Construction of CdS/CoOx core-shell nanorods for efficient photocatalytic H2 evolution

Nanoscale Assembly of BiVO4/CdS/CoOx Core–Shell Heterojunction for Enhanced Photoelectrochemical Water Splitting

“…To characterize the structure and the crystalline quality of such composite, HR-TEM and energy-dispersive X-ray spectroscopy (EDS) analyses were conducted. The EDS elemental mapping confirmed that CdS was homogeneously deposited on the surface of BiVO 4 ((Figure 3e-h), while CoO x formed a homogeneous shell on the top CdS layer (Figure 3i-k), a desired characteristic for metal oxides serving as co-catalysts [46,47]. The inter-planar spacing of~0.298 nm (102), 0.309 nm (101), 0.314 nm (101), 0.349 nm (100), and 0.353 (100) with corresponding CdS planes in brackets is clearly observed in Figure 3m,n [44].…”

Novel prism shaped C3N4-doped Fe@Co3O4 nanocomposites and their dye degradation and bactericidal potential with molecular docking study

“…37 Vivid optical response under visible light and good charge transfer efficiency of Co 3 O (B g ¼ 2.6 eV) makes it highly valuable. 28,38 One difficulty, however, is the severe aggregation of Co 3 O 4 nanoparticles, which causes massive reduction in photocatalytic activity. 39 To overcome this, suitable semiconductors can be doped in Co 3 O 4 or highly rened synthesis techniques could be adopted to fabricate dispersed Co 3 O 4 nanoparticles.…”

Cuboidal Cu 2 O nanoparticles dispersed granular Mn 0. 05 Cd 0 . 95 S form a p‐n heterojunction for efficient photocatalytic hydrogen evolution

“…The semiconductor photocatalytic hydrogen evolution technology with broad development potential has been continuously studied in depth. 4 There are many photocatalytic materials such as TiO 2 , [5][6][7][8] non-metallic semiconductor g-C 3 N 4 , [9][10][11] and CdS [12][13][14][15][16] with the advantages of pollution-free, cheap, and high chemical stability, respectively, which are essential to organic degradation and photocatalytic hydrogen production. However, these traditional photocatalytic materials usually have many shortcomings, such as narrow light absorption range and electrons combine with holes easily.…”
