We report here an high specific surface area activated carbon loaded with hemin (H-PAC) synthesized by one-step in situ pyrolysis of paper. As the carrier of hemin, paper-derived activated carbon (PAC) showed high specific surface area (3157 m2 g-1) after optimization. The surface concentration of hemin in the material was effectively increased. In particular, PAC had a unique interconnected porous structure, which can be used as a continuous conductive framework and provide more active sites. Hemin maintained peroxidase-like activity and showed superior synergistic effect with PAC via pyrolysis, displaying rapid redox characteristics. Under optimized conditions, the composite exhibits high electro–catalytic activities for H2O2 reduction with a low detection limit of 0.087 μM, and high selectivity.

“…GFs were initially synthesized involving glucose and Na 2 CO 3 . 28 The interconnected framework of GFs is illustrated through scanning electron microscopy (SEM) (Figure S1). Subsequently, the Ru species underwent an in situ transformation, resulting in Ru single atoms being confined within the GFs using a photoreduction method (Scheme 1).…”

“…25,27 In our earlier work, we obtained 3D graphene frameworks (GFs) through the fast pyrolysis of glucose and sodium carbonate (Na 2 CO 3 ). 28 GFs possess richly porous network structures and oxygen-containing functional groups in addition to exhibiting the existence of Na elements. From these perspectives, it appears to be a viable strategy to use GFs as an effective support to construct highly efficient single atoms through a one-step photoreduction process without the need for the NaOH treatment of graphene.…”

A rational design of high-efficiency single atoms represents a desirable goal for the construction of efficient electrochemical devices. Nevertheless, their activity is constricted by the exposure of single atoms to reactants. Herein, novel ruthenium (Ru) single atom anchored on graphene frameworks (GFs) that feature interconnected porous structures (defined as Ru SA/GFs) is synthesized through a one-step photoreduction strategy. Ru SA/GFs possess additional structural merits that favor promoting reactant transport and maximizing the efficacy of single atoms, which manifest notable amplified electrocatalytic-reduction activity toward hydrogen peroxide (H2O2) than that of Ru nanoparticles/GFs, indicating the remarkable biomimetic nanozyme-like activity of Ru SA/GFs toward H2O2. Density functional theory (DFT) calculations reveal that Ru SA/GFs with atomically dispersed Ru significantly facilitate the electrochemical reduction efficiency toward H2O2. In addition, a sensitive Ru SA/GFs-based electrochemical sensing platform for the detection of H2O2 with a low detection limit of 0.063 μM is developed and demonstrated. This work not only exploits an innovative approach to synthesize single-atom Ru anchored on GFs for the construction of an efficient biomimetic H2O2 electrochemical sensor but also contributes to the broader utilization of Ru single atom in the advancement of diverse high-performance electrochemical devices.
