Abstract(J)自動車の排気ガス後処理には白金等の貴金属触媒が使用されるが,貴金属の枯渇が懸念されている.我々は,その代替材料として熱励起活性を持つ酸化チタンに着目した.これまでの研究により,酸化チタンが CO とアルデヒド類に対し有効な酸化性能を持つことが明らかにした.本研究では,カーボン粒子を触媒粒子表面に堆積させ,加熱温度,流量,酸化チタンの結晶構造を変えて微粒子(PM)の酸化性能を実験により明らかにした.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
