Application of CuS–ZnS PN junction for photoelectrochemical water splitting

Amino-functionalized MIL-101(Cr) photodegradation enhancement by sulfur-enriched copper sulfide nanoparticles: An experimental and DFT study

“…There are several traditional techniques for the remediation of dye molecules in wastewater, including physical and biological technologies that are, however, incapable of achieving efficient degradation of the dye molecules [3][4][5][6][7][8]. In recent years, interest has grown into the use of solar energy and semiconductor photocatalysis in water purification, properties [24][25][26][27][28][29][30][31]. It is a p-type semiconductor with a broad reported range for its bandgap (1.63-2.56 eV) [32,33].…”

3D-printed Cu2O photoelectrodes for photoelectrochemical water splitting

“…41 under dark conditions is slightly larger than that of the ptype Cu 2 O due to enhanced generation of minority carriers in the depletion region of the p-n junction. 40,48 We also studied the variations in PEC performance of the pn homojunction Cu 2 O photoelectrode due to different shapes, i.e., planar or 3D pyramid, with respect to the total light absorption area (A a ) of the electrode. The 3D photoelectrode consisted of 400 pyramids, each with a xed L b of 490 mm, which were printed in close contact without gaps (Fig.…”

Graphitic carbon nitride (g‐C3N4)‐based nanosized heteroarrays: Promising materials for photoelectrochemical water splitting

“…On the other hand, the photoelectrodes also provide catalytically active sites to decompose water molecules into hydrogen and oxygen molecules. So far, many kinds of materials have been developed as photoelectrode materials to achieve an efficient PEC water splitting, including metal oxides (eg, TiO 2 , ZnO, WO 3 , α-Fe 2 O 3 , Cu 2 O, NiO, and Co 3 O 4 ), [31][32][33][34][35][36][37] metal chalcogenides (eg, CdS, CdSe, ZnS, CuS, PbS, and MoS 2 ), [38][39][40][41][42][43] and metal (oxy)nitrides (eg, Ta 3 N 5 , GaN, InN, TaON, LaTiO 2 N, and CaNbO 2 N), [44][45][46][47][48][49] etc.…”
