Emerging applications of nanodiamonds in photocatalysis

Abstract

as a fascinating nanocarbon photocatalytic material, nanodiamonds (NDs) have attracted more and more attention recently due to their high chemical stability, high carrier mobility, narrowing band gap, easy surface modification, and mass production. this review summarizes the latest progress related to elaborated construction of NDs and NDs-based nanocomposite, including microstructure regulation of pristine NDs, elemental doping and formation a heterojunction by coupled with another semiconductor. the construction and properties of each category of NDs-based material are reviewed on their structure, preparation methods, texture control, and photocatalytic performance. Photocatalytic applications of NDs-based nanomaterials for hydrogen evolution from water splitting, organic pollution degradation, cO 2 reduction, N 2 reduction, graphene oxide reduction, and the latest advances in photocatalytic reaction mechanism have been also systematically reviewed. Finally, the challenges and prospects of the photocatalytic application of NDs are also briefly analyzed.

Enhanced thermally stable performance of Pr3+-doped vanadate phosphor by inhibiting the intervalence charge transfer quenching channel

“…New rare earth luminescent materials have been extensively used in lighting equipment, screen displays, and temperaturesensitive measurements due to their high efficiency, longevity, and high purity. [1][2][3][4][5][6][7][8][9][10][11][12][13] Pr 3+ is often doped with oxide crystals as an optical material because its energy level structure allows linear and nonlinear effects. [14][15][16] Moreover, due to the electron transfer between different metal ions, the trivalent Pr 3+ ion can undergo metal-to-metal charge transfer with transition metal ions (Mn + ), forming a low-location charge transfer state, i.e., intervalence charge transfer (IVCT).…”

Superhydrophobic Nanodiamond-Functionalized Melamine Sponge for Oil/Water Separation

“…26 exploring a nanostructure with a large specific surface area and a high superhydrophobic/superoleophilic surface is a critical step. As a carbon-based material, nanodiamonds (NDs) are widely used in precision processing, 27 electronic devices, 28 sensors, 29,30 and other fields 31 due to their low cost, large-scale production, large specific surface area, rich surface chemistry, and high hardness. When it comes to oil-stained adsorption materials, ND powders have many advantages.…”

Transitions in polycrystalline diamond probed by steady state, modulated and transient surface photovoltage spectroscopy

“…Due to its unique properties as a semiconductor with an ultrawide bandgap (indirect bandgap of 5.47 eV [1]), diamond has a great potential for emerging applications in electronics [2,3], optoelectronics [4], bio sensors [5], spintronics [6,7], photocatalysis [8] and so on.
