“…23,27 In the Raman spectra of GDY/G, the peaks located at 1359 and 1599 cm −1 are graphene lattice vibrations, and 2122 cm −1 can be attributed to the C�C bond vibrations of GDY. 23,28 3.2. Electrochemical Characterization of Modified Electrodes.…”

“…Figure m shows the Raman spectra of graphene and GDY/G. In the Raman spectra of graphene, the peaks located at 1348 and 1601 cm –1 correspond to the D- and G-bands, respectively. , In the Raman spectra of GDY/G, the peaks located at 1359 and 1599 cm –1 are graphene lattice vibrations, and 2122 cm –1 can be attributed to the CC bond vibrations of GDY. , …”

“…GDY/G was synthesized from our previous work. 23 Tetrabutylammonium fluoride (1 M in THF, 1 mL) was added into a solution of 100 mg of hexakis[(trimethylsilyl)-ethynyl]benzene (HEB−TMS) and 40 mL of dichloromethane (DCM) and stirred at 0 °C for 15 min. Then, the mixture was washed with deionized water, dried by anhydrous MgSO 4 , and filtered.…”

Graphdiyne Electrochemistry: Progress and Perspectives

“…The pores on the GDY plane are conducive to O 2 adsorption. [183] For example, a Cu 3 Pd nanoalloy that was in situ grown or tightly anchored on a hydrogen-substituted GDY (GDY/Cu 3 Pd) exhibited a reduced ORR onset potential and a larger peak current density in both O 2 -and N 2 -saturated KOH solutions, when compared with the Cu 3 Pd nano-alloy that was loaded on the reduced graphene oxide (rGO) or a GDY material without the loading of the Cu 3 Pd nanoalloy. [147] Such improved ORR performance was explained by a strong interaction between the GDY/Cu 3 Pd electrocatalyst and oxygen, stemming from a strong metal chelating ability between the acetylene bonds on the GDY and the Cu 3 Pd nano-alloy.…”

Plasma-modified graphitic C3N4@Cobalt hydroxide nanowires as a highly efficient electrocatalyst for oxygen evolution reaction

“…Hence, there is a need to synthesize hybrid materials containing g-C 3 N 4 that can improve the catalytic activity of g-C 3 N 4 for OER [ 16 , 17 ]. Transition metal materials and their layered double hydroxides [ 18 ], oxides [ 19 , 20 ], perovskites [ 21 , 22 ], phosphides [ 23 , 24 ], sulfides [ 25 , 26 ], and nitrides [ 27 ], have been extensively investigated over the last decades, and many of them exhibit significant electrocatalytic activity toward OER. Co-based catalysts have been chosen over other non-precious transition metal-based catalysts owing to their availability and inexpensive cost.…”
