Active high-entropy photocatalyst designed by incorporating alkali metals to achieve d0+d10+s0 cationic configurations and wide electronegativity mismatch
Jacqueline Hidalgo-Jimenez, Taner Akbay, Tatsumi Ishihara +1
Photocatalytic hydrogen (H2) production and carbon dioxide (CO2) conversion to methane (CH4) are considered promising solutions for reducing CO2 emissions. However, the development…
Understanding high photocatalytic activity of the TiO2 high-pressure columbite phase by experiments and first-principles calculations
Jacqueline Hidalgo-Jimenez, Taner Akbay, Tatsumi Ishihara +1
The clean production of hydrogen as a zero-emission fuel can be done using photocatalysis, with TiO2 being one of the most promising photocatalysts. However, the activity of TiO2 a…
Photocatalytic Carbon Dioxide Methanation by High-Entropy Oxides: Significance of Work Function
Jacqueline Hidalgo-Jiménez, Taner Akbay, Xavier Sauvage +2
Methane (CH4) formation from photocatalytic carbon dioxide (CO2) conversion in water is currently of interest because methane is a fuel, and it can also be transformed into other u…
Mixed atomic-scale electronic configuration as a strategy to avoid cocatalyst utilization in photocatalysis by high-entropy oxides
Jacqueline Hidalgo-Jiménez, Taner Akbay, Xavier Sauvage +2
To enhance the activity of photocatalysts for hydrogen production and CO2 conversion, noble metal cocatalysts as electron traps and/or acceptors such as platinum or gold are usuall…
Photoreforming of plastic waste into valuable products and hydrogen using a high-entropy oxynitride with distorted atomic-scale structure
Ho Truong Nam Hai, Thanh Tam Nguyen, Maiko Nishibori +2
The persistent existence of plastic waste causes serious problems for the environment, directly and indirectly affecting the health of organisms and humans. Photoreforming is a nat…
Mechanism of anatase-to-columbite TiO2 phase transformation via sheared phases: first-principles calculations and high-pressure torsion experiments
Jacqueline Hidalgo-Jimenez, Taner Akbay, Yuji Ikeda +2
High-pressure torsion (HPT) can facilitate phase transformations in titanium dioxide (TiO2) and stabilize its high-pressure columbite phase, as an active photocatalyst, by shear st…
