2D Materials: 2D Materials Decorated with Ultrathin and Porous Graphene Oxide for High Stability and Selective Surface Activity (Adv. Mater. 36/2020)

In article number 2002723, Jihan Kim, Sang Ouk Kim, Il‐Doo Kim, and co‐workers develop “Janus‐like” 2D porous heterostructures for realizing ultrastable surface reactivity of 2D materials, as proven by a chemical‐sensing case study and multiscale simulations. The few‐layered holey graphene oxide passivation layer effectively shields black phosphorus and MXene from oxidative degradation, while allowing the selective diffusion of NO 2 molecules toward the underlying 2D sensing layer.
