fuel cell; hydrogen generation; Ni-B alloy; catalyst 1 Introduction With the rapid development of proton exchange membrane fuel cells (PEMFC), which adopts pure hydrogen as the best fuel, hydrogen... at 350 ℃ and 400 ℃, which have high surface metal Ni, can still show good hydrogen generation performances. However, the 500 ℃ treated catalyst has much smaller BET surface areas than other Ni-B......
, which implies that NOx is almost entirely converted to N2 over Cu-SAPO-34/cordierite catalyst. The conversion rate of NOx to N2 by NH3 over catalyst could almost be up to 100% in the temperature range... with H2O. Key words: in situ synthesis; Cu-SAPO-34/cordierite; NOx; selective catalyst reduction; NH3; diesel vehicle exhaust 1 Introduction The number of diesel vehicles is gradually increased due......
Effect of Ceria on Structure and Thermostability of Copper-Iron-Oxide Catalyst WANG Ren1,LU Guan-zhong1,WANG Jun-song1,WANG Xing-yi1 (1.Research Institute of Industrial Catalysis, East China... techniques. The studies indicate that there are Fe2CuO4, CuO and α-Fe2O3 phases in Cu-Fe-O with the granula of less than 13 nm. With the catalyst pretreatment temperature rising, the crystallite......
Ce-Zr-Tb Oxide Solid Solution as Key Material for Three-Way Catalyst Hu Yucai1 (1.School of Chemistry and Material Sciences, Yantai Normal University, Yantai 264025, China) Abstract:Ce-Zr-Tb oxide..., The palladium-only three-way catalyst(TWC) containing CZT was prepared by slurry coating and its catalytic activity was evaluated under the condition of simulated exhaust. The results show that CZT has cubic......
