Key Factors

Bamboo charcoal (BC) as an environmentally friendly and low-cost material receives widespread attention. Recently, much attention has been focused on the use of BC as adsorbent to treat wastewater. This paper provides an overview of the adsorption of organic contaminants in solution by using BC. The sorption behaviors of BC with various organic pollutants, and the kinetic model adopted to explain the adsorption rate of organic pollutants from aqueous solution were also reviewed. The adsorption capacity, the isotherm model, and several key factors such as modification, surface area, are discussed in this paper. Possible improvement of BC to treat organic contaminants in aqueous solution is also proposed.

BiOCl/SnS2 core-shell heterojunction is prepared by a facile and economic hydrothermal method. The obtained BiOCl/SnS2 heterojunction displays high photocatalytic activity in the degradation of Rhodamine B (RhB). The high performance is explained by the fast separation of the photoinduced electron–hole pairs promoted by the heterojunction. The cycle life of the heterojunction is also improved compared with individual BiOCl or SnS2.

In this study titanium dioxide nanotube (TNT) were prepared by anodization method. The effects of the temperature, time and voltage on the anodization process were investigated in detail. Photocatalytic activity of the TNT films was evaluated in terms of the degradation of methylene blue in aqueous solution under UV light irradiation. The results showed that the optimization of temperature, voltage and time on anodization process were 45oC, 20 V and 1 day, respectively. Consequently, these results indicate that the optimization of anodization process is critical to achieve the high performance of photocatalytic reaction.

Zno Nanocrystals

Here, we demonstrate for the first time a strategy to self-assemble ZnO nanoparticles (NP) on a large area by a facile one-step process. First, rough and random ZnO nanocrystals (NC), were produced by free-stabilizing aqueous synthesis. Therefore, a post thermal treatment at various temperatures ranging from 80 to 800 °C was necessary to obtain size-tunable and photoluminescent crystalline NP. The fabricated NP had both efficient UV photoluminescence and photocatalytic activity by photo-degradation of Methylene Blue (MB) dye. The annealed NP showed an absorption blue shift in the UV region with decreasing size. This shift was attributed to high quantum confinement effect since ZnO NP diameter reached values lower than the Bohr radius of ZnO (~2.7 nm). The photocatalytic activity displayed dependency on the particle’s size, number, and crystallinity. Subsequently, the NP were self-assembled inside poly(methyl methacrylate) (PMMA) nanoholes. Subsequently, large area substrate of homogenous properties ZnO NP was obtained. Moreover, the synthesis facility, photoemission and photocatalytic properties of ZnO NP could be a new insight into the realization of high performance and low cost UV laser devices.
