TL;DR: Gas sensors using Tb-doped SnO2 yolk-shell spheres can be used for reliable acetone detection, regardless of the variations in humidity, and can provide a new road to achieve highly sensitive, selective, and humidity-independent sensing of acetone.

TL;DR: A photoactive amine functionalized Ti metal-organic framework (MOF) layer is uniformly coated on vertically ordered TiO2 nanorods (NRs) via a facile hydrothermal reaction, and the performance of the heterojunction photoanode in photoelectrochemical (PEC) water splitting is studied in this paper.

TL;DR: The mechanism for the humidity-immune gas-sensing characteristics was investigated by X-ray photoelectron and diffuse reflectance infrared Fourier transform spectroscopies together with the phenomenological gas-Sensing results and discussed in relation with Pr3+/Pr4+ redox pairs, regenerative oxygen adsorption, and scavenging of hydroxyl groups.

TL;DR: In this article, a galvanic replacement of Zn in ZnO hollow spheres by Cr 2 O 3 and ZnCr 2 O 4 particles was used to achieve high selectivity and response to xylene.

TL;DR: A Highly ordered CdS nanoflake array was fabricated by CVD, and its gas sensing characteristics were investigated in this article, where the sensor exhibited high response (resistance ratio) of 89% to 5 part per million (ppm) nitrogen dioxide (NO 2 ) under green LED illumination.
