Solid-Supported Heterogenized Palladium Nanoparticles: Propitious Vehicles for Sonogashira Cross-Coupling Reaction

“…Nanoparticles with controlled compositions, uniform and low particle sizes, high number of surface atoms, large surface area, shape selectivity, zeta potential values, and superior surface chemistry exhibit tailorable catalytic properties and selectivity 6 . Selection of a suitable solid support for nanocatalysts is critical as it not only controls the shape, size, and distribution of NPs on its surface but also eases a cooperative and efficient pathway to achieve the target product through strong metal-support interaction (SMSI), high surface area, a substantial number of participating active sites, increased stability, decreased leaching and agglomeration of metal nanoparticles and increased recyclability 7,8 . Solid support heterogenized Pd nanoparticles are now being explored as useful catalysts for Sonogashira, Heck, Suzuki Miyaura and several other C-C cross-coupling reactions 9,10,11 .…”

“…Solid support heterogenized Pd nanoparticles are now being explored as useful catalysts for Sonogashira, Heck, Suzuki Miyaura and several other C-C cross-coupling reactions 9,10,11 . The recent reports on the synthesis of heterogenized Pd nanoparticles with controlled shapes, sizes, detailed structures, and choice of a plethora of nanostructured solid supports has led to meaningful progression in the field [8][9][10][11] . This spotlight article lists some examples of solid supports used for tailoring Pd nanoparticles (Figure 1, Table 1), and their catalytic application in Sonogashira cross-coupling reaction (Table 1).…”

Recent Advances on g‐C3N4 Based Photocatalysts for Typical Antibiotics Photodegradation: Preparation, Mechanism and Influencing Factors

“…Recently, the bulk g-C 3 N 4 was exfoliated into nanosheet-like 2D g-C 3 N 4 nanosheets by solution ultrasonication or acid-base etching, featuring adjustable electronic structure, reliable stability, and fast electrical charge transfer, and could dramatically accelerate the separation of optical excitation electron-hole pairs, so as to overcome the photo corrosion phenomenon. [117] Meanwhile with a bigger specific surface area, the bulk g-C 3 N 4 providing more active centers and a shorter carrier path length, which has better photocatalytic performance. [118] Yin et al obtained a 2D/ 2D P-g-C 3 N 4 /Bi 2 WO 6 catalyst prepared with a combination of phosphorus doping and morphology control.…”
