“…Three well-defined stages can be identified during this process: alloying, crystal nucleation, and axial growth. , From the viewpoint of growth kinetics, the VLS mechanism emphasizes that surface diffusion of reactant species and their preferential incorporation at high-surface-energy sites Figure a shows a scheme of the on-substrate growth of CdSe NWs, using Au nanoparticles as the catalyst . At the initial stage of the reaction, Ar+H 2 gas carried the CdSe vapor into the liquid Au nanoparticles, followed by the dissolution of CdSe in Au particles.…”

The unique electronic and catalytic properties emerging from low symmetry anisotropic (1D and 2D) metal chalcogenides (MCs) have generated tremendous interest for use in next generation electronics, optoelectronics, electrochemical energy storage devices, and chemical sensing devices. Despite many proof-of-concept demonstrations so far, the full potential of anisotropic chalcogenides has yet to be investigated. This article provides a comprehensive overview of the recent progress made in the synthesis, mechanistic understanding, property modulation strategies, and applications of the anisotropic chalcogenides. It begins with an introduction to the basic crystal structures, and then the unique physical and chemical properties of 1D and 2D MCs. Controlled synthetic routes for anisotropic MC crystals are summarized with example advances in the solution-phase synthesis, vapor-phase synthesis, and exfoliation. Several important approaches to modulate dimensions, phases, compositions, defects, and heterostructures of anisotropic MCs are discussed. Recent significant advances in applications are highlighted for electronics, optoelectronic devices, catalysts, batteries, supercapacitors, sensing platforms, and thermoelectric devices. The article ends with prospects for future opportunities and challenges to be addressed in the academic research and practical engineering of anisotropic MCs.

“…As a well‐known method for synthesis of 1D NWs, VLS growth has been proposed and demonstrated for facile technique to obtain NWs such as Si NWs, ZnO NWs, CdSe NWs, and GaN NWs . Hierarchical structure of ZnO NFs with SnO 2 NW branches was also demonstrated as sensing layer for the detection of nitrogen dioxide (NO 2 ) using electrospinning technique combined with VLS growth .…”

Chemical sensors have been essential components in recent years due to the gathering attention in environmental monitoring and healthcare. In this review, the authors comprehensively highlight recent progresses on the 1D chemiresistive-type sensors based on semiconductor metal oxides (SMOs) and optical-type sensors, which are prepared by electrospinning technique. In the part of chemiresistive-type sensors, diverse synthesis techniques for 1D SMO nanofibrous structure are presented with controlled microstructure and surface morphology. In addition, unique functionalization routes of emerging nanocatalysts encapsulated by bio-inspired templates are described for the next generation catalyst on the 1D SMO nanofibers (NFs). For the optical-type sensors, new classes of 1D NFs employing specific absorption and emission properties are introduced. In particular, diverse 1D NF-based colorimetric and fluorescence sensors as well as Raman and surface-enhanced Raman scattering sensors are covered in the view point of material preparation and optical sensing properties. Finally, the authors prospect future research directions to overcome current limitations and challenges to achieve high performance chemical sensors.

“…Vapor phase growth is a well-adopted method to fabricate nanowires, formed by condensation of vaporized sources. Various vapor phase growth techniques have been developed to fabricate cadmium chalcogenides nanowires, including chemical vapor deposition (CVD) [70][71][72][73][74][75][76][77][78][79] , metal-organic chemical vapor deposition (MOCVD) [80,81] , physical vapor deposition (PVD) [82] , pulse laser deposition (PLD) [83] , molecular beam epitaxial (MBE) [84] , etc. In general, the vapor phase growth of nanowires is governed by two different growth mechanisms: vapor-liquid-solid (VLS) and vapor-solid (VS).…”
