Photogenerated electron-hole recombination has been a bottleneck problem for photocatalytic reactions for a long time. Herein, we propose an efficient solution strategy through capturing electrons and holes with
3(a)), suggesting that the recombination of electron-hole pairs was suppressed comparing with pristine ZIS. Moreover, electrochemical impedance spectroscopy (EIS) was conducted to investigate the transfer resistance of photo-generated electrons and holes [19], [22], [24]. The Nyquist plots can ...
During photocatalysis, the separation of electron-hole pairs within the semiconductor catalysts, combined with the following energy transfer processes, can readily generate a large amount of highly active species (such as radicals and singlet oxygen1,2,3,4. Notably, these active species could, under...
aAs we know, the substitution of O2 ions by F ions could influence the energy band structure of BiVO4 and act as electrons and holes traps by altering the photogenerated electron–hole pairs recombination rate. In detail, the photogenerated holes were trapped by surface lattice oxygen atoms, res...
aWhen the NaF concentration increased to 1:1.2, the PL intensity of the sample S4 instead increased, inferring that the excess F ions in BiVO4 crystal lattice could act as the recombination centers of photogenerated electron–hole pairs. 当NaF集中增加到1:1.2, S4的改为增加的PL强度样品,推断...
Electron and holeμin each layer can vary independently to account for additional recombination processes expected under illumination. Under illumination, radiative42,43,44, Auger9,45,46, and Shockley-Read-Hall47recombination take place along with photogeneration of carriers. Photogenerated hole or elect...
Photogenerated electron-hole recombination has been a bottleneck problem for photocatalytic reactions for a long time. Herein, we propose an efficient solution strategy through capturing electrons and holes with environmental factors. In this study, nanoscale iron molybdate (Fe-2(MoO4)(3)) was ...
This improved photocatalysis was attributed to the synergistic actions of CuO and ZnO consisting of their formed p–n hetero-interface for the extension of solar absorption and the anti-recombination of photogenerated electron–hole pairs, demonstrating the potential for p–n heterostructures to be ...
of two-dimensional semiconductor nanobubbles present remarkable potential for application in flexible optoelectronic devices, and the piezoelectric field has emerged as an efficacious pathway for both the separation and migration of photogenerated electron–hole pairs, along with inhibition of recombination. Ho...
Photocatalysis has turned out to be a promising solution with the environmental and economic benefits beheld, but the rapid recombination of photogenerated electron and hole inhibited the application in practice. This study proposed a rotating triboelectric nanogenerator (R-TENG) as a self-powered bias...
