Assembly of Ag3PO4 nanocrystals on graphene-based nanosheets with enhanced photocatalytic performance

Elaboration and characterization of nanoplate structured α-Fe2O3 films by Ag3PO4

“…367.8 and 374.0 eV respectively (Fig. S21), which are attributed to Ag(I) ions doped in hematite (Shen et al, 2014;Schon, 1973;Bai et al, 2013). Also, the high-resolution of P2p spectrum show that the P2p binding energy of 133.0 eV is consistent with the value for P in the PO 4 3+ (Castro et al, 2010;Moulder et al, 1992).…”

Synthesis and characterization of a quaternary nanocomposite based on TiO2/CdS/rGO/Pt and its application in the photoreduction of CO2 to methane under visible light

“…25,26 The process of electrons diffusing in the semiconductor is not efficient because of surface defects, which result in an increase in charge recombination processes (e À with h + ), thereby decreasing the photocatalytic efficiency. [29][30][31] This photocatalytic approach is more efficient than the use of small amounts of metal nanoparticles known as co-catalysts deposited onto the semiconductor surface or onto the surface of carbonaceous materials. Xia et al 27 reported that TiO 2 electrodes containing dispersed carbon nanotubes (MWCNTs) are more efficient in the photocatalytic reduction of CO 2 than analogous TiO 2 electrodes without the presence of the carbonaceous material.…”

Photocatalytic decolorization of methylene blue dye by Ag3PO4–AgX (X = Cl−, Br− and I−) under visible light

“…During the photocatalytic reaction, Ag 3 PO 4 is decomposed to Ag and PO 3À 4 that inhibits further photocatalytic activity [6]. Recently more attention has been paid to try to protect this reaction by the preparation of Ag 3 PO 4 composite photocatalysts for example, TiO 2 /Ag 3 PO 4 [7], Ag/Ag 3 PO 4 [8], Ag 3 PO 4 /graphene [9] etc. Silver halide (AgX) is one of the most useful materials that have received much attention to composite with Ag 3 PO 4 .…”
