文摘

The Ni-phytate electrode is prepared without the use of binder or conducting agent. More active sites and good charge transfer efficiency due to the film and bubble-like structure The Ni-phytate catalyst presents a low overpotential, small Tafel slope and good stability. The introduction of phytate units significantly improves the performance of the electrocatalyst. This method could be used to develop other catalysts based on transition metals.
