• application. Consequently, researchers are working on discovering and developing catalysts for OER and ORR that are metal-free or based on non-noble metals, stable and earth-abundant [6][7][8][9][10]. Among the transition-metal-based OER and ORR catalysts, Ni-containing catalysts are promising candidates [7

These results show that this new washing procedure is efficient to removed unalloyed non noble metals. Its impact on the structure

• . The use of Pt3M/N-CNT catalysts results in the reduction in the quantity of H2O2 produced during the ORR compared to the commercial Pt3Co/CB catalyst. After ex situ validation of the catalyst, the treatment with EDTA solution to remove unalloyed non noble metals (Co or Ni) was employed. The

However, these noble metals are associated with high cost and low availability, so non-noble metals, such as Ni [18][22][23][24], Fe [25][26][27][28], and Co [29][30] are most often used. Among the non-noble metals, Ni
