“…To date, significant amount of research studies have been reported on the sensing of CO gas (Table S1, ESI †). First, very high sensor responses, in the range of 29-480, was attained by means of using various material systems, including Au and SnO 2 nanocrystals on CNTs, 18 Co 3 O 4 nanowires, 19 In 2 O 3 raspberry hollow spheres, 20 Au-doped SnO 2 -In 2 O 3 nanocomposites, 21 Pt/SnO 2 , 22,23 and Sm 2 O 3 -doped Pt/SnO 2 . 23 However, the concentration of CO gas was set to 100-1000 ppm.…”

Accordingly, there are rare reports on the preparation of a highly sensitive CO sensor operating at low concentrations below 10 ppm.…”

We report the fabrication of Pt@SnO2 nanoparticles using a sol–gel method. These nanoparticles are used as a sensing material. The structural and morphological characterization of the prepared Pt@SnO2 nanoparticles was performed using ultraviolet–visible spectroscopy, X‐ray diffraction, transmission electron microscopy, and energy‐dispersive X‐ray spectroscopy. The sensor responses of SnO2 and 1 wt% Pt/SnO2 to 1% hydrogen gas (H2) were 1.3 and 1.9, respectively. The sensor response of a Pt@SnO2 core–shell sensor increased to 5.1 at room temperature; it improved by 3.9 times compared to SnO2 and by 2.7 times compared to 1% Pt/SnO2 in sensing 1% H2. The response time for the prepared Pt@SnO2 sensor was also shortened by 2.0 and 1.4 times compared to SnO2 and 1 wt% Pt/SnO2, respectively. The sensor response increased rapidly from 1.4 to 5.1, with an increase in H2 concentration from 800 to 10,000 ppm (1%). We investigated the H2‐sensing mechanism of Pt@SnO2.

“…Otro de los metales nobles más utilizados como dopante, especialmente en sensores comerciales, es el platino. En forma similar al Pd, el platino (Pt) es también un catalizador superior y su papel en la promoción de la sensibilidad de SnO 2 continúa siendo estudiado hasta ahora [19][20][21][22][23][24][25]. El control de las configuraciones de partículas de Pt se ha considerado muy importante para el análisis de la detección de gases.…”
