Herein, we demonstrate a facile, but rational and effective solvothermal approach to the synthesis of hierarchical NiO mesoporous nanospheres (NiO-MNS) as an effective non-enzymatic sensor towards the H₂O₂ detection. Owing to the intercalation and stabilization effect of polyethylene glycol for the Ni(OH)₂ intermediate, the NiO mesoporous nanosphere (NiO-MNS) product is consistent with the low-dimensional nanostructured NiO blocks with large surface area and plentiful mesopores after the calcination treatment. The obtained NiO-MNS sensor presents superior electrochemical performaRSC advances13401-13407https://www.ebi.ac.uk/biostudies/studies/S-EPMC9079751biostudies-literatureMesoporous NiO nanosphere: a sensitive strain sensor for determination of hydrogen peroxide.PMC9079751Liu HDou MZhang ZZhang XWang FLi QGao WfalseMesoporous NiO nanosphere: a sensitive strain sensor for determination of hydrogen peroxide.Exploring the sensitive and reliable methods for the determination of hydrogen peroxide (H₂O₂) is a crucial issue for the health and environmental challenges.
