【 摘 要 】

In this report, Platinum manganese nanoparticles (PtMn NPs) were attached onto Layered Double Hydroxide (LDH) via a facile in-situ growth strategy. Based on the prepared nanoparticles, a novel colorimetric sensor for fast and sensitive determination of H2O2 was established. The established colorimetric sensing platform exhibited perfect peroxidase-like activities confirmed by oxidating 4, 4'-Bi-2, 6-xylidine (TMB) with H2O2. The sensing platform was pH and temperature-dependent.
