Fig. 3: Investigation of the role of the hydrophobic nature of the pore wall of MPRs in H2O2 generation.

A Scheme of hydrophilic treatment of XAD-1180N MPRs by grafting dextran structures onto their phenyl rings. B The recorded rate of H2O2 generation for XAD-1180N MPRs at different degrees of hydrophilic treatment and their contact angles. C Scheme of hydrophobic modification of sengarose, a typical porous and hydrophilic agarose gel, by grafting hydrophobic butyl groups onto its hydroxyl groups. D The generation rate of H2O2 for sengarose at different levels of hydrophobic treatment and their contact angles. Data in (B, D) are presented as mean ± standard deviation (n = 3 independent experiments).
