Title: Catalytic hydrogen sensing using microheated platinum nanoparticle-loaded graphene aerogel

Abstract

We present that low power catalytic hydrogen sensors are fabricated by functionalizing low power polysilicon microheaters with platinum nanoparticle catalyst loaded in a high surface area graphene aerogel support. Fabrication and characterization of the polysilicon microheaters are described. The platinum nanoparticle-loaded graphene aerogel is characterized by transmission electron microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy. Finally, the catalytic hydrogen sensors consume as little as 2.2 mW of power, have sensitivity of 1.6%/10,000 ppm hydrogen, a t90 response and recovery time of 0.97 s and 0.72 s, respectively, a lower detection limit of approximately 65 ppm, and negligible cross sensitivity to methane, n-pentane, and diethylether.

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

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 response and recovery times (more »« less

Boron Doping and Defect Engineering of Graphene Aerogels for Ultrasensitive NO ₂ Detection

Journal Article Turner, Sally ; Yan, Wenjun ; Long, Hu ; ... - Journal of Physical Chemistry. C

In this study, boron-doped and defect-engineered graphene aerogels are prepared using triphenyl boron as a boron precursor and subsequent heat treatments. The boron chemistry and concentration in the graphene lattice are found to be highly dependent on the temperature used to activate boron. At 1500 °C, boron is incorporated at 3.2 atom % through a combination of B–C, B–N, and B–O bonds. At 1750 °C, the boron concentration decreases to 0.7 atom % and is predominantly incorporated through B–N bonding. Higher temperatures result in complete expulsion of boron from the lattice, leaving behind defects that are found to be beneficialmore »« less

A MoS 2 /graphene hybrid aerogel synthesized with two-dimensional MoS 2 sheets coating a high surface area graphene aerogel scaffold is characterized and used for ultrasensitive NO 2 detection. The combination of graphene and MoS 2 leads to improved sensing properties with the graphene scaffold providing high specific surface area and high electrical and thermal conductivity and the single to few-layer MoS 2 sheets providing high sensitivity and selectivity to NO 2 . The hybrid aerogel is integrated onto a low-power microheater platform to probe the gas sensing performance. At room temperature, the sensor exhibits an ultralow detection limit ofmore »« less

3D MoS₂ Aerogel for Ultrasensitive NO₂ Detection and Its Tunable Sensing Behavior

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

A high-performance NO₂ sensor based on the 3D MoS₂ aerogel is introduced. Compared to single- or few-layer MoS2, 3D assemblies of 2D MoS₂ provide more surface area per footprint with a simple and scalable synthesis. Integration of the 3D MoS₂ aerogel on a low-power microheater platform is demonstrated, and the sensing behavior of the 3D MoS₂ aerogel is investigated. A two-step sulfurization treatment is developed to obtain a high-quality MoS₂ aerogel with strong sensing performance. The aerogel exhibits low detection limit (50 ppb) toward NO₂ at room temperature, while after the two-step sulfurization treatment, it also exhibits fast response andmore »« less

Effects of ambient humidity and temperature on the NO₂ sensing characteristics of WS₂/graphene aerogel

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

The effects of ambient humidity and temperature on the NO₂ sensing characteristics of WS₂/graphene aerogel (WS₂/GA) composite are investigated. In order to probe the gas sensing performances of WS₂/GA, the sensor is fabricated by integrating WS₂/GA with a microfabricated two-electrode device. The WS₂/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 NO₂, compared to control graphene and WS₂ aerogels. The NO₂ sensing performance of the WS₂/GA-based sensors is investigated under different relative humidities (0–60%), andmore »« less
