Designing a novel visible-light-driven heterostructure Ni–ZnO/S-g-C3N4 photocatalyst for coloured pollutant degradation

“…16,17 The researchers are engaged to solve these problems to make efficient photocatalysts and developed various types of photocatalysts. 18,19 Among these, the heterogeneous photocatalyst is a good choice due to its efficiency under visible light. [19][20][21] The efficiency of heterostructure photocatalysts depends upon bandgap position, bandgap energy, composition, morphology, surface area, and photostability.…”

Snowflake-like Cu2S Coated with NiAl-LDH Forms a p–n Heterojunction for Efficient Photocatalytic Hydrogen Evolution

“…Here, the light absorption performance of the photocatalyst is characterized by the UV–vis diffuse reflectance spectrum. First, it can be seen from Figure a,b that Cu 2 S exhibited the best light absorption ability, which is greatly related to its own structural characteristics; due to the many branches of the snowflake structure, visible light is fully utilized after several reflections. In addition, the single LDH-1 and LDH-2 showed three types of absorption bands between the wavelength regions of 250–800 nm; the absorption bands between 200 and 300 nm are caused by the ligand-to-metal charge transfer between oxygen 2p and Ni 2+ ion 3d orbitals, while the absorption bands between 300–500 and 500–800 nm are octahedral coordination features of the bivalent Ni 2+ . , Due to the d 8 octahedral field fusion of Ni 2+ ions, the absorption peaks at 741 and 380 nm correspond to the spin transition 3 A 2g (F) → 3 T 1g (F) and 3 A 2g (F) → 3 T 1g (P), respectively, while the absorption bands at 415 and 656 nm correspond to the spin-forbidden transition 3 A 2g (F) → 1 Eg­(D) and 3 A 2g (F) → 3 T 1g (D), respectively .…”

“…Cu 2 S is a p-type semiconductor with excellent photoelectric properties and has the advantages of low cost and good photocatalytic performance. These excellent properties are largely related to the size and structure of Cu 2 S itself . In recent years, many pioneers have studied various Cu 2 S catalysts with different morphologies such as nanoparticles, nanocrystals, and nanowires .…”

In recent years, many pioneers have studied various Cu 2 S catalysts with different morphologies such as nanoparticles, nanocrystals, and nanowires . In 2018, Zhang’s group reported the preparation of snowflake Cu 2 S, which not only has a high specific surface area but also has a strong ability to capture and scatter light, thus possessing a high photocatalytic activity .…”

Improving the Thermal Behavior and Flame-Retardant Properties of Poly(o-anisidine)/MMT Nanocomposites Incorporated with Poly(o-anisidine) and Clay Nanofiller

“…Nanotechnology effectively addresses products with at least one aspect in the nanometer spectrum [ 8 , 9 , 10 , 11 ]. Nanotechnology involves buildings and systems with fresh characteristics owing to the configuration of their atoms [ 12 , 13 , 14 ]. Nanocomposites are, in fact, mixtures in which one of the parts at the nanometer stage is available.…”
