Improving steam-reforming performance by nanopowdering CuCrO2

Hydrothermal synthesis of high surface area CuCrO2 for H2 production by methanol steam reforming

“…6. The comparison showed that the hydrogen production efficiency of the hydrothermallysynthesized CuCrO 2 nanopowder was much higher than those of the CuCrO 2 nanopowder catalysts prepared by GNP method, 6 commercial Cu/Al/Zn catalyst, 23 and CuCrO 2 bulk power catalyst. 29 Commonly, a H 2 -activated catalyst is dangerous when exposed to air due to its high activity and potential for ignition and explosion, but CuCrO 2 nanopowder is very stable in air.…”

“…It also lacks a carbon-carbon bond, is low in sulfur compounds (<5 ppm), and yields a smaller quantity of carbonaceous products. 5 Generally, hydrogen is produced from methanol by reactions such as decomposition, 6 methanol steam reforming (MSR), and partial oxidation, which are described in the following chemical reactions. The decomposition reaction produces a high amount of CO, which can damage the electrode and decrease the power density of fuel cells, so it is not an ideal process for fuel cells.…”

Preparation of CuCrO2 nanowires by electrospinning

“…After 30 min annealing, the particles were disappeared and wire became slightly coarse and looked rough. Even though CuCrO 2 phase were not obtained, that's Cu/Cr 2 O 3 nanowire maybe suite to apply as a catalyst for steam reforming of method [7,8]. …”

“…CuCrO 2 is also one of the most promising candidates for p-type transparent optoelectronic devices. Currently, researchers have been exploring new properties on delafossite oxides such as photocatalyst for heavy metal reduction [4,5], hydrogen evolution [5,6], NO 2 removal [6], catalysts for steam reforming process [7,8], exhaust gas purification, room temperature ozone sensors [9], and thermoelectric devices [10].…”

Preparation of CuCrO2 Hollow Nanotubes from an Electrospun Al2O3 Template

“…The delafossite structure of copper-based catalysts also has great importance in catalytic steam reforming of methanol to hydrogen production and heterogeneous catalysis for chlorine production due to their high thermal stability, fine porous structure, high surface area, high selectivity, and excellent activity at low temperature. Besides, copper delafossite materials are more stable than Ru, Pd, Au, and Pt catalyst at the steam reforming process [14,15,16]. Cu-based delafossites have been reported including CuAlO 2 [17], CuFeO 2 [18], CuGaO 2 [19], CuInO 2 [20], CuScO 2 [21], CuCrO 2 [22], and Mg-doped CuCrO 2 [23,24].…”
