The biochar peroxidase-like activity also depends on the particle size, as documented in Fig. 2b for maize cob (MC) biochar. As expected, smaller biochar particles exhibit higher activity. A similar situation was also observed in the case of nanomaterials mimicking peroxidases; this phenomenon may be due to the smaller particles having a greater surfaceto-volume ratio to interact with their substrates. This observation suggests that selective fabrication of peroxidase-like materials with diferent size and shape is very important to modulate their catalytic activities (Jv et al. 2010; Peng et al. 2015). |
