Environmental applications of single-atom catalysts based on graphdiyne

Abstract

Single-atom catalysts (SACs) have attracted significant attention because of their high atomic efficiency and unique catalytic performance for various catalytic reactions. As a two-dimensional (2D) layered structure, Graphdiyne (GDY) is...

Electroless Deposition of Palladium Nanoparticles on Graphdiyne Boosts Electrochemiluminescence

“…Graphdiyne (GDY), a novel two-dimensional carbon allotrope, contains sp 2 and sp hybridized carbon atoms with highly π–π conjugated structure and electron transfer capability. − The unique alkyne-rich structure and π-electronic structure of GDY essentially make it a promising substrate for anchoring and stabilizing metals or metal oxides with strong d−π interactions. ,− Compared with the conventional catalyst substrates, GDY can significantly improve the catalytic efficiency and durability of catalysts used in redox reactions, electrocatalysis, photocatalysis, and water splitting catalysis. − The alkyne bond in GDY can regulate the electronic properties of loaded metal atoms, thereby improving the catalytic activity. − The strong interaction between metal atoms and GDY results in a uniform distribution and less aggregation of metal particles, leading to the long-term stability of the electrocatalytic reactions. The interfacial interaction between different components is the key factor affecting the catalytic performance, where the electronic metal–support interaction (EMSI) plays an important role in improving the catalytic activity of metal-based catalysts. − EMSI is a bridge between theoretical electronic study and heterogeneous catalyst design.…”

CO2 Photoreduction over Semiconducting 2D Materials with Supported Single Atoms: Recent Progress and Challenges

“…[62] Moreover, this kind of material enables an in-depth understanding of the structure-activity relationship in photocatalysis at the atomic level. Up to the present time, several review articles have covered relevant topics, with some discussing specific types of 2DSemi supporting SAs for CO 2 photoreduction, [63][64][65] others emphasizing surface strategies for catalysts based on 2D materials and SAs, or the coordination chemistry of SAs on 2D materials, [61,66] and a few showcasing examples of SAs-2DSemi for their photocatalytic applications in CO 2 reduction. [61,67] Therefore, an article solely focusing on CO 2 photoreduction over SAs-2DSemi photocatalysts would be particularly apt for researchers in this field to stay updated on recent developments.…”

THD-C Sheet: A Novel Nonbenzenoid Carbon Allotrope with Tetra-, Hexa-, and Dodeca-Membered Rings

“…In such networks, the presence of acetylenic sites (sp bonds) usually results in larger C rings that can successfully be utilized for the adsorption of alkali atoms in alkali-based batteries. Furthermore, these larger rings are suitable to accommodate bigger and heavier metal atoms (mostly transition atoms) to enhance the catalytic activity of such materials. ,, For the same reason, these materials hold promise to be investigated for the storage, capture, and separation of small gas molecules.…”
