Self-Assembly of CdS/CdIn2S4 Heterostructure with Enhanced Photocascade Synthesis of Schiff Base Compounds in an Aromatic Alcohols and Nitrobenzene System with Visible Light

“…Unfortunately, there are several drawbacks, such as toxicity, causticity, and release of large amounts of heavy-metal waste in this reaction system, which greatly restrict their large-scale applications. − Therefore, an efficient and sustainable photocatalytic technology based on the semiconductor materials has been developed. Up to now, all kinds of semiconductor photocatalysts, such as TiO 2 , M/TiO 2 (M = noble metal), dye-sensitized TiO 2 and 2, 2, 6, 6-tetramethypiperdinyloxyl, CdS, and CdMS (M = In, Zn, La), have been developed extensively for photocatalytic production of aromatic aldehydes from the corresponding alcohols under mild conditions. − Meanwhile, aniline is also a potential intermediate in industrial synthesis of fine chemicals, dyes, pesticides, and pharmaceuticals. , Generally, the partial reduction of nitrobenzene to aniline is carried out by means of a hydrogenation reaction. − Unfortunately, the reaction should be performed in harsh conditions (e.g., high temperature and high pressure of H 2 ). , As a green technology, photocatalytic selective reduction of nitrobenzene to aniline under mild conditions has been published in the last few years. − However, in view of the above photocatalytic oxidation or reduction reactions, the photocatalytic performance still does not meet our expectations, and it requires electron or hole capturers in the reaction systems. Thence, we urgently need to construct a photocatalytic system that can simultaneously utilize photoinduced charge carriers for photocatalytic selective redox reactions of organic matters.…”

A Novel CdS/g‐C3N4 Composite Photocatalyst: Preparation, Characterization and Photocatalytic Performance with Different Reaction Solvents under Visible Light Irradiation

“…In principle, when the conduction band (CB) potential of a photocatalyst is lower than 0.486 eV, the formation of aniline can be achieved from nitrobenzene via photocatalysis technology. [38] As we all know, •O 2  and h ＋ are important oxidants for selective oxidation of aromatic alcohols to corresponding aldehydes, and photo-induced electrons are important reducers for reduction of nitrobenzene into aniline. Thus, constructing a novel narrow band gap hybrid photocatalyst with more negative CB values and appropriate VB position may realize simultaneously the selective oxidation of aromatic alcohols to corresponding aldehydes, as well as the reduction of nitrobenzene into aniline in a reaction system.…”

Ultrathin ZnTi-LDH nanosheet: A bifunctional Lewis and Brönsted acid photocatalyst for synthesis of N-benzylideneanilline via a tandem reaction

“…Band positions of the samples, redox potentials of nitrobenzene (NB), benzyl alcohol (BA) and benzaldehyde (BAD) are shown in Scheme 2. The CB potentials of ZT-1 and ZT-2 are more negative than the redox potential (-0.49 V vs. NHE) of NB to aniline (AL) [44], indicating that ZT-1 and ZT-2 have thermodynamic feasibility for the reduction of NB to AL. Moreover, the VB potentials of them are between the redox potential of BA to BAD (1.98 V vs. NHE) and the redox potential (2.50 V vs. NHE) of BAD to oxidized BAD [45], suggesting that both of them are thermodynamically permissible for the selective oxidation of BA to BAD.…”
