Highly efficient photocatalysts constructed by rational assembly of dual-cocatalysts separately on different facets of BiVO₄

Abstract

Rational construction of dual cocatalysts corresponding to different facets with photogenerated charge separation.

The new breed of cutting-edge catalysts

“…At the Chinese Academy of Sciences' State Key Laboratory of Catalysis in Dalian, director Can Li has used platinum and cobalt oxide nanoparticles to create a catalyst for splitting water with sunlight 10 (see 'Light splitter'). He starts by sticking the nano particles to crystals of a semiconductor called bismuth vanadium oxide, with each type of particle carefully isolated on a specific face of each crystal.…”

Nanoscale Effects in Water Splitting Photocatalysis

“…This is shown for BiVO 4 microcrystals in Fig. 16e, f. The selective deposition of Pt and MnOx suggests that charge carriers accumulate at (010) and (111) facets of the crystal [166].…”

“…Many transparent n-or p-type metal oxides are known to accept electrons or holes [165]. (e) BiVO 4 microcrystals after labeling with Pt and MnOx (f) [166]. Reproduced from [166] with permission from The Royal Society of Chemistry F.E.…”

TiO2 porous ceramic/Ag–AgCl composite for enhanced photocatalytic degradation of dyes under visible light irradiation

“…The photocatalytic degradation process of MO and RhB is described by first-order kinetics [33,34] as expressed by: ln(C/C 0 ) = k app t, where k app is the apparent rate constant, C 0 and C are the concentrations of MO or RhB solutions at time of 0 and t, respectively. The pseudo-first-rate kinetic rate constant can be deduced from the linear fitting of ln (C 0 /C) versus irradiation time.…”
