The excellent photocatalytic NO removal performance relates to the synergistic effect between the prepositive NaOH solution and the g-C3N4 photocatalysis

Crystal phase engineering SiC nanosheets for enhancing photocatalytic CO2 reduction

“…The construction of a stable heterojunction interface is the key 21,22 , which is related to the lattice matched heterointerfaces and prepared methods. Traditional methods mostly combine the two materials by electrostatic force 23,24 , but it is difficult to achieve the optimal contact effect, and the separation between the two materials may occur with the pH of the environment changes [25][26][27] . Compared with heterogeneous junctions constructed using different semiconductors, heterophase junctions are more efficient because they have the same chemical composition and a good lattice matching to construct a more desirable interface and thus facilitate carrier migration at the interfaces more efficiently 28,29 .…”

In situ preparation of a Bi2O2CO3/BiOI with 2D/2D p-n heterojunction photocatalyst for water purification under visible light

“…However, Bi 2 O 2 CO 3 ’s wide band gap (2.87–3.58eV) can only be activated under UV irradiation ( Zu et al, 2021 ), and the narrow band gap of BiOI (1.73–1.92eV) also greatly limits its further development in the degradation of organic pollutants ( Lu et al, 2021 ). Considering that BiOI and Bi 2 O 2 CO 3 have similar crystal structures and matched energy levels, a coupled heterojunction can be formed at an interface between them which may allow response to visible light, improving the effective separation of light-induced electron-hole pairs, improving the adsorption dyestuffs ( Qi et al, 2022 ), and achieving efficient decomposition of organic compounds ( Chen et al, 2022 ).…”

MoSx/ZnS on CuO/Cu Mesh Composite Catalyst for Enhanced Photocatalytic N2 Reduction

“…Afterward, the interest in TiO 2 photocatalysis has been growing in the academic and industrial fields. Also, several attempts at modification of TiO 2 for photocatalysis have been reported. − Photocatalysis, as a new catalytic method, has been widely used in water splitting hydrogen, − CO 2 reduction, − N 2 reduction, − pollutant degradation, − and other fields . Photocatalytic is also a potential strategy for ammonia synthesis, with solar energy as the driving force and H 2 O as the proton source.…”
