| description | The Co<sub>3</sub>O<sub>4</sub> is a typical p-type metal oxide semiconductor (MOS) that attracted great attention for hydrogen detection. In this work, porous, urchin-like Co<sub>3</sub>O<sub>4</sub> was synthesized using a hydrothermal method with the assistance of glucose and a subsequent calcination process. Urchin-like Co<sub>3</sub>O<sub>4</sub> has a large specific surface area of 81.4 m<sup>2</sup>/g. The response value of urchin-like Co<sub>3</sub>O<sub>4</sub> to 200 ppm hydrogen at 200 °C is 36.5 (R<sub>g</sub>/R<sub>a</sub>), while the low-detection limit is as low as 100 ppb. The obtained Co<sub>3</sub>O<sub>4</sub> also exhibited good reproducibility, long-term stability, and selectivity towards various gases (e.g., ammonia, hydrogen, carbon monoxide, and methane). Porous, urchin-like Co<sub>3</sub>O<sub>4</sub> is expected to become a potential candidate for low-concentration hydrogen-sensing materials with the above advantages. |
