Boron decorated graphene acts as an ultrasensitive sensor

What is it about?

we used first-principle calculations to study the electrochemical properties of pure graphene (PG) in addition to various coverages of BG upon adsorption of CO as a lethal gas. We observe stronger adsorption as well as higher charge transfer in terms of increasing the B-coverage (Θ) from CO to graphene. Moreover, adsorption energies are scaled substantially by the rate of coverage attributed to the role of co-adsorption.

Why is it important?

Our results confirm experimental data on the enhanced gas sensitivity of boron-doped graphene and show that B-decorated manipulation of the graphene layer is potentially very favorable for designing new sensors for toxic gas detection.
