“…Other authors report that the oxidation of BP flakes leads to a decrease of the humidity sensing response of the BP-based sensors. Miao et al [ 220 ], for example, have fabricated a transistor with a mechanically exfoliated flake as sensing material. In order to avoid the degradation of the BP flakes, a 6 nm thick Al 2 O 3 layer has been deposited on the BP flakes and its sensing and conductivity properties have been compared with the ones of a not-capped BP flake.…”

After the synthesis of graphene, in the first year of this century, a wide research field on two-dimensional materials opens. 2D materials are characterized by an intrinsic high surface to volume ratio, due to their heights of few atoms, and, differently from graphene, which is a semimetal with zero or near zero bandgap, they usually have a semiconductive nature. These two characteristics make them promising candidate for a new generation of gas sensing devices. Graphene oxide, being an intermediate product of graphene fabrication, has been the first graphene-like material studied and used to detect target gases, followed by MoS2, in the first years of 2010s. Along with MoS2, which is now experiencing a new birth, after its use as a lubricant, other sulfides and selenides (like WS2, WSe2, MoSe2, etc.) have been used for the fabrication of nanoelectronic devices and for gas sensing applications. All these materials show a bandgap, tunable with the number of layers. On the other hand, 2D materials constituted by one atomic species have been synthetized, like phosphorene (one layer of black phosphorous), germanene (one atom thick layer of germanium) and silicone (one atom thick layer of silicon). In this paper, a comprehensive review of 2D materials-based gas sensor is reported, mainly focused on the recent developments of graphene oxide, exfoliated MoS2 and WS2 and phosphorene, for gas detection applications. We will report on their use as sensitive materials for conductometric, capacitive and optical gas sensors, the state of the art and future perspectives.

“…In addition to h‐BN nanosheets, the ultrathin conventional dielectric oxides, such as SiO 2 or Al 2 O 3 , can be applied to package the sensitive BP nanosheets as well as improving the performance of the corresponding devices . Recently, a heterostructure of phosphorene sandwiched between two SiO 2 films has been designed and shown arresting stability in ambient for months ( Figure a) .…”

The rise of 2D layered materials has inspired luxuriant research interests in the development of novel nanodevices. Thanks to van der Waals interlayer forces and being free of dangling surface bonds, 2D materials are favorable for constructing vertical heterostructures by combining materials with different features. In recent years, ultrathin black phosphorus (BP) has been rediscovered as a new member of the 2D family and is attracting significant research attention due to its outstanding electronic properties and tunable bandgaps, which offers a new avenue for the creation of novel 2D heterostructures. Here, the recent development of heterostructured architectures based on 2D BP nanosheets is summarized with an emphasis on device characterizations. Stacks of phosphorene with graphene, semiconductors, or insulators are reviewed, along with methods to characterize the corresponding proof‐of‐concept devices, as well as potential opportunities for applications in the 2D limit, including transistors, optoelectronic devices, and sensors, with unprecedented functionalities. Finally, the challenges ahead of BP heterostructures are discussed and some future outlooks are suggested.

Black phosphorus (BP) is rediscovered as a 2D layered material. Since its first isolation in 2014, 2D BP has triggered tremendous interest in the fields of condensed matter physics, chemistry, and materials science. Given its unique puckered monolayer geometry, 2D BP displays many unprecedented properties and is being explored for use in numerous applications. The flexibility, large surface area, and good electric conductivity of 2D BP make it a promising electrode material for electrochemical energy storage devices (EESDs). Here, the experimental and theoretical progress of 2D BP is presented on the basis of its preparation methods. The structural and physiochemical properties, air instability, passivation, and EESD applications of 2D BP are discussed systemically. Specifically, the latest research findings on utilizing 2D BP in EESDs, such as lithium‐ion batteries, supercapacitors, and emerging technologies (lithium–sulfur batteries, magnesium‐ion batteries, and sodium‐ion batteries), are summarized. On the basis of the current progress, a few personal perspectives on the existing challenges and future research directions in this developing field are provided.
