One‐Step Solvothermal Synthesis of a Carbon@TiO₂ Dyade Structure Effectively Promoting Visible‐Light Photocatalysis

Abstract

A C@TiO2 visible‐light “dyade”‐like structure, catalytically active over the whole visible‐light spectrum, has been produced in a one‐step low‐temperature solvothermal process.

Carbon coated Au/TiO2 mesoporous microspheres: a novel selective photocatalyst

“…Integrating photo-inactive carbon as a co-adsorbent was also reported to increase the photocatalytic activities of TiO2 due to the synergistic effect of the high adsorption capacity of carbon and the photocatalytic activity of TiO2 [26,27]. Therefore, photocatalytic selectivity can be achieved when carbon materials with selective adsorptive properties are introduced into TiO2/carbon composites.…”

Photocatalytic Degradation of Rhodamine B over Sulfated SiO2-TiO2 Composite by Sulphuric Acid Impregnation Method

“…Titania is the most investigated semiconductor photocatalyst in solar energy conversion and environmental applications because of its low toxicity, low cost, abundance, high photostability, chemical resistance and high efficiency (2)(3)(4). V. Murugesan et al (5,6) has confirmed that titania can efficiently degrade the different dyes not only under UV irradiation but also under solar light irradiation.…”

“…This causes the SiO 2 -TiO 2 composite to adsorb more hydroxyl groups on the particle surface, which is beneficial for photocatalytic reaction (13). Regarding to the surface properties, modification of the titania with different anions such as SO 4 2-, PO 4 3-, and WO 4 2-has been found to enhance the acidity and certain other physicochemical properties of the catalyst (14)(15)(16). In particular, sulfation of semiconductor photocatalysts is of great interest for scientists because it has an enormous potential for environmental pollutant remediation (17,18).…”

Hybrid metal oxide@biopolymer materials precursors of metal oxides and metal oxide-carbon composites

“…165) Pyrolysis leading to MO@C is increasingly studied due to the complementarity of the two components, MO and C, for some applications like catalysts and electrodes. This is generally done in nitrogen, vacuum or argon leading for examples to LiFePO 4 / C, 74) or TiO 2 @C. 66),134),229), 230) Although not yet well investigated, the formation of these composites by a solvothermal/ dehydration process was recently reported, 111) this approach is linked to the developments of the cellulose-to-carbon process 33),231)236) and to the one of the production of biofuel and biochemical from biopolymers. Both processes can be highly modified by the presence of acid and inorganic compounds to base metal.…”
