“…Compared to the standard card (PDF#75-2481), the characteristic peaks of the prepared ellipsoidal BiVO 4 at 18.8°, 28.8° and 30.5° correspond to the (101), (112) and (004) crystal planes, respectively, and can be identified as monoclinic BiVO 4 . 25,26 The characteristic peaks of CdS QDs belong to the cubic crystal structure with poor crystallinity, consistent with the standard card (PDF#75-0581). The characteristic peaks of the composites with in situ grown CdS QDs show little change compared to those of pure BiVO 4 , possibly due to the lower loading of CdS QDs and their poor crystallinity.…”

“…The obtained BiVO4 films were annealed in the air for three hours at 773 К. 15,23 The structure of the films was investigated by X-ray phase analysis on a DRON-4 diffractometer. The film thickness was measured by scanning electron microscopy with elemental analysis of the film thickness by oxygen on an EVO 50 XVP microscope.…”

“…BiVO4 is a promising and easy-to-obtain materials for converting solar energy into electricity. [13][14][15] Unlike chalcogenides and some oxides, BiVO4 is a more advantageous material because these compounds contain cadmium and plumbum. In addition, there is an urgent need to increase the stability of semiconductor sensitizers based on widely used cadmium sulfide and selenide.…”

In order to find new functional materials and materials with improved performance for next-generation electrochemical devices, several new materials for various purposes have been synthesized. In particular, BiVO4 films were obtained by electrochemical synthesis using interferometric control of film thickness during their deposition. Previously, it was found that the use of thin BiVO4 films with a thickness of 150 to 400 nm is most effective, where was observed an increase in the quantum yield of photocurrent up to 0.25 at ? = 400 to 450 nm. LiFePO4 was synthesized in DES medium (low-temperature eutectic solvents): choline chloride-triethylene glycol (ChCl-TEG) and choline chlorideethylene glycol (ChCl-EG) using NH4FePO4 and CH3COOLi as precursors. It was found that the mode of synthesis of LiFePO4/C at 973 ? for 1 h does not lead to oxidation of LiFePO4, as evidenced by the values of the ratio Fe2+/Fe3+ for LiFePO4 and LiFePO4/C, which are 2.4 and 2.7, respectively. It was found that the substitution of part of lead cations (up to 20 mol.%) in the composition of the fluorideconducting phase Pb0.86Sn1.14F4 contributes to the increase of its conductivity in the whole temperature range, and to a greater extent, the higher the concentration of the substituent. Charge transfer is provided by highly mobile interstitial fluorine anions, the concentration of which increases with increasing temperature and substituent content.

“…2.4 eV) and energy-level alignment, high oxidation potential, and abundant source, and thus, has been widely applied in the PEC water oxidation reaction . However, BiVO 4 still inevitably suffers from fast charge recombination and sluggish water oxidation kinetics, greatly limiting its overall quantum efficiency. , Constructing heterostructure via applicable interface engineering provides a feasible strategy to surmount the generic bottlenecks of BiVO 4 and especially stimulate the charge-transfer impetus of BiVO 4 -based photoanodes. Thus far, design of BiVO 4 /metal NC hybrid photoelectrodes has not yet been reported due to the lack of suitable synthetic approach considering the temperature-dependent or light-induced instability of metal NCs and the deficiency of appropriate energy-level alignment between BiVO 4 and metal NCs.…”

Atomically precise metal nanoclusters (NCs) have been deemed as a new generation of metal nanomaterials because of their characteristic atomic stacking fashion, quantum confinement effect, and multitude of active sites. The discrete molecular-like energy band structure of metal NCs endows them with photosensitization capability for light harvesting and conversion. However, applications of metal NCs in photoelectrocatalysis are limited by the ultrafast charge recombination and unfavorable stability, impeding the construction of metal NC-based photosystems. In this work, we elaborately crafted multilayered metal oxide (MO)/(metal NCs/insulating polymer) n photoanodes by a facile layer-by-layer (LbL) assembly technique. In these welldefined heterostructured photoanodes, glutathione (GSH)-wrapped metal NCs (Ag x @GSH, Ag 9 @GSH 6 , Ag 16 @GSH 9 , and Ag 31 @GSH 19 ) and an insulating poly(allylamine hydrochloride) (PAH) layer are alternately deposited on the MO substrate in a highly ordered integration mode. We found that photoelectrons of metal NCs can be tunneled into the MO substrate via the intermediate ultrathin insulating polymer layer by stimulating the tandem charge transfer route, thus facilitating charge separation and boosting photoelectrochemical water oxidation performances. Our work would open a new frontier for judiciously regulating directional charge transport over atomically precise metal NCs for solar-to-hydrogen conversion.
