Anatase TiO2 single crystals with exposed {001} and {110} facets have been successfully synthesized using a modified hydrothermal technique in the presence of hydrogen peroxide hydrofluoric acid solution; these exhibited enhanced photocatalytic activities for degradation Methylene Blue dye under ultraviolet light irradiation.
Abstract Over the past decades, various photocatalysts have been developed and great progress has achieved in field of solar‐driven photocatalytic water splitting. However, lack an accurate comprehensive evaluation method greatly hinders meaningful comparison between different systems becomes a serious impediment for development photocatalysts. Although many researchers are aware this, there little work this area. In Viewpoint, we first analyze insufficiencies existing methods then make...
Flower-like TiO2 nanostructures with exposed {001} facets were synthesized by a low-temperature hydrothermal process from Ti powders for the first time, and they exhibited enhanced photocatalytic degradation of methylene blue dye under ultraviolet light irradiation.
The effect of particle size and active surfaces on photoreactivity TiO2 crystals is investigated in this report. clarification highly the key to understanding anatase crystal also morphological control photocatalysts with well-defined facets. single different percentage {001} facets uniform size, as well particles same facets, are synthesized by carefully controlling synthesis parameters. Their photooxiation reactivity results indicate that underlying dominant factor for photooxidation...
This review presents the recent progress of photocatalytic conversion CH<sub>4</sub> to CH<sub>3</sub>OH from four aspects: photocatalysts, oxidants, sacrificial reagents, and activation mechanisms, along with its current status existing challenges.
The Pt/b-TiO 2 NF photocatalyst is deactivated due to the accumulation of product H inhibits forward reaction and gradual substitution O for in absorption site on surface, its stability can be improved a simple way.
Abstract Hierarchical TiO 2 nanospheres with controlled surface morphologies and dominant {001} facets were directly synthesized from Ti powder by a facile, one‐pot, hydrothermal method. The obtained hierarchical have uniform size of 400–500 nm remarkable 78 % fraction facets. influence the reaction temperature, amount HF, time on morphology exposed was systematically studied. A possible growth mechanism speculates that first dissolves in HF solution, then flowerlike nanostructures are...
The spatial separation of reduction and oxidation reaction sites on the different facets a semiconductor is an ideal promising route for overall photocatalytic water splitting due to efficient charge carrier separation. Rutile TiO2 has separate crystal can be used achieve direct pure under ultraviolet (UV) light irradiation. In order improve rate reaction, ratio rutile should regulated controllably. However, preparation architecture been limited by availability synthetic techniques. this...
The efficient conversion of methane (CH4) to high-value-added chemicals using a photocatalyst at room temperature and pressure faces great challenges compared harsh reaction conditions. However, achieving this would yield substantial cost advantages hold immense potential for development. Here, we demonstrate the enhanced photocatalytic efficiency CH4 conditions without requiring any oxidant through construction bimetal Ag–Cu-loaded brookite TiO2 photocatalyst. C1 products were ultimately...
Single-walled carbon nanotubes (SWNTs) became soluble in water and formed a stable solution when l-phenylalanine (Phe) was adsorbed. The adsorption selectivity of Phe zwitterions for larger diameter SWNTs confirmed by analysis Fourier transform infrared spectra differential thermogravimetric analysis. Enhanced on the oxidized single-walled (OSWNT) observed comparison with that purified (PSWNT). are thought to adsorb surface OSWNT joint interaction π−π stacking, hydrogen bond, part covalent...
In this article, we investigated the interactions between oxidized single-wall carbon nanotubes and three amino acids. A simple environmental benign method to realize solubility of (OSWNT) in water was described. The acids used study include l-glycine (Gly), l-lysine (Lys), l-phenylalanine (Phe). OSWNT became soluble under ambient conditions formed a stable suspension when (AA) were adsorbed on it. AA characterized by transmission electron microscopy (TEM), scanning (SEM), Raman...
