Oxygen group oxygen, sulfur, selenium, and tellurium
氧族元素氧Besides, scan rate and cycle period also affect the result ; co - deposition of dualistic oxide is a focus of research, as an element in the same group, ir is selected. deposition rate of composition is decreased by the adding of ir composition, and when the proportion of ir exceeded 50 %, composition procession can be ceased. but cooperation of ir and ru oxide can highly increase the specific capacitance of active material ; annealing treatment under a certain temperature can help to change the hydrate ru composition into mixture state ru oxide, accordingly increase the stabilization of active material
研究表明:電解液的配製過程中,氯化釕濃度、溶液ph值、陳化時間、溶液溫度對電鍍效果均有影響,其中溶液ph值是最主要的影響因素;在儀器的使用條件探索中,理論結合實驗確定了本電鍍液體系循環伏安電勢窗的理想范圍,並發現循環伏安掃描速度和掃描周期對電鍍結果也有較大影響;混合氧化物的共沉澱是目前研究熱點,在此選用與釕同一族的銥作為共沉澱元素,銥的加入會阻礙氧化物的沉積速度,銥的比例超過50 %會使沉積作用停止,但是二元氧化物的協同作用使沉積的活性物質比容量大大提高;一定溫度下退火后處理作用會使水合釕化物轉變成混合價態的氧化釕,從而提高活性物質的穩定性。It will melt in a certain range of melting points, but it has no definite melting point. soft pitch has no thermal effect when solidified
瀝青組分極為復雜,大多數為三環以上的芳香族烴類,還有含氧、氮和硫等元素的雜環化合物和少量高分子炭素物質。Selective oxidation of secondary alcohols by halogen - based oxidants
