【摘要】 用TEM研究了Ni-RE-Ba-Ti-O催化材料,结果表明其粒径大小均在纳米级。用XRD测试了添加稀土和不同稀土的催化剂,发现它们的晶型没有发生改变。考察了溶胶-凝胶法制备催化剂的XRD谱图,此法添加稀土后对谱图影响较大,比浸渍法制备的催化剂更膨松,具有更高的比表面和孔结构。更多还原

【Abstract】 Ni-RE-Ba-Ti-O catalysts was characterized by TEM. Their particle sizes are all nanometer grade. The catalyst was measured with different rare earths and different content by XRD. This does not affect structure of matrix. XRD patterns of catalytic materials was investigated by sol-gel. The method with rare earth affects the patterns greatly.更多还原
