Ultralow-temperature assisted synthesis of single platinum atoms anchored on carbon nanotubes for efficiently electrocatalytic acidic hydrogen evolution

Self-healing microcapsules encapsulated with carbon nanotubes for improved thermal and electrical properties

“…In situ polymerization technique is effectively used by researchers for various applications. Zhong et al, 19 have reported a method to anchor atomically dispersed platinum atoms on carbon nano-tubes (Pt-CNT) in an ultra-low temperature solution, to reduce the free energy of Pt atoms in the solution and thus reduce their agglomeration. Xu et al, 20 have fabricated bismuth vanadate (BiVO 4 ) nano-rods by electrospinning and successfully synthesized a core-shell heterojunction by growing molybdenum disulde nano-sheets (MoS 2 ) on (BiVO 4 ) nano-rods by solvo-thermal technique.…”

Designing the future atomic electrocatalyst for efficient energy systems

“…Due to the unique surface structure, preventing the aggregation of metal atoms is the key challenge to synthesize robust and high-performance SAC. Numerous methods have been applied to construct SAC, including the wet-chemistry method, [33][34][35]47 atomic layer deposition (ALD), 48 MOF-derived method, 49 electro-deposition method, 44 atom trapping, [41][42][43] and so on. The representative methods will be briefly introduced in the following sections.…”

“…The rapid developments of synthesis techniques and powerful theoretical modeling have resulted in a variety of systematic approaches to stabilize the single atom sites on the surface via the strong metal-support interaction. 32 Multiple synthesis approaches of SACs have been developed, such as the wet-chemistry approach, [33][34][35] metal-organic frameworks (MOF)-derived methods, [36][37][38][39] pyrolysis, 40 atom trapping, [41][42][43] electrodeposition, 44 impregnation, 45,46 and so on.…”

NiSe2/CdS composite nanoflakes photocatalyst with enhanced activity under visible light

“…In the following decades, people have developed a variety of semiconductor photocatalytic materials, such as oxides, suldes, and oxynitrides. [9][10][11][12][13][14][15][16] The photocatalytic process involves absorbing sunlight to excite photo-generated carriers, diffusion of carriers, and surface reactions. 17 The key problems to be solved in the development of efficient photocatalysts include enhancing light absorption and reducing carrier recombination.…”
