Interface engineering has been proven a powerful tool to improve performances of the perovskite solar cells (PSCs). Herein, highly π-conjugated graphdiyne (GDY) is employed as an interface linker between film and hole transport layer (HTL). It found that GDY can significantly suppress formation metallic Pb (a detrimental defect), reduces carrier recombination. The also form π-π stacking interac...

Herein, pyridinic nitrogen substituted graphdiyne (PyN-GDY) is directly prepared on the surface of copper foil via a facile Glaser-Hay reaction. PyN-GDY comprises GDY-like hybridized sp2 and sp-carbon structures, meanwhile one C atom in benzene ring replaced by pyridinic-N atom. Hence, lithium (Li) atoms intercalated into framework can be stabilized due to interaction between Li pyridinic-N, wh...

Abstract Selective and efficient ammonia (NH 3 ) production using an electrocatalytic nitrate reduction reaction (ECNtRR) under ambient conditions provides a green promising alternative to the traditional energy-intensive Haber–Bosch process. The challenge is in design controlled syntheses of electrocatalysts with high selectivities, NH yield rates (Y NH3 long-term stabilities. Here, freestandi...

Though the gas sensing applications of graphdiyne have widely reported; however, biosensing utility needs to be explored. This study deals with sensitivity nanoflake (GDY) towards uric acid (UA) within density functional framework. The is allowed interact from all possible orientations. Based on these interacting geometries, complexes are differentiated naming, i.e., UA1@GDY, UA2@GDY, UA3@GDY, ...

The graphdiyne (GD), a carbon allotrope with a 2D structure comprising benzene rings and carbon-carbon triple bonds, can be synthesized through cross-coupling on the surface of copper foil. The key problem is in understanding the dependence of layers number and properties, however, the controlled growth of the layers numbers of GD film have not been demonstrated, its controlled growth into larg...
