传递到达催化剂表面的量不同,因而导致光催化反应效率的不同.人们通过实验发现,随着污染物初始浓度的增加,光催化发应速率增大[1-3],但是当污染物浓度增大到一定数值时,光催化反应速率的增大逐渐变慢,甚至不变[2,3].可见,光催化反应受到污染物质量传递的限制.随着污染物浓度的增加,污染物向催化剂表面传递的量增加...
Reaction of NO2, NO, O2, and H2O to form HNO2 «on:January 06, 2018, 09:51:30 PM » This is translated from a different language, so the nuances of the problem might be altered, but the essentially, the problem is this: ...
O2/CO2燃烧碱金属准东煤The influences of reaction temperature,ash,minerals and reaction atmosphere on the NO2 reduction behavior were investigated in a fixed bed reaction system to explore the mechanism of NO2 reduction under O2/CO2 combustion condition.Experimental results indicate that NO2 reduction ...
With an HZSM-5 molecular sieve as catalyst, NO2 to toluene ratio of 2:1 (molar ratio), O2 pressure0.5 MPa, controlled reaction temperature of 45℃, and reaction time of 3 h, the reaction conversion rate was 100% andselectivity for para-nitrotoluene was 45%, which is higher than when ...
NO2 + Cl reaction and a stratospheric cooling slows the NO + O3 ??? NO2 + O2 reaction, leaving more NOx in the form of NO. The slightly positive trends in ozone estimated from ground- and satellite-based data sets are also consistent with the decrease of NO2 through the NO2 + O3 ...
于是, 人们 做出了很多努力, 以便能够在金单晶表面上可控地 制备化学吸附的原子氧物种, 并找到了一些行之有 效的方法, 如 O2 的直接热裂解[7,8],在纯氧气中微波 放电[9],极低温度下利用光子或电子轰击来活化物理 吸附的 O2 [10],O+溅射[11,12],暴露能够沉积氧原子的 气体(如臭氧)[13~17],以及电...
Part 2.—The reactions SF + X (X = O, N, NO2, NO and O2) The kinetics of reactions involving ground-state SF (X2Π) radicals have been studied in a discharge-flow system at 295 K using mass-spectrometric detection. The SF radical was generated by the reaction of F atoms with ...
For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis () or brackets []. How To Balance Equations Balance any equation or reaction...
