Ever since Nobel laureates Novoselov and Geim have discovered the two dimensional graphene in 2004 , it has been introduced in various electrochemical devices, such as sensors , lithium-ion batteries , dye-sensitized solar Methimazole ,  and , and capacitors , owing to the remarkable electrical, optical, thermal, and mechanical properties of graphene as well as its extraordinarily high surface area (∼2,630 m2 g−1) . Doping graphene with foreign heteroatoms, e.g., nitrogen, boron, sulfur and phosphorus, is one of the effective approaches to tailor its electronic properties and electrochemical activities . Chemical doping of boron is effective because boron can create defects in the nearby sites and induce the uneven charge distribution, which can facilitate the charge transfer between neighboring carbon atoms and enhance the electrochemical performance . Adjizian et al. illustrated boron-doped multi-wall carbon nanotubes as a potential candidate for gas detection . Kim et al. prepared substitutionally boron-doped single-layer graphene by using the mechanical exfoliation of boron-doped graphite . Recently, Yang et al. synthesized nitrogen and boron co-doped graphene as the catalyst for H2O2 detection by using a microwave-assisted synthesis method to obtain enhanced H2O2 electrocatalytic activity . However, embryo is still lacking a facile synthesis of B-doped graphene at atmospheric-pressure and a systematic study on the electrochemical detection of H2O2 using B-doped graphene.
