoo, Seong-Yeun1 aBae, Jong, Wook1 aRode, Chandrashekhar, V.1 aRoh, Hyun-Seog  uhttps://library.ncl.res.in/content/effect-titration-time-catalytic-performance-cuceo2-catalysts-water-gas-shift-reaction
