Au nanoparticle-decorated porous SnO2 hollow spheres: a new model for a chemical sensor

Utilization of both-side metal decoration in close-packed SnO2 nanodome arrays for ultrasensitive gas sensing

“…Excitingly, the both-side Au-decorated SnO 2 nanodome arrays exhibit the 18 times higher response than the bare SnO 2 nanodome. In our best knowledge, no work has demonstrated such a high response enhancement using metal decoration, which is much higher those of previously reported for high sensitivity sensors based on SnO 2 nanostructures with metal nanoparticles [30][31][32][33][34][35]. Another interesting result is that the response of inside Audecorated sample is higher than that of the outside Au-decorated sample despite of the similar distribution of Au nanoparticles.…”

Facile Synthetic Route for Thickness and Composition Tunable Hollow Metal Oxide Spheres from Silica‐Templated Coordination Polymers

“…Hollow micro-and nanostructures have received signifi cant attention due to their potential applications such as catalysts, [ 1 ] chemical sensors, [ 2 ] photonic devices, [ 3 ] energy storage, [ 4 ] chemical reactors, [ 5 ] and drug delivery. [ 6 ] Several methods, including template-free methods [ 7 ] and templating methods using either hard or soft templates, [ 8 ] have been developed to fabricate hollow structures.…”

Hydrothermal synthesis of sodium vanadium oxide nanorods for gas sensing application

“…To improve the gas sensing performance, various strategies have been investigated, including increasing the surface area [1], doping [2] and surface modifications with noble metal particles [3].…”
