Selective Reduction of Oxygen Functional Groups to Improve the Response Characteristics of Graphene Oxide-Based Formaldehyde Sensor Device: A First Principle Study

This paper presents a density functional theory-based first principle study to investigate the atomic-scale interactions of formaldehyde (H2CO) molecules with different oxygen containing functional groups of graphene oxide to identify which particular functional group possesses better adsorption capability toward H2CO molecule. The detailed study on formaldehyde adsorption has been conducted in te...
