Cu2O/CuO@rGO heterostructure derived from metal–organic-frameworks as an advanced electrocatalyst for non-enzymatic electrochemical H2O2sensor

A hybrid heterostructure comprising well-dispersed Cu₂O/CuO particles and reduced graphene oxide (rGO) is synthesized by calcinating a mixture of MOFs-118 and GO in nitrogen atmosphere to improve the sensitivity and selectivity of H₂O₂sensors.
