“…In 2015, Erande et al carried out the electrochemical exfoliation of bulk BP in an aqueous solution of 0.5 m Na 2 SO 4 . The intercalation of sulfate ions led to few‐layer BP sheets with dimensions of 5–10 µm . Similarly, in 2017, Ambrosi et al presented an anodic intercalation method to delaminate bulk BP crystals to few‐layer‐thick BP nanosheets in 0.5 m sulfuric acid .…”

2D materials are important building blocks for the upcoming generation of nanostructured electronics and multifunctional devices due to their distinct chemical and physical characteristics. To this end, large‐scale production of 2D materials with high purity or with specific functionalities represents a key to advancing fundamental studies as well as industrial applications. Among the state‐of‐the‐art synthetic protocols, electrochemical exfoliation of layered materials is a very promising approach that offers high yield, great efficiency, low cost, simple instrumentation, and excellent up‐scalability. Remarkably, playing with electrochemical parameters not only enables tunable material properties but also increases the material diversities from graphene to a wide spectrum of 2D semiconductors. Here, a succinct and critical survey of the recent progress in this research direction is presented, comprising the strategic design, exfoliation principles, underlying mechanisms, processing techniques, and potential applications of 2D materials. At the end of the discussion, the emerging trends, challenges, and opportunities in real practice are also highlighted.

Two‐dimensional (2D) materials are attractive catalysts for the electrochemical reduction of carbon dioxide reaction (eCO2RR) by virtue of their tunable atomic structures, abundant active sites, enhanced conductivity, suitable binding affinity to carbon dioxide and/or reaction intermediates, and intrinsic scalability. Herein, recent advances in 2D catalysts for the eCO2RR are reviewed. Structural features and properties of 2D materials that contribute to their advanced electrocatalytic properties are summarized, and strategies for enhancing their activity and selectivity for the eCO2RR are reviewed. Prospects and challenges of applications of 2D catalysts for the eCO2RR on an industrial scale are highlighted.

Simple Method for Estimating the Surface Area of Layered Graphene‐Based Thin Films

et al. 2019

View full text Add to dashboard Cite

Thin films, papers, or foils produced from graphene‐based materials have been the focus of considerable research interest in recent years. They have a range of applications including energy storage, selective filtration of liquids, and gas storage. For all of these applications, the critical attribute of the films is their pore volume. However, there remains a considerable challenge around characterizing the accessible microscopic surface area of the materials in their intended state of application. In this work, an image‐processing‐based approach is presented for estimating the lower threshold of specific surface area for graphene‐based films that have a typical multilayered structure. Canny edge detection is used together with tortuosity measurements to infer sheet areas from layer edges. The method serves as a simple independent characterization technique. Specific surface area values predicted for a range of similar films vary by less than 4× the reported values, which vary by >1.1×103 in range.
