This study aims to investigate the performance of novel Cu1−xMnxAl2O4 catalysts for hydrogen production via methanol steam reforming.
Synthesis of Cu1−xMnxAl2O4 catalysts.
Characterization of catalyst structure using XRD, SEM, and EDS.
Evaluation of hydrogen production performance in a fixed-bed reactor.
Testing at LHSV of 20 h−1, water-to-methanol ratio of 3:1, and temperatures from 275 °C to 350 °C.
Cu0.7Mn0.3Al2O4 catalyst achieved methanol conversion of 68.336% at 325 °C.
Hydrogen production rate reached 5.611 mmol/min/gcat.
CO selectivity maintained below 1%.
A-site Mn substitution improved catalytic performance but excessive substitution led to impurity phase formation.
