Thermodynamically driven self-formation of copper-embedded nitrogen-doped carbon nanofiber catalysts for a cascade electroreduction of carbon dioxide to ethylene
Autor: Sang‐Ho Oh, Jihun Oh, Young-Chang Joo, Deokgi Hong, Wonhyo Joo, Ji-Yong Kim, Jae-Chan Lee, Gun-Do Lee, Beomil Kim, Miyoung Kim
Publikováno v: Journal of Materials Chemistry A. 8:11632-11641
Electrocatalysts for CO2 electroreduction require not only high-performance active materials to control the series reaction but also conductive and durable supports to ensure long-term stability under harsh operating conditions. Instead of convention

Mechanistic origin of the time-dependence of the open-circuit voltage of a galvanic cell involving a ternary or higher compound
Autor: Manfred Martin, Jihye Kim, Wonhyo Joo, Han-Ill Yoo
Publikováno v: Physical chemistry chemical physics : PCCP. 23(28)
It has previously been predicted [H.-I. Yoo and M. Martin, Phys. Chem. Chem. Phys., 2010, 12, 14699] and observed [E. Kim, et al., Solid State Ionics, 2013, 235, 22] that the open-circuit voltage U of a galvanic cell, involving a ternary or higher co

Synthetic Mechanism Discovery of Monophase Cuprous Oxide for Record High Photoelectrochemical Conversion of CO2 to Methanol in Water
Autor: Hyung Ho Kim, Ki Tae Nam, Young-Chang Joo, Dae-Hyun Nam, Seong-Hyeon Hong, Hoyoung Kwak, Ho-Young Kang, Ki Dong Yang, Wonhyo Joo
Publikováno v: ACS Nano. 12:8187-8196
Precise control of the oxidation state of transition-metal oxides, such as copper, is important for high selectivity of CO2 reduction in an aqueous condition to compete with the reduction of water. The phase of copper oxide nanofibers was controlled

Point defect structure of γ-NaxCoO2
Autor: Han-Ill Yoo, Wonhyo Joo
Publikováno v: Solid State Ionics. 314:74-80
Oxygen nonstoichiometry and electrical conductivity were measured on the system of γ-NaxCoO2, allegedly so far the best p-type thermoelectric oxide, against oxygen activity (aO2) across its widest ever range below aO2 = 1 for a fixed Na-content x =

Publikováno v: Nano letters. 19(12)
Controlled phase conversion in polymorphic transition metal dichalcogenides (TMDs) provides a new synthetic route for realizing tunable nanomaterials. Most conversion methods from the stable 2H to metastable 1T phase are limited to kinetically slow c
