“…Due to the unique properties of the GDY materials and their composites (e.g., high electrical conductivities, large specific surface areas, unique and uniformly distributed pores, strong interactions toward the analytes, promoted ion adsorption/diffusion), [75,125,209] they are conducive to the pre-enrichment of detected substances in the electrochemical detection processes. [210,211] Therefore, the GDY materials and their composites have been employed to monitor various analytes, such as environmental pollutants [34,212,213] and biomolecules. [214][215][216][217][218] A series of GDY materials and their composites, including GDY, GDY oxides (GDYO), and reduced GDYO materials have been synthesized by means of chemical (cr-GDYO) and electrochemical approaches (er-GDYO).…”

Graphdiyne, a carbon allotrope, was synthesized in 2010 for the first time. It consists of two acetylene bonds between adjacent benzene rings. Graphdiyne and its composites thus exhibit ultrahigh intrinsic electrochemical activities. As “star” electrode materials, they have been utilized for various electrochemical applications. With the aim of giving a full screen of graphdiyne electrochemistry, this review starts from the history of graphdiyne materials, followed by their structural and electrochemical features. Recent progress and achievements in the synthesis of graphdiyne materials and their composites are overviewed. Subsequently, various electrochemical applications of graphdiyne materials and their composites are summarized, covering those in the fields of electrochemical energy conversion, electrochemical energy storage, and electrochemical sensing. The perspectives of graphdiyne electrochemistry are also discussed and outlined.

“…In recent years, graphdiyne (GDY), a two‐dimensional carbon allotrope, has emerged as a potential material in solar cells and semiconductors owing to its excellent conductivity, good electron‐transfer ability, and highly π‐conjugated structure [181] . Zhang and his colleagues [181] used GDYO, the oxidized form of GDY, to prepare a dihydroxybenzene sensor. The sensor's recognition sensitivity towards dihydroxybenzene was improved due to the presence of a pore on the surface of GDYO.…”

Dihydroxybenzene is regarded as a serious environmental pollutant. Its detection through electrochemical methods is still challenging due to having a similar structure and overlapping signals with the conventional bare electrode. Thanks to the unique features and wide applicability of carbon nanotubes, graphene, and their derivatives, they can be used as modifiers to overcome the poor resolution ability of bare electrodes in the detection of dihydroxybenzene. This review focuses on the use of carbon nanotubes, graphene, and their derivatives and nanocomposites to enhance the electrocatalytic activity of conventional bare electrodes for dihydroxybenzene sensing. The reports from 2011–2020 on the simultaneous and/or individual detection of three different dihydroxybenzenes – hydroquinone, catechol, and resorcinol – are summarized. This review also highlights the challenges and prospects surrounding the sensitive and selective detection of dihydroxybenzene.

“…Benefiting from unique structure and properties, graphenebased devices have been applied for fast and cheap DNA sequencing technology. The density functional theory calculation indicated that the interaction between GDY and 6-carboxyfluorescein(FAM) was stronger than that of other 2D nanomaterials, such as graphene [85] , confirming that the presence of acetylene in GDY facilitated the single-stranded DNA(ssDNA) adsorption, which led to a further increase of fluorescence quenching [54,83] . In addition, GDY was used as a support material for immobilizing enzymes to target biomolecules, thereby improving the selectivity of electrochemical biosensors [84] .…”
