In this communication, we describe the development of nickel phosphide nanosheets array on titanium mesh (Ni2P NA/TM) as a non-precious metal catalyst electrode toward hydrogen peroxide (H2O2) reduction in neutral solution. As an non-enzymatic H2O2 sensor, the Ni2P NA/TM presents superior analytical performances with rapid response time of less than 5 s, a wide linear range of 0.001-20 mM, a low detection limit of 0.2 mM (S/N = 3), and a high sensitivity of 690.7 mA mM(-1)cm(-2), as well as high selectivity and long-term stability.
