Cationic vacancy engineering of p-TiO2 for enhanced photocatalytic nitrogen fixation

“…p-TiO 2 (II) has a larger OCP value of 0.39 V compared to the 0.04 V open circuit voltage of n-TiO 2 . The increased energy band bending at the electrode/electrolyte interface represents an enhanced electron–hole separation, 54,55 which is consistent with the findings of the PL spectra.…”

Efficient Charge Separation and Transport in Fullerene-CuPcOC8 Donor–Acceptor Nanorod Enhancing Photocatalytic Hydrogen Generation

“…Copper phthalocyanine (CuPc) is an excellent organic pigment with high chemical stability to light and temperature [27]. CuPc is an effective donor material with remarkable tunability and high visible light absorption [28,29]. Due to these exceptional properties, a series of CuPc photocatalysts have been employed in the field of photocatalytic hydrogen generation [28,[30][31][32].…”

However, the current efficiency of most Pc-based photocatalysts for hydrogen generation is unsatisfactory.…”

Hollow Co3O4/CdS Nanoparticles for Photocatalytic Hydrogen Evolution and Photodegradation

“…45 Compared with nanowires, nanosheets, or nanotubes, the hollow core−shell nanospheres with more sufficient pn junction interfaces can promote carrier efficiency and increase solar efficiency via reflections of the inner cavity, 46 Yang et al used the CuPc/Zn 0.5 Cd 0.5 S core− shell hollow nanostructure to enhance the visible light hydrogen evolution activities via unique 3D microstructure. 47 For most reported core−shell nanostructures, the template method would be an easy and controllable method, 48,49 for instance SiO 2 or polystyrene microsphere template. Cheng et al fabricated the Fe 3 O 4 @SiO 2 hollow nanospheres via the template etching.…”

“…In addition, the good micro-topography is an effective strategy for enhancing catalytic activities, − such as Nada et al have used the TiO 2 nano-tree for improving the photo-electrocatalytic H 2 production .
