A novel preparation of three-dimensionally ordered macroporous M/Ti (M=Zr or Ta) mixed oxide nanoparticles with enhanced photocatalytic activity

Electrospinning preparation, characterization and photocatalytic properties of Bi2O3 nanofibers

“…Upon excitation, the separated electrons and holes can follow surface of solid. Therefore, the narrower band gap, the easier it is to excite electrons from the valence band to the conduction band [34]. The difference in the band gap thus leads to different photocatalytic behavior.…”

One-step sol–gel preparation and enhanced photocatalytic activity of porous polyoxometalate–tantalum pentoxide nanocomposites

“…This is due to a decrease of the CB levels via mixing of W5d and Ta5d orbitals. The lower band gap energy is benefited to improve the photocatalytic activity of the composites, since the electron transitions from the VB level to CB level become easier; therefore, more photogenerated electrons and holes could participate in the photocatalytic reactions [28].…”

Ag Nanoparticles‐Enhanced Photoluminescence in LaPO4: Eu Three‐Dimensional Ordered Macroporous Films

“…Three‐dimensionally ordered macroporous (3DOM) films consists of a nano‐sized skeleton surrounding uniform close‐packed macrospores interconnected through windows, which have aroused many researchers' attention in the fields of photonic crystal, electrode, separation, and catalyst support . Meanwhile, the 3DOM films with open pores offer many sites for the accommodation of functional bio‐molecules and drugs, which makes it very attractive in medical and biological fields.…”
