Web化学反应速率是指表示化学反应进行的快慢。通常以单位时间内反应物或生成物浓度的变化值（减少值或增加值）来表示，反应速度与反应物的性质和浓度、温度、压力、催化剂等都有关，如果反应在溶液中进行，也与溶剂的性质和用量有关。其中压力关系较小(气体反应除外），催化剂影响较大。
Web0 reacties. Een mmol is een millimol. Dat is een duizendste mol. Het werkt op precies dezelfde manier als een mg een milligram is, een duizendste gram. En een mm een millimeter is, een duizendste meter. Zo ook is een ms een milliseconde, een duizendste seconde. En zo zijn er nog veel meer, maar die zijn in het dagelijkse leven wat minder … Web14 apr. 2024 · 为了验证 H2O2 能够电解生成且可在电解液中积累，研究人员将Co-SAs/NC负载在碳布上进行恒电位电解，可获得 38.1 ± 1.5 mmol gcat-1 h-1 （ 17318 ± 682 mmol gCo-1 h-1 ）的 H 2O2 产率以及72.1%±4.2%的法拉第效率。 该研究有利于设计和发展两电子氧还原电催化剂。 研究工作得到国家自然科学基金、中国博士后科学基金面上项目和 …
WebThe H 2 production at the rate of 1280 μmol h −1 and 80 μmol h −1 were obtained using 50 mg of the photocatalyst (25.6 × 10 3 and 1.60 × 10 3 μmol g −1 h −1) under UV and visible-light radiations and in the absence of any co-catalyst, respectively (Fig. 8 b).
