摘要：Electrochemical treatment was employed to improve the electric conductivity gamma-Al2O3/Al. Optimal conditions were found to be 0.5 M KCI solution along with potential of 4 V for 7.5 min. The modified gamma-Al2O3/Al support showed higher catalytic activity at low temperature because of its bigger specific surface area and more acid amount than gamma-Al2O3/Al. Moreover, Ni was easily loaded on the modified Cu/gamma-Al2O3/Al catalyst through electrolysis because of the high electric conductivity. The novel Ni/Cu/gamma-Al2O3/Al catalyst also exhibited excellent stability for 40 h at 623 K with 100% conversion and 70% H-2 yield in steam reforming of dimethyl ether.
