Metallic catalysts (Cu/ZnO) and pure metals (Co, Ni, and Ag) without any impurities are directly prepared by a novel formic acid-assisted solid-state method without further reduction. During the decomposition of metal–formic acid precursors at 523K under argon, H 2 and CO are liberated and act in situ as reducing agents to obtain pure metals and metallic catalysts (C argon ). X-ray...
The water–gas shift (WGS) reaction over a series of cobalt-molybdenum carbide catalysts was studied at 453 K. The cobalt-molybdenum (Co x Mo 1−x ) oxides were prepared using a mixture of aqueous solutions of cobalt nitrate and ammonium heptamolybdate and carburized by a temperature-programmed reaction with a 20% CH 4 /H 2 mixture. The catalysts were characterized using...
