概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
The topic is to study zeolite catalysts for selective catalytic reduction of NOx with NH3. XPS can analyze the chemical states of metal species such as Cu and Fe in the mono-metal loaded and bi-metal loaded samples and help understand how it will further affect the catalytic performance as active sites.
実験 / Experimental
Cu-beta, Fe-beta and CuFe-beta (metal content around 1.5wt%) powder and pellet samples are prepared for XPS measurement(VersaProbe III).
結果と考察 / Results and Discussion
For powder samples, there is almost no
signal of metal elements because of the thickness of the sample.
For pellet samples, though there is very low signal for Fe (around 710.8eV) and
Cu (around 933.6eV), it is hard to make a further analysis due to the low
signal-to-noise ratio.
In the future, we will try to measure the samples again with more scan loops to
increase the signal-to-noise ratio or try to use the transfer vessel to prevent
the contamination from carbon in the atmosphere as much as possible, and
analyze the results by combining with other characterization such as H2-TPR
or EXAFS.
