A review on photo-, electro- and photoelectro- catalytic strategies for selective oxidation of alcohols

The mechanistic diversity of the selective aerobic oxidation of alcohols catalyzed by systems derived from CuI and a diamine ligand

“…The oxidation of alcohols to aldehydes is a reaction under continuous investigation due to its importance in synthetic chemistry in both the laboratory and industry. With increasing concern regarding environmental issues, more sustainable approaches, particularly those employing catalytic routes such as cheap-metal based catalysis 1,2 and photocatalysis, [3][4][5] for the conversion are highly desirable compared to the traditional ones. 6,7 Whether a process is environmentally benign or not depends largely on the usage of catalysts, oxidants and reaction conditions (temperature and reaction media).…”

Activation of DMSO(-d6) via heterogeneous photo-Fenton-like process with in situ production of hydroxyl radicals for the C–H (trideutero)methylation of (iso)quinoliniums

“…Based on the control experiments and literature reports, 1,10,22 a plausible reaction mechanism is proposed in Scheme 3. Initially, the photogenerated electron–hole pairs of gCN/MnO/MnO(OH) are effectively separated upon light illumination.…”

“…Initially, the photogenerated electron–hole pairs of gCN/MnO/MnO(OH) are effectively separated upon light illumination. 22 The photo-generated electrons accumulated on the CB of the photocatalyst activate O 2 to superoxide radical anions (O 2 ˙ − ). Alternatively, the photogenerated hole (h + ) of the photocatalyst undergoes a single electron oxidation process with water to produce H 2 O 2 .…”

“…Afterwards, the reaction between the nucleophilic ˙CH 3 -radicals and the most-electrophilic carbon of (iso)quinoliniums ( 1 ) provides the desired product 2 . 22 Throughout the procedure, O 2 is converted to H 2 O 2 (Scheme 3). The same mechanism is applicable for the trideuteromethylation of (iso)quinoliniums (Table 3); however, in this instance, ˙CD 3 -radicals will be produced from DMSO-d 6 .…”

CaIn2S4–In2O3 hybrid nanofibers with expedited photocarrier separation for fast photocatalytic bacterial inactivation under visible light

“…which directly kill various microbes. [23][24][25] Whereas photocatalytic disinfection has been widely investigated over TiO 2 and the compounds containing precious metals (e.g. AgInS 2 , AgBr, AgVO 3 , etc.…”
