One-Step Calcination to Gain Exfoliated g-C3N4/MoO2 Composites for High-Performance Photocatalytic Hydrogen Evolution

“…It can be seen from this figure that all the samples contain the two characteristic peaks of g-C 3 N 4 . The peak around 13.2° is indexed to the (100) crystal plane of g-C 3 N 4 (0.671 nm), which represents the tri-s-triazine repeating unit in the g-C 3 N 4 plane, while the peak around 27.6° is attributed to the (002) crystal plane of g-C 3 N 4 (0.323 nm), signifying the interlayer stacking conjugated aromatic system of g-C 3 N 4 in the vertical direction [ 13 , 16 ]. Remarkably, compared with those of bulk g-C 3 N 4 , the strengths of these two peaks of the other samples are relatively low.…”

“…As is well known, the rapid recombination of photogenerated carriers is another critical factor that seriously affects the photocatalytic efficiency of g-C 3 N 4 . To solve this problem, excepting the deposition of materials with high electrical conductivity onto the surface of g-C 3 N 4 , loading semiconductor materials onto the surface of g-C 3 N 4 nanosheets to form heterojunctions is a classical program, because it is also conducive to optoelectronic transmission on the two-dimensional layer-like structured g-C 3 N 4 [ 15 , 16 , 17 ].…”

A highly efficient visible-light-driven photocatalytic fuel cell with ZnIn2S4/PANI/TiO2/Ti photoanode for simultaneous degradation of rhodamine B and electricity generation

“…In order to elucidate the enhanced photocatalytic mechanism, empirical eqn (3) and (4) were usually employed to calculate the valence band (VB) and the conduction band (CB) potential of different components. 62 E VB = w À E e + 0.5E g (3)…”

A direct Z-scheme S-Co3O4/Bi2WO6 heterostructure for enhanced photoelectrocatalytic degradation of tetracycline under visible light

“…Therefore, it is practical to develop a novel semiconductor heterojunction photoanode material for the PEC of organic pollutant degradation. [26][27][28] In recent years, Bi 2 WO 6 , as a prominent semiconductor, has become popular for PEC research because of its proper E g (2.4-2.9 eV), 29 unique layered structure and optical properties, stable crystal structure, high charge transport efficiency, simple and low-cost preparation, non-toxicity and environmental friendliness. Unfortunately, pure Bi 2 WO 6 suffers from the disadvantages of low photoexcited e À /h + pair separation efficiency, limited specific surface area, and poor quantum utilization, which restrict its PEC performance.…”
