Article Synopsis
- EUK-134 effectively catalyzes the dismutation reaction of superoxide radicals, with a lower activation energy compared to non-catalytic reactions.
- For the non-catalytic dismutation of hydrogen peroxide, the most favorable reaction path is identified as MEP3, which has the lowest activation energy among three possibilities.
- In the two-step dismutation reaction of hydrogen peroxide catalyzed by EUK-134, the energy barrier is lower than non-catalytic reactions, with the Mn atom within EUK-134 acting as both an electron donor and acceptor.
Developing highly efficient photocatalysts for the hydrogen evolution reaction (HER) by solar-driven water splitting is a great challenge. Here, we study the atomistic origin of interface properties and the HER performance of all-inorganic iodide perovskite β-CsPbI/2H-MoS heterostructures with interfacial vacancy defects using first-principles calculations. Both CsI/MoS and PbI/MoS heterostructures have strong binding and dipole moment, which are enhanced by interfacial iodine vacancies ().
