TL;DR: In this paper, the role of the two different catalytic sites of pure cobalt and coexisting domains of cobalt metal and cobalt oxide has been evaluated, showing that surface cobalt atoms of the atomically thin layers have higher intrinsic activity and selectivity towards formate production, at lower overpotentials.

TL;DR: The role of defects in affecting electron-hole separation at atomic level is uncovers, opening new opportunities for achieving highly efficient solar CO2 reduction performances.

TL;DR: In this paper, single-unit-cell o-BiVO4 layers with rich vanadium vacancies were successfully synthesized for the first time, and the defect level and hole concentration near Fermi level were revealed.

TL;DR: surface photovoltage spectra and time-resolved fluorescence emission decay spectra indicate that the introduced oxygen vacancies promote the separation of carriers, and theoretical calculations reveal the creation of new defect levels resulting from the oxygen vacancies, which extends the photoresponse into the visible-light region.

TL;DR: Atomic layers for transition-metal oxides are proposed to address problems of conventional electrocatalysts through offering an ultralarge fraction of active sites, high electronic conductivity, and superior structural stability.
