Black titania with increased defective sites for phenol photodegradation under visible light

Galvanic Deposition of Pt Nanoparticles on Black TiO2 Nanotubes for Hydrogen Evolving Cathodes

“…Its dark color assists the adsorption of sunlight [6] in a wide wavelength range, from ultraviolet up to the near‐infrared region,[ 7 , 8 ] due to the narrow bandgap and the mid‐gap electronic states. [9] This material has gained great attention in the field of photocatalysis for the production of H 2 gas during water splitting[ 3 , 4 , 10 , 11 , 12 , 13 ] and decomposition of organic pollutants such as phenol, [14] toluene, [15] ethyl acetate, [15] and methyl orange [16] in wastewater treatment. Except for its importance in the field of photocatalysis, its use expands to a wide range of applications in the field of electrochemistry, such as lithium‐ and sodium‐ion batteries,[ 3 , 4 , 17 , 18 ] supercapacitors, [19] and fuel cells.…”
