In situ construction of a C3N5 nanosheet/Bi2WO6 nanodot S-scheme heterojunction with enhanced structural defects for the efficient photocatalytic removal of tetracycline and Cr(vi)

“…Generally, textural characteristics play a crucial role in the photocatalytic performance of a catalyst. [67][68][69] Thus, the BET surface areas of the samples were determined by their N 2 adsorption-desorption isotherms. 70 As presented in Fig.…”

One-Step Hydrothermal Synthesis of Anatase TiO2 Nanotubes for Efficient Photocatalytic CO2 Reduction

“…Such a technique could minimize CO 2 emissions and be used in the chemical process industries and fuels. Photocatalytic CO 2 reduction is an excellent green chemistry technology for directly converting CO 2 by natural sunlight into fuels such as CO, CH 4 , CH 3 OH, etc. , It is known that the CO 2 photocatalysis efficiency of photocatalyst depends on its physicochemical properties, the position of the conduction band (CB), the ability for light absorption, photon energy, light intensity, surface catalytic active sites, e – /h + separation, and adsorption and desorption of reactants and intermediates. − However, semiconductors are promising photocatalysts, − in specific TiO 2 nanoparticles, due to their stability, abundance, cost-effectiveness, and corrosion resistance. The only barrier for TiO 2 is its wide bandgap which can be enhanced by doping with other nonmetals, metals, or their oxides. − …”

Facile Preparation of Highly Active CO2 Reduction (001)TiO2/Ti3C2Tx Photocatalyst from Ti3AlC2 with Less Fluorine

“…TiO 2 is an extremely attractive candidate for photocatalysis, given the multiple advantages of low price, chemical durability, and ecological friendliness [1,2]. However, realistic applications of TiO 2 are restricted due to the rapid recombination of photogenerated electron-hole pairs.…”
