Controllable hydrogen production via the catalytic decomposition of hydrous hydrazine (N2H4·H2O) holds significant promise for mobile and portable applications. However, current catalysts suffer from unsatisfactory reaction activity and hydrogen (H2) selectivity. Based on the unique redox properties of CeO2, this article aims to enhance the thermal catalytic performance for the decomposition of N2H4·H2O by improving metal-support interactions between the TiCeO2 and NiPt active components. Meanwhile, the sea urchin-like TiCeO2 support, which is more conducive to the dispersion of the NiPt nanoparticles and provides more reactive sites for the reaction, was used to immobilize Ni-Pt into the NixPt1‒x/TiCeO2 sample using the impregnation-reduction method. By modulating Ce doping and the Ni-Pt molar ratio, samples with different Ni-Pt compositions were synthesized. The optimal Ni0.5Pt0.5/TiCeO2 (nNi: nPt = 1) shows the highest catalytic performance compared with the other samples, with a TOF (turnover frequency) of 212.58 min−1 and 100% hydrogen selectivity at 323 K. Furthermore, the hydrogen selectivity remains 100% after six cycles. This remarkable activity and stability provide valuable insights and encouragement for accelerating the practical application of N2H4·H2O as a viable hydrogen carrier
