Synthesis of C, Ag co-modified TiO2 photocatalyst and its application in waste water purification

Co-doped MoS2 NPs with matched energy band and low overpotential high efficiently convert CO2 to methanol

“…The different kinds of combination between sulphur and metal ions lead to different compact degree of the structure, which would directly affect the catalytic activity of transition metal sulfides [4,5]. For example, the structure of some transition metal sulfides is too compact to increase the surface area, leading to the decrease of the contact interface of reactants and the reduce of catalytic activity, such as NiS [6]; and the structure of some transition metal sulfides is too loose, which own more contact area with reactants, however, their stable structure is difficult to be broken, so the catalytic performance is low, just like MnS [7]. Whether the compact degree is high or low, it does harm to catalytic activity and MoS 2 is found to possess an appropriate compact degree [8].…”

Preparation and characterization of graphene oxide/Ag2CO3 photocatalyst and its visible light photocatalytic activity

“…Up to now, one of the most used photocatalysts is TiO 2 . TiO 2 photocatalyst has some advantages such as good stability, nontoxicity, high activity and low cost [8][9][10][11][12][13][14][15][16].…”

A review on plasmonic metal⿿TiO2 composite for generation, trapping, storing and dynamic vectorial transfer of photogenerated electrons across the Schottky junction in a photocatalytic system

“…Contrarily in another study the deposition of Ag on the surface of P25 containing both anatase and rutile phases had negligible effect on the degradation of aspartic acid, while reaction rate was quite high with either anatase or rutile individually [128]. C/Ag/TiO 2 microspheres synthesized via controlled hydrolysis of tetrabutyl titanate in ethanol medium and followed by calcination process using AgNO 3 as Ag source and citric acid as carbon source showed an enhanced the photocatalytic activity for RhB degradation under UV as well as visible light region compared to pristine TiO 2 and Ag/TiO 2 [129]. The addition of citric acid to the system largely increased the Ag density due to its reductive property and it can also induce the disorderness of sp 2 orbitals of carbon during the heat treatment (500 • C for 2 h) which gets coated on TiO 2 surface.…”
