A Nickel‐Based Pectin Metal‐Organic Framework as a Hydrogen Oxidation Reaction Catalyst for Proton‐Exchange‐Membrane Fuel Cells

Abstract

Environmentally friendly non‐PGM (platinum group metal) anode catalyst made of nickel pectate, the biological raw material, was developed and tested in proton‐exchange‐membrane fuel cell (PEMFC). 5.2 mA cm‐2 and 1.5 mW cm‐2, the maximum current density and the maximum power density of the developed catalyst, respectively, correspond to sufficiently high values of these characteristics for PEMFC with an anode without a PGM catalyst and a cathode with a platinum one.

Carbonized Nickel Complex of Sodium Pectate as Catalyst for Proton-Exchange Membrane Fuel Cells

“…Research has shown that sodium pectate with a 25% substitution of sodium ions for nickel ones can be used as ORR [ 8 ] and HOR [ 9 ] catalysts in PEMFCs as an active material in non-platinum catalytic systems. Recently, varying the concentration of Ni(II) ions in nickel complexes of sodium pectate [ 10 ] allowed researchers to find the optimal concentration of the transition metal to improve the characteristics of the studied PEMFCs.…”

Photoresponsive Metal-Organic Frameworks as Adjustable Scaffolds in Reticular Chemistry

“…Several scientists have been attracted by this important part of reticular chemistry [9][10][11][12], probably due to the fact that the researcher's inventiveness is the only limitation in this research field. Thus, different research groups have greatly contributed to the exponential growth of this area, using these materials in a diverse range of applications, including catalysis [13][14][15][16][17][18][19], water harvesting [20][21][22][23], biomedicine [24][25][26] and sensing [27][28][29][30].…”
