Probing the mechanism of benzaldehyde reduction to chiral hydrobenzoin on the CNT surface under near-UV light irradiation

Abstract

For the first time, metal-free CNTs is found to be an effective photocatalyst working under near-UV light (400 nm).

Coupling Strategy for CO2Valorization Integrated with Organic Synthesis by Heterogeneous Photocatalysis

“…Theunderlying reaction mechanisms for the oxidation of BA and reduction of CO 2 on the corresponding components, Bi 2 WO 6 and FAPbBr 3 ,respectively,was examined in detail by density functional theory (DFT) calculations.Inthe oxidation reaction, the results showed that BA is first spontaneously adsorbed on the surface of Bi 2 WO 6 .N ext, the OH group of BA is deprotonated, and then one of the HÀCb onds in the methyl group is broken, and finally BD is formed through the continuous dehydrogenation process (Figure 14 Apart from BD,the CÀCcoupled products of BA,such as hydrobenzoin (HB) and benzoin (BZ), have been frequently used in synthetic chemistry,a si mportant pharmaceutical intermediates and structural motifs in natural products. [60,63] To this end, we developed ad ual-functional reaction system that realized the efficient reduction of CO 2 to CO coupled with selective conversion of BA to valuable CÀCc oupled products,b ased on ZnIn 2 S 4 (ZIS) materials that is functionalized by the surfactant cetyltrimethylammonium bromide (CTAB). [64] In contrast to pristine ZIS,CTAB-ZIS presented largely enhanced photoactivity in this dual-functional reaction system.…”

“…Apart from BD, the C−C coupled products of BA, such as hydrobenzoin (HB) and benzoin (BZ), have been frequently used in synthetic chemistry, as important pharmaceutical intermediates and structural motifs in natural products [60, 63] . To this end, we developed a dual‐functional reaction system that realized the efficient reduction of CO 2 to CO coupled with selective conversion of BA to valuable C−C coupled products, based on ZnIn 2 S 4 (ZIS) materials that is functionalized by the surfactant cetyltrimethylammonium bromide (CTAB) [64] .…”

Mechanical Properties of Disconnected Multiwalled Carbon Nanotubes and Carbon Nanotube Composites - A Review Paper

“…To the best of our insight, no investigation has been performed on the waviness of CNTs in composites within the sight of Van der Waals interphase districts. One of the primary downsides of most investigations on foreseeing the mechanical properties of CNT composites is the immediate utilization of the micromechanics conditions reasonable for stringy composites [67,86,90,92,96,97,101,107]. In particular, they supplant the cross section structure of a CNT with a strong fibre.…”
