Interface engineering of ZnO/In2O3 Z-scheme heterojunction with yolk-shell structure for efficient photocatalytic hydrogen evolution

Efficient degradation of VOCs using semi-coke activated carbon loaded ternary Z-scheme heterojunction photocatalyst BiVO4–BiPO4–g-C3N4 under visible light irradiation

“…( hν ) plot using the Kubelka–Munk function (where α is the absorption coefficient, ν is the frequency of light, and h is the Planck constant). 64 The bandgaps of pure BiPO 4 , pure BiVO 4 and pure g-C 3 N 4 are 3.21, 2.12 and 2.57 eV, respectively, and the bandgaps of BiPO 4 –BiVO 4 , PVCN, and PVCN/SAC are 2.21, 2.24 and 1.95 eV, respectively. The above results can be attributed to the formation of heterojunctions between the photocatalysts and the synergistic effect between the photocatalyst and SAC interfaces, which improves the separation and transfer of photogenerated carriers and leads to higher photocatalytic activity and absorption of visible light of these heterojunctions.…”

One‐Pot MOFs‐Encapsulation Derived In‐Doped ZnO@In2O3 Hybrid Photocatalyst for Enhanced Visible‐Light‐Driven Photocatalytic Hydrogen Evolution

“…In addition, the H 2 -evolution rate of present In-doped ZnO@In 2 O 3 photocatalyst is also superior to those of most visible-light-driven ZnO-based photocatalysts, even exceeds the full spectrum rates of plentiful ZnO-based catalysts as shown in Figure 6e and Table S1, Supporting Information. [22,[38][39][40][41][42][43][44][45][46][47][48][49][50][51]…”

“…[21] Moreover, Duan et al prepared ZnO/In 2 O 3 hollow spheres for H 2 production and obtained a yield of up to 240.41 µmol•g −1 •h −1 . [22] Though a few studies on ZnO-In 2 O 3 composites for photocatalysis have been reported, to the best of our knowledge, no detailed study is available on the In-doped ZnO@In 2 O 3 composites for visible-light-driven photocatalytic activity.…”

Carbon-Dots-Modified Hierarchical ZnIn2S4/Ni–Al LDH Heterojunction with Boosted Charge Transfer for Visible-Light-Driven Photocatalytic H2 Evolution

“…The overuse of fossil fuels can cause the current energy shortage and irreversible environmental damage. In order to reduce the unrestrained consumption of nonrenewable resources, the clean energy (e.g., H 2 ) production by photocatalytic water splitting can be considered a promising way to solve the above issues. − At present, many types of photocatalysts have been found, such as metal oxides (TiO 2 , ln 2 O 3 , Fe 2 O 3 , etc), metal sulfides (CdS, CdZnS, ZnIn 2 S 4 , etc), and carbon materials (carbon dots, carbon nitride, carbon nanotube, etc). Among these photocatalysts, the hexagonal ZnIn 2 S 4 , as a ternary chalcogenide with unique 2D layered structure, appropriate band gap, and robust resistance to photocorrosion, is one of the most favorable catalyst for photocatalytic H 2 generation under visible-light illumination .…”
