Co2V2O7,CoV2O6催化剂上丙烯选择性分别为48.12%,47.82%,35.24%.FTIR,XPS,H2-TPR和电导的研究结果表明,正,焦钒酸钴催化剂内各种价态钒之间易于进行氧化还原反应和形成氧缺位,钴含量的增加有利于丙烷转化的未充分还原的氧物种O2^-,O2^2-,O^-等增加,可以判断未充分还原的氧物种Oδ-(0〈δ〈2)是丙烷ODH...
Co3 V2O8和Co2 V2O7具有p-型半导体性质,CoV2O6表现n-型半导体性质.p-型半导体Go3 V2O8和Go2 V2o7的丙烷ODH催化性能优于n-型半导体CoV2O6,当丙烷的转化率在10%时,在Co3 V2O8,Co2 V2O7,CoV2O6催化剂上丙烯选择性分别为48.12%,47.82%,35.24%.FTIR,XPS,H2-TPR和电导的研究结果表明,正、焦钒酸钴...
用柠檬酸络合法制备了LaMn_(1-x)Co_xO_(3-λ)系列稀土复合氧化物。用XPS技术研究了它的表面、体内组态和结构变化及锰和钴含量对La 3d_(5/2)特征峰和Shske-up伴峰的影响。认为α-O是催化剂中的活性氧种。用氩离子剥离技术研究了LaMn_(1-x)Co_xO_(3-λ)体系,观察到锰在表面的偏析作用随x的减小而...
所以没做XPS然后我去打了XPS，碳校正以后得到的 Co 2p3/2的峰位置在781查阅过各种文献，文献上面也没...
向各位熟悉XPS的高手请教一下：Co3O4中的Co应该是以+3价和+4价态存在的，在XPS表征中应该有几对Co...
求助大神关于XPS，中怎么看出来哪个电子能是Cu.Co,Al,Si,O
一篇文章的题目为：Enhanced electrochemical performance of flower-like Co3O4 as an anode meterial ...
The interaction of small molecules (H 2 O, O 2 and CO 2 ) with polyphenylacetylene (PPA) thin films has been studied. The air-exposed PPA interacts with the atmosphere water vapour, leading to covalently bonded OH groups on the basis of X-ray photoelectron spectroscopy (XPS) core-level ...
