Efficient fabrication of ZrO2-doped TiO2 hollow nanospheres with enhanced photocatalytic activity of rhodamine B degradation

Cu2O/TiO2 heterostructured hollow sphere with enhanced visible light photocatalytic activity

“…Nonmetallic elements, such as N [13] and F [4] were also applied to enhance the visible light photocatalytic activities of TiO 2 hollow microspheres. Moreover, coupling TiO 2 HS with materials sensitive to visible light, such as WO 3 [14], ZrO [15] or CdS quantum dot [16], has been proved a promising method to obtain visible light absorption for TiO 2 HS. However, metallic and non-metallic elements doping always leads to unstable materials which undergoes corrosion and the degree of doping is difficult to control.…”

Engineering the Cu2O–reduced graphene oxide interface to enhance photocatalytic degradation of organic pollutants under visible light

“…S3. All the composites had isotherms of type IV from the Brunauer-Deming-Deming-Teller (BDDT) classification[28], and the pore size distributions of Cu 2 O-rGO were similar. From Table.…”

Synthesis of sandwich-like TiO2@C composite hollow spheres with high rate capability and stability for lithium-ion batteries

“…Both the isotherms corresponding to TiO 2 -HS and TiO 2 -HS@C are type IV (BDDT classification) with hysteresis loops at high relative pressure, suggesting the presence of mesopores (2e50 nm) and macropores (>50 nm). The shape of the hysteresis loop is type H3, suggesting narrow slitshaped pores that are probably generated by the porous shells in TiO 2 -HS [33]. During the carbon-coating process, carbon will fill the pores in TiO 2 -HS, which can be confirmed by the decrease of pore volume in TiO 2 -HS@C. Moreover, the corresponding pore size distribution results (Fig.…”
