2D/2D Heterojunctions for Catalysis

Advanced Science, Год журнала: 2019, Номер 6(7)

Опубликована: Янв. 30, 2019

2D layered materials with atomic thickness have attracted extensive research interest due to their unique physicochemical and electronic properties, which are usually very different from those of bulk counterparts. Heterojunctions or heterostructures based on ultrathin increasing attention the integrated merits components heterojunction effect separation transfer charges, resulting in important potential values for catalytic applications. Furthermore, 2D/2D face-to-face contact believed be a preferable dimensionality design large interface area, would contribute enhanced effect. Here, cutting-edge progress heterojunctions is highlighted specific emphasis synthetic strategies, reaction mechanism, applications catalysis (photocatalysis, electrocatalysis, organic synthesis). Finally, key issues development perspectives also discussed.

Heterogeneous Photocatalytic Organic Transformation Reactions Using Conjugated Polymers-Based Materials

ACS Catalysis, Год журнала: 2020, Номер 10(20), С. 12256 - 12283

Опубликована: Сен. 24, 2020

Photocatalytic heterogeneous organic transformation is considered as an efficient, clean atomic economy, and low-energy consumption strategy for synthesis. Conjugated polymers (CPs)-based materials have recently shown great potential diverse photocatalytic applications because of their unique properties, such structural designability, recyclability, high chemical stability, low cost, they emerged promising alternatives to traditional molecular or inorganic photocatalyst in photoredox reactions. Immense efforts been made toward the construction CPs-based versatile transformations. In this Review, we aim summarize recent progress photocatalysts transformations including oxidation, reduction, coupling, cycloaddition reaction. This Review discusses influence molecular, electronic, channel structure on light absorption, charge separation, mass transfer different The regulated synthesis, mechanistic discussions, future challenges systems are also considered. It expected that could not only deepen comprehension but open up inspirations feasibilities materials.

Selective Activation of Benzyl Alcohol Coupled with Photoelectrochemical Water Oxidation via a Radical Relay Strategy

ACS Catalysis, Год журнала: 2020, Номер 10(9), С. 4906 - 4913

Опубликована: Апрель 1, 2020

Selective oxidation to produce target chemicals usually need activation of O2 at high temperature and/or pressure, which have largely restricted its practical operation and application. Here, we put forward a radical relay strategy coupling photoelectrochemical (PEC) water toward efficiently selective conversion benzyl alcohol (BA) benzaldehyde (BAD). An illuminated BiVO4 (BVO) photoanode covered with an ultrathin (∼3 nm) hydrothermally synthesized layered double hydroxide (U-LDH) catalyst graphene (G) exhibited >99% selectivity BAD (1.2 V vs. RHE). Mechanistic studies DFT calculation verified that the hydroxyl radicals (·OH) generated from are bound surface U-LDH through hydrogen-bonding interactions energy is lowered. Fourier transform infrared spectroscopy showed BA adsorbed catalyst, but not. Thus, favored not only by controlled capacity ·OH desorption desired product before further occurs. This work introduces alternative PEC way achieve mild derivatives based on ternary G@U-LDH@BVO catalysts.
