“…Such materials have relevance to transistor (opto)electronics, hence various interfaces are formed via non-colloidal methods. 180 The strong van der Waals (vdW) interactions between 2D layered materials such as graphene, 181,182 phosphorene, 183,184 transition metal dichalcogenides (TMDC), 185,186 graphitic carbon nitride, 187,188 and hexagonal boron nitride (h-BN) 189 allow numerous opportunities to interface 2D-2D materials. The vdW interactions are a fascinating synthetic approach as it can direct the integration of mixed dimensionalities ranging from 0D to 3D complex structures into a variety of devices and architectures.…”

“…180,190 In the colloidal synthetic realm, usually an exfoliation step is required before interfacing with metals, 191 metal cations (which may transform the 2D substrate, see Fig. 8a-c) 184 or other material classes. We refer the reader to a review by Dubertret and co-workers on 2D colloidal nanocrystals.…”

Ultrathin two‐dimensional catalysts are attracting attention in the field of electrocatalytic hydrogen evolution. This work describe a composite material design in which CoP nanoparticles doped with Ru single‐atom sites supported on carbon dots (CDs) single‐layer nanosheets formed by splicing CDs (Ru1CoP/CDs). Small CD fragments bore abundant functional groups, analogous to pieces of a jigsaw puzzle, and could provide a high density of binding sites to immobilize Ru1CoP. The single‐particle‐thick nanosheets formed by splicing CDs acted as supports, which improved the conductivity of the electrocatalyst and the stability of the catalyst during operation. The Ru1CoP/CDs formed from doping atomic Ru dispersed on CoP showed very high efficiency for the hydrogen evolution reaction (HER) over a wide pH range. The catalyst prepared under optimized conditions displayed outstanding stability and activity: the overpotential for the HER at a current density of 10 mA cm−2 was as low as 51 and 49 mV under alkaline and acidic conditions, respectively. Density functional theory calculations showed that the substituted Ru single atoms lowered the proton‐coupled electron transfer energy barrier and promoted H−H bond formation, thereby enhancing catalytic performance for the HER. The findings open a new avenue for developing carbon‐based hybridization materials with integrated electrocatalytic performance for water splitting.
