3D MoS ₂ Aerogel for Ultrasensitive NO ₂ Detection and Its Tunable Sensing Behavior

Journal Article Long, Hu ; Chan, Leslie ; Harley-Trochimczyk, Anna ; ... - Advanced Materials Interfaces

A high-performance NO ₂ sensor based on the 3D MoS ₂ aerogel is introduced. Compared to single- or few-layer MoS2, 3D assemblies of 2D MoS ₂ provide more surface area per footprint with a simple and scalable synthesis. Integration of the 3D MoS ₂ aerogel on a low-power microheater platform is demonstrated, and the sensing behavior of the 3D MoS ₂ aerogel is investigated. A two-step sulfurization treatment is developed to obtain a high-quality MoS ₂ aerogel with strong sensing performance. The aerogel exhibits low detection limit (50 ppb) toward NO ₂ at room temperature, while after the two-step sulfurizationmore »« less

Platinum Nanoparticle Loading of Boron Nitride Aerogel and Its Use as a Novel Material for Low-Power Catalytic Gas Sensing

Journal Article Harley-Trochimczyk, Anna ; Pham, Thang ; Chang, Jiyoung ; ... - Advanced Functional Materials

We report that a high-surface-area, highly crystalline boron nitride aerogel synthesized with nonhazardous reactants has been loaded with crystalline platinum nanoparticles to form a novel nanomaterial that exhibits many advantages for use in a catalytic gas sensing application. The platinum nanoparticle-loaded boron nitride aerogel integrated onto a microheater platform allows for calorimetric propane detection. The boron nitride aerogel exhibits thermal stability up to 900 °C and supports disperse platinum nanoparticles, with no sintering observed after 24 h of high-temperature testing. The high thermal conductivity and low density of the boron nitride aerogel result in an order of magnitude faster responsemore »« less

Effects of ambient humidity and temperature on the NO ₂ sensing characteristics of WS ₂/graphene aerogel

Journal Article Yan, Wenjun ; Worsley, Marcus A. ; Pham, Thang ; ... - Applied Surface Science

The effects of ambient humidity and temperature on the NO ₂ sensing characteristics of WS ₂/graphene aerogel (WS ₂/GA) composite are investigated. In order to probe the gas sensing performances of WS ₂/GA, the sensor is fabricated by integrating WS ₂/GA with a microfabricated two-electrode device. The WS ₂/GA is characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and nitrogen porosimetry. This hybrid nanomaterial is found to improve the selectivity to NO ₂, compared to control graphene and WS ₂ aerogels. The NO ₂ sensing performance of the WSmore »« less

Functionalized silica aerogels for gas-phase purification, sensing, and catalysis: A review

Journal Article Amonette, James E. ; Matyáš, Josef - Microporous and Mesoporous Materials

Silica aerogels have a rich history and offer an unusual assembly of gas- and solid-phase properties that has lent them to many diverse applications. This review starts with a brief discussion of the fundamental issues driving the movement of gases in silica aerogels and then proceeds to provide an overview of the work that has been done with respect to the purification of gases, sensing of individual gases, and uses of silica aerogels as catalysts for gas-phase reactions. We present salient features of the research behind these different applications, and, where appropriate, critical aspects that affect the practical use ofmore »« less

Self-assembly and metal-directed assembly of organic semiconductor aerogels and conductive carbon nanofiber aerogels with controllable nanoscale morphologies

Journal Article Turner, Sally ; Shevitski, Brian ; Long, Hu ; ... - Carbon

A versatile and highly tunable synthesis for nanofiber aerogels based on the n-type organic semiconductor perylene tetracarboxylic diimide (PTCDI) is presented. PTCDI nanofiber aerogels are demonstrated to incorporate the organic semiconductor into a high surface area and porous morphology, and can also be graphitized to synthesize carbon nanofiber (CNF) aerogels by thermal annealing. Using this approach, CNF aerogels with variable density and crystallinity are synthesized. Furthermore, by incorporating metal salts into the synthesis, metal-directed assembly yields a variety of nanoscale morphologies. The selection of post-synthesis thermal treatment can result in metal-directed assembly of PTCDI aerogels, low crystallinity graphitic aerogels decoratedmore »« less
