Accelerating water oxidation on BiVO₄ photoanodes via surface modification with Co dopants

Abstract

Despite the vast investigations on improving the photoelectrochemical performance of BiVO4 for water splitting, charge recombination in the near-surface region remains a challenge. In this study, we showed that the...

Advanced electron paramagnetic resonance in chemical energy conversion: current status and future potential

“…99 EPR can detect OVs, both at the surface and in the bulk medium in a wide range of substrates, e.g. titanium-based catalysts (TiO 2 , SrTiO 3 ), 12,68,75,83,100,101 bismuth-based catalysts (Bi 24 O 31 Br 10 , BiOCl, Bi 2 O 3 , BiVO 4 , BiO x , Bi 5 O 7 Br), 102–105 tungsten-based catalysts (WO 3 , W 18 O 49 ), 106 SnO 2 , 107,108 CuCr-LDH, 109 CuO, 110 Fe 2 O 3 , 111 Cu 2 O@CuNiMo 112 and CuZnAl-LDH. 79 OVs usually give rise to an isotropic, single-line EPR signal centered at around g ≈ 2.0.…”

Profound influence of surface trap states on the utilization of charge carriers in CdS photoanodes

“…In addition to these possible solutions, it has been reported that the controlled growth of semiconductors with the help of surface-active reagents can also have an impact on their photocatalytic and PEC activities. 14,15 Surfactants such as polyethylene glycol (PEG), sodium dodecyl sulfide (SDS), thioglycerol (TG), and hexadecyltrimethylammonium bromide (CTAB) are used as stabilizing reagents in order to control the direction and the extent of the particle growth and to manipulate the optical and structural characteristics of the nanomaterials. [16][17][18] In comparison to other surfactants, CTAB is less toxic and cheaper as a capping agent alternative which is significantly utilized for the synthesis of CdS colloidal particles.…”

Boosting the Capacitor Performance of the Metal Organic Frameworks Derived V2O5 Nanoflower by Cu Doping
