“…These methods include spectrophotometry [16], gas chromatography (GC) [17], high-performance liquid chromatography [18], ion chromatography [19] and polarography [20]. Since these methods required expensive and bulky instrumentation with high power demand and well-trained operators, clearly, these procedures is unable to provide formaldehyde exposure information on a real-time basis.…”

Many methods based on spectrophotometric, fluorometric, piezoresistive, amperometric or conductive measurements have been proposed for detecting the concentration of formaldehyde in air. However, conventional formaldehyde measurement systems are bulky and expensive and require the services of highly-trained operators. Accordingly, the emergence of sophisticated technologies in recent years has prompted the development of many microscale gaseous formaldehyde detection systems. Besides their compact size, such devices have many other advantages over their macroscale counterparts, including a real-time response, a more straightforward operation, lower power consumption, and the potential for low-cost batch production. This paper commences by providing a high level overview of the formaldehyde gas sensing field and then describes some of the more significant real-time sensors presented in the literature over the past 10 years or so.

“…Therefore, the detection of formaldehyde gas is significantly important. Until now, numerous technologies have been employed, such as spectrophotometry [2], gas chromatography (GC) [3], high-performance liquid chromatography [4], ion chromatography [5], polarography [6], and integrated sensor [7]. Among the above-mentioned techniques, the gas sensors have been widely reported by many research groups due to the advantages of high sensitivity, fast response, high stability, small size, and cost-effective features.…”

Ultrafine Pd nanocrystals were grown on the cobalt phosphide (Co 2 P) decorated Vulcan XC-72 carbon (C/Co 2 P), which is realized by first implementing the corresponding metal precursor and then the further chemical reduction process. The as-synthesized C/Co 2 P/Pd composite was further constructed to form a gas permeable electrode. This electrode can be applied for formaldehyde (HCHO) detection. The results demonstrate that the Co 2 P nanocrystal can significantly improve the sensing performance of the C/Co 2 P/Pd electrode for catalytic oxidation of HCHO, which is considered to be attributed to the effective electron transfer from Co 2 P to Pd in the C/Co 2 P/Pd composites. Furthermore, the assembled C/Co 2 P/Pd sensor exhibits high sensitivity of 617 nA/ppm and good selectivity toward various interfering gases such as NO 2 , NO, SO 2 , CO 2 , and CO. It also shows the excellent linear response that the correlation coefficient is 0.994 in the concentration range of 1-10 ppm. Therefore, the proposed cost-effective C/Co 2 P/Pd nanocomposite, which owns advantages such as high activity and good stability, has the potential to be applied as an effective electrocatalyst for amperometric HCHO detection.

“…These methods include chromatography [6][7][8][9][10], spectroscopy [11][12][13][14], and electrochemistry [15][16][17][18][19][20]. Although these methods enable the measurement of formaldehyde at the ppb level, their application for personal household use is problematic, as they require expensive equipment, complex manipulation, and a long measurement time.…”
