Two-dimensional (2D) mesoporous transition metal oxides are highly desired in various applications, but their fast and low-cost synthesis remains a great challenge. Herein, a Maillard reaction inspired microexplosion approach is applied to rapidly synthesize ultrathin 2D mesoporous tin oxide (mSnO2). During the microexplosion between granular ammonia nitrate with melanoidin at high temperature, the organic species can be carbonized and expanded rapidly due to the instantaneous release of gases, thus producing ultrathin carbonaceous templates with rich functional groups to effectively anchor SnO2 nanoparticles on the surface. The subsequent removal of carbonaceous templates via calcination in air results in the formation of 2D mSnO2 due to the confinement effect of the templates. Pd nanoparticles are controllably deposited on the surface of 2D mSnO2 via in situ reduction, forming ultrathin 2D Pd/mSnO2 nanocomposites with thicknesses of 6–8 nm. Owing to the unique 2D mesoporous structure with rich oxygen defects and highly exposed metal–metal oxide interfaces, 2D Pd/mSnO2 exhibits excellent sensing performance toward acetone with high sensitivity, a short response time, and good selectivity under low working temperature (100 °C). This fast and convenient microexplosion synthesis strategy opens up the possibility of constructing 2D porous functional materials for various applications including high-performance gas sensors.

Foodborne pathogens are a crucial diagnostic target for the food, beverage, and healthcare sectors due to their ubiquity and the potential damage they may do to the public's well‐being, food safety, and the economy. Over the past few decades, there has been an increased focus on developing highly precise and trusted biosensors in an effort to eliminate the discrepancy between reporting demands and currently used traditional detection approaches. Metal oxide semiconductor (MOS)‐based gas sensors have rapidly advanced in recent years, becoming a dominating technology for developing devices in food‐quality management, biomedical research, and diagnostics. This review systematically explores recent advancements in gas sensing technologies utilizing metal oxide‐based sensors for the detection of foodborne pathogens through the analysis of volatile organic compounds (VOCs). The comprehensive discussion encompasses insights into various foodborne pathogens, their implications for human health, diverse metal oxide characteristics, strategies for enhancing their sensing capabilities, and the distinctive features of VOCs. Furthermore, a thorough examination of the utilization of different metal oxides in VOC sensing is provided, addressing both existing challenges and potential future developments. In summary, employing gas sensing techniques for foodborne pathogen detection holds substantial commercial promise compared to alternative bio‐sensing approaches.
