Coupled Vacancy Pairs in Ni‐Doped CoSe for Improved Electrocatalytic Hydrogen Production Through Topochemical Deintercalation

Angewandte Chemie International Edition, Год журнала: 2020, Номер 59(50), С. 22743 - 22748

Vacancy engineering plays vital role in the design of high-performance electrocatalysts. Here, we introduced coupled cation-vacancy pairs Ni-doped CoSe to achieve boosted hydrogen evolution reaction (HER) activity through a facile topochemical intercalation approach. Adjacent Co vacancy and heteroatom Ni doping contribute together for upshift Se 4pz orbital, which induces larger overlap between 4p H 1s orbitals. As result, free energy adsorption can be lowered significantly. With an advanced HER 185.7 mV at 10 mA cm-2 , this work provides new direction guidance novel

Emerging Surface, Bulk, and Interface Engineering Strategies on BiVO₄ for Photoelectrochemical Water Splitting

Small, Год журнала: 2021, Номер 18(10)

Опубликована: Дек. 22, 2021

The photoelectrochemical (PEC) cell that collects and stores abundant sunlight to hydrogen fuel promises a clean renewable pathway for future energy needs challenges. Monoclinic bismuth vanadate (BiVO4 ), having an earth-abundancy, nontoxicity, suitable optical absorption, ideal n-type band position, has been in the limelight decades. BiVO4 is potential photoanode candidate due its favorable outstanding features like moderate bandgap, visible light activity, better chemical stability, cost-effective synthesis methods. However, suffers from rapid recombination of photogenerated charge carriers have impeded further improvements PEC performances stability. This review presents close look at emerging surface, bulk, interface engineering strategies on photoanode. First, effective approach surface functionalization via different cocatalysts improve kinetics discussed. Second, state-of-the-art methodologies such as nanostructuring, defect engineering, doping enhance absorption transport bulk are reviewed. Third, heterostructuring separation introduced. Lastly, perspectives foremost challenges some motivating outlooks encourage research progress this frontier offered.
