Metallic WO2-decorated g-C3N4 nanosheets as noble-metal-free photocatalysts for efficient photocatalysis

Hollow cubic CuSe@CdS with tunable size for plasmon-induced Vis-NIR driven photocatalytic properties

“…Until all Fermi energy levels are at the same level, the higher Fermi energy levels will shift downward and the comparatively lower Fermi energy levels will shift upward. 38 Because of the positive charge of CdS and the negative charge of CuSe, an internal electric field appears at the contact. Photogenerated carrier separation is primarily driven by the intrinsic interfacial electric field.…”

Unveiling the Bifunctional Photo/Electrocatalytic Activity of In Situ Grown CdSe QDs on g-C3N4 Nanosheet Z-Scheme Heterostructures for Efficient Hydrogen Generation

“…Additionally, its spatial charge density flow and molecular structure have been investigated from computational perspectives . The inability of g-C 3 N 4 -based photocatalysts to respond to visible light and their inability to separate photogenerated carriers limit their solar energy conversion efficiency. , To solve such problems listed above, a lot of work has been done to introduce defects into the g-C 3 N 4 structure through structural engineering, doping with metals, and coupling with other semiconductors. , It has been demonstrated that the adding defects not only provide active sites for photocatalytic reactions but also provide distinct energy levels by regulating band gap engineering. − Additionally, the defects have the ability to remarkably reduce the recombination of electron–hole pairs and serve as trapping sites for photoexcited charge carriers. , Recent research has focused on photo/electrocatalysts with tunable hierarchical quantum dots (QDs)/nanostructures due to their greater surface area, more active sites, and efficient light harvesting for boosting photo/electrocatalytic activity in overall water splitting reactions. Furthermore, QDs can have their chemical compositions and hierarchical structures altered to improve their ability to separate charges and conduct electricity. − …”

Boosted Photocatalytic Degradation of Atrazine Using Oxygen-Modified g-C3N4: Investigation of the Reactive Oxygen Species Interconversion

“…The advanced oxidation process is one of the most widely adopted methods that typically involves the use of expensive oxidants such as hydrogen peroxide (H 2 O 2 ), peroxymonosulfate (PMS), and peroxydisulfate (PDS) . In comparison, photocatalysis has gained significant attention as photocatalysts like titanium dioxide (TiO 2 ), bismuth oxybromide (BiOBr), graphite phase carbon nitride (g-C 3 N 4 ), and covalent organic framework (COF) harness free and inexhaustible solar energy to achieve green and efficient degradation of organic pollutants. − …”
