Abstract

Increasing greenhouse gas (GHG) emissions, such as methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2), from agricultural practices and land use have increased concerns about global warming. Accurate quantification of the GHG using gas sensors is essential for effective management and sustainable agricultural practices. The objective of this study was to make an analytical comparison of the performance of various sensing materials for CH4, N2O, and CO2-based sensors in terms of sensitivity, response ratio, response time, and recovery time to establish an efficiency detection level of the GHG emissions. A literature review of 95 different studies showed that palladium-tin dioxide nanoparticles (Pd-SnO2), indium oxide (In2O3) nanowires, and gold-lanthanum oxide-doped tin dioxide nanofibers (Au-La2O3/SnO2) had better performance compared to other sensing materials in CH4, N2O and CO2-based sensors, respectively. The findings from reviewed studies revealed that nanoporous structures, nanowires and nanofibers had faster response and recovery compared to conventional materials due to their big specific surface area (SSA). The designed ternary hybrid structure of sensing materials was more effective for CO2 gas detection than the double hybrid structure, unlike CH4 and N2O-based sensors. However, constructive suggestions for researchers were discussed in the conclusion based on the current research status and challenges to improve the performance of GHG sensors.
