“…1A . The rigid plane of TP ( 28 , 29 ) and the stable triangular pyramidal structure of TPP ( 30 ) make them difficult to change the conformations as responded to the electric field. On the contrary, the chemical nature of TPA allows the fabrication of a responsive switch under the electric field.…”

Single-molecule electronics offer a unique strategy for the miniaturization of electronic devices. However, the existing experiments are limited to the conventional molecular junctions, where a molecule anchors to the electrode pair with linkers. With such a rod-like configuration, the minimum size of the device is defined by the length of the molecule. Here, by incorporating a single molecule with two single-layer graphene electrodes, we fabricated layer-by-layer single-molecule heterojunctions called single-molecule two-dimensional van der Waals heterojunctions (M-2D-vdWHs), of which the sizes are defined by the thickness of the molecule. We controlled the conformation of the M-2D-vdWHs and the cross-plane charge transport through them with the applied electric field and established that they can serve as reversible switches. Our results demonstrate that the M-2D-vdWHs, as stacked from single-layer 2D materials and a single molecule, can respond to electric field stimulus, which promises a diverse class of single-molecule devices with unprecedented size.

“…In the synthesis procedure, the evolved PH 3 gas by the decomposition of NaH 2 PO 2 at lower temperatures (≥300 °C) firstly reacted with partial NiCl 2 ·6H 2 O to form Ni 3 P nanoparticles. 39 As the calcination temperature increased up to ∼500 °C, the remaining Ni species and dicyandiamide (DCD) were pyrolyzed and transformed into the Ni–C 3 N 4 material 40 and subsequently converted into Ni nanoparticles at 700 °C, in turn triggering the generation of N-doped carbon nanofibers, which could serve as an ideal carrier for the effective immobilization of nanoparticles. 41,42 Eventually, Ni 3 P and Ni nanoparticles were co-anchored in the carbon nanofibers, and a tightly bound heterogeneous structure was formed between them, resulting in N-doped carbon nanofiber-supported heterogeneous Ni 3 P/Ni nanoparticles (denoted hereafter as Ni 3 P/Ni@N-CNFs).…”

“…153 So far, a Ptbased catalyst is still the state-of-the-art HER catalyst in both acidic and alkaline conditions. 95,154 Nonprecious-metal-based HER catalyst research has also made significant achievements, with several metal sulfides, phosphides, 155,156 and selenides such as MoS 2 , 157 CoP, 158 and WSe 2 active in acidic conditions and Ni-based catalysts functional in alkaline conditions. 159,160 Like OER, bioderived materials can be used to facilitate electron transfer and proton diffusion for HER.…”

The development of efficient and sustainable electrochemical systems able to provide clean-energy fuels and chemicals is one of the main current challenges of materials science and engineering. Over the last decades, significant advances have been made in the development of robust electrocatalysts for different reactions, with fundamental insights from both computational and experimental work. Some of the most promising systems in the literature are based on expensive and scarce platinum-group metals; however, natural enzymes show the highest per-site catalytic activities, while their active sites are based exclusively on earth-abundant metals. Additionally, natural biomass provides a valuable feedstock for producing advanced carbonaceous materials with porous hierarchical structures. Utilizing resources and design inspiration from nature can help create more sustainable and cost-effective strategies for manufacturing cost-effective, sustainable, and robust electrochemical materials and devices. This review spans from materials to device engineering; we initially discuss the design of carbon-based materials with bioinspired features (such as enzyme active sites), the utilization of biomass resources to construct tailored carbon materials, and their activity in aqueous electrocatalysis for water splitting, oxygen reduction, and CO 2 reduction. We then delve in the applicability of bioinspired features in electrochemical devices, such as the engineering of bioinspired mass transport and electrode interfaces. Finally, we address remaining challenges, such as the stability of bioinspired active sites or the activity of metal-free carbon materials, and discuss new potential research directions that can open the gates to the implementation of bioinspired sustainable materials in electrochemical devices.
