<P><B>Abstract</B></P> <P>The simple and eco-friendly fabrication of non-noble metal catalyst is of great importance for sustainable energy production from alcohol. Herein, we report the new synthetic route for the preparation of nickel phosphate nanostructure through simple co-precipitation method. We studied the effect of annealing temperature ranging from 500°C to 1100°C on the electrocatalyst for ethanol electro-oxidation. In addition, we demonstrate that the resulting nickel phosphate materials can serve as efficient transition metal electrocatalyst for the ethanol oxidation under alkaline condition. In particular, the nickel phosphate annealed at 900°C (NP-900) affords higher current density of 1.2mAcm<SUP>−2</SUP> at the low potential of 0.7mV, demonstrating great catalytic stability as well as good cyclability for 1000cycles giving about 92% faradaic yield towards the ethanol.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Simple and eco-friend no-noble metal catalysts were synthesized. </LI> <LI> Electrochemical performances of the resulting nickel phosphate were investigated. </LI> <LI> Effect of annealing temperature of nickel phosphate on electrocatalyst was studied. </LI> <LI> Catalytic stability and cyclability of nickel phosphate were studied. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
