To develop a highly active high temperature water-gas shift (HTS) catalyst for hydrogen production from waste derived synthesis gas, MFe2O4 spinel catalysts (M = Ni, Co, and Zn) have been applied for the target reaction. Despite the high CO concentration in the simulated waste derived synthesis gas, NiFe2O4 catalyst (inverse spinel ferrite) exhibited the highest CO conversion (90.1% at 400 °C) at a very high gas hourly space velocity (GHSV) of 40,057 h-1. The outstanding catalytic activity is mainly due to easier reducibility of Fe2O3 to Fe3O4 and high BET surface area.
