“…The XRD patterns of Ag 2 S&CdS-TNAs and CdS&Ag 2 S-TNAs are shown in Fig. 3a [33][34][35]. The weak diffraction peaks of Ag 2 S and CdS phases manifest that these particles render small sizes, in accordance with the a-few-nm range determined with TEM.…”

“…These results reveal that PEC performance of BiVO 4 can be well artificially regulated through p‐n hetero‐configuration. Silver sulfide (Ag 2 S), as a typical p‐type semiconductor, takes a narrow band gap (1.0 eV), which also greatly facilitates its solar harvesting ability ,. To integrate Ag 2 S with other semiconductors has realize efficient photodegradation of dyes and photocatalytic hydrogen production.…”

The unsatisfactory of solar absorption and charge separation is the main loss limiting the conversion efficiency in photoelectrochemical water splitting system. Here, Ag 2 S/BiVO 4 heterostructure have been fabricated for the first time to PEC splitting water, achieving efficient solar-to-chemical energy conversion. The Ag 2 S nanoparticles evenly distributing on the surface of BiVO 4 not only promotes the charge separation, but also greatly facilitates the surface hole injection. The results show that the optimal Ag 2 S/BiVO 4 heterostructure reach a remarkable photocurrent density of 1.91 mA/cm 2 at 1.23 V (vs RHE) under 100 mW/cm 2 irradiation, which is approximately 3.2-fold higher than that of bare BiVO 4 . The incident photon-to-current efficiency (IPCE) of Ag 2 S/BiVO 4 heterostructure have been enhanced up to 23 % in visible region (V bias = 1.23 V, 460 nm). In addition, Ag 2 S/BiVO 4 shows the attracting stability during photoelectrochemical process, since its photocurrent density can keep for 92 % after 2 h. The charges transfer mechanism for Ag 2 S/BiVO 4 heterostructure were also proposed. This work provides a new insight for constructing efficient and stable photoanodes based on BiVO 4 .

The article considers kinetic aspects study of hydrochemical deposition of solid phase Ag2S from solutions containing silver nitrate, ammonium hydroxide and sodium citrate at temperatures 303-343 K in the conditions of the spontaneous formation of solid phase.The authors conclude that: 1. Particular kinetic orders are defined on all components of reaction mixture and activation energy of this process is 37 kJ/mole.2. In the certain concentration limits formal kinetic equation was derived for the rate of conversion of silver salt into silver sulfide that allows to provide the regulation of the rate of silver sulfide phase formation in the investigated reaction mixture purposefully.
