Alcohol has a potential health risk to human health, so it is important to realise the rapid detection of alcohols. Based on this, the nano Na 2 Mg(CO 3 ) 2 was prepared by a simple hydrothermal method to establish a cataluminescence (CTL) gas sensor for alcohols. The Na 2 Mg(CO 3 ) 2 with highly purified quality was characterised by scanning electron microscope, energy dispersive spectroscopy and the powder X‐ray diffraction. The results show that the nano Na 2 Mg(CO 3 ) 2 is a peony‐like substance with a large surface area, which will be beneficial to produce ultra‐weak chemiluminescence reaction between the detector and the material. The peony‐like Na 2 Mg(CO 3 ) 2 has good CTL response to alcohols (methanol, ethanol, n‐propanol and n‐butanol), showing high selectivity. The response time of Na 2 Mg(CO 3 ) 2 for four alcohols is between 1 and 2 s, which indicate that the material has the advantage of rapid response. The limit of detection of four alcohols defined as 3 N/S is about 7.91, 4.75, 6.69 and 8.10 mg/l, respectively. The optimum reaction conditions of the gas sensor based on nano Na 2 Mg(CO 3 ) 2 are mild and this nanomaterial can be used for alcohol detection.
