The Bell-Evans-Polanyi relation for hydrogen evolution reaction from first-principles

Publikováno v: npj Computational Materials, Vol 10, Iss 1, Pp 1-6 (2024)

Abstract The versatile Bell-Evans-Polanyi (BEP) relation stipulates the kinetics of a reaction in terms of thermodynamics. Herein, we establish the BEP relation for the hydrogen evolution reaction (HER) from fundamental electrochemical principles lev

Autor: Tarak Nandi, Leebyn Chong, Jongwoo Park, Wissam A. Saidi, Benjamin Chorpening, Samuel Bayham, Yuhua Duan

Publikováno v: AIP Advances, Vol 14, Iss 3, Pp 035231-035231-10 (2024)

To evaluate the high temperature sensing properties of metal oxide and perovskite materials suitable for use in combustion environments, it is necessary to understand the temperature dependence of their bandgaps. Although such temperature-driven chan

Designing multinary noble metal‐free catalyst for hydrogen evolution reaction

Autor: Wissam A. Saidi, Tarak Nandi, Timothy Yang

Publikováno v: Electrochemical Science Advances, Vol 3, Iss 6, Pp n/a-n/a (2023)

Abstract The hydrogen evolution reaction (HER), the key reaction for electrocatalytic production of hydrogen, is of fundamental importance due to its simplicity yet is very important for renewable energy. Notwithstanding, Pt is still the main catalys

Emergence of local scaling relations in adsorption energies on high-entropy alloys

Autor: Wissam A. Saidi

Publikováno v: npj Computational Materials, Vol 8, Iss 1, Pp 1-7 (2022)

Abstract Alloying has been proposed to circumvent scaling relations between the adsorption energies thus allowing for the complete optimization of multistep reactions. Herein the fidelity of scaling rules on high-entropy alloy (HEA) surfaces is asses

Unusual layer-by-layer growth of epitaxial oxide islands during Cu oxidation

Autor: Meng Li, Matthew T. Curnan, Michael A. Gresh-Sill, Stephen D. House, Wissam A. Saidi, Judith C. Yang

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)

Understanding metal oxide growth mechanisms is essential for the precise design and fabrication of nanostructured oxides. Here, the authors use correlated in situ ETEM, data analysis, and DFT to show an unusual layer-by-layer adatom growth mechanism

Stability and electronic properties of two-dimensional metal–organic perovskites in Janus phase

Autor: Guangren Na, Yawen Li, Bangyu Xing, Yilin Zhang, Xin He, Wissam A. Saidi, Lijun Zhang

Publikováno v: APL Materials, Vol 9, Iss 11, Pp 111105-111105-7 (2021)

Two-dimensional (2D) hybrid metal–organic perovskites have been widely studied due to their good stability and unique optoelectronic properties. By incorporating different ligands on opposite sides of the inorganic octahedron plane, we construct a
