摘要

•The CuO-CeO2 offered various catalytic active sites.•MXene accelerated the electron transfer.•The electrocatalysis rate of H2O2 was deduced to be 0.61 × 103 M−1 s−1.•The sensor based on CuO-CeO2/MXene exhibited a broad linear range with good stability for H2O2.•The preferential dissociation of H2O2 to hydroxyl radical was deduced on CeO2(111).
