你讲的问题涉及两个过程，即焙烧过程的（ZnS、ZnO、SO2、O2）系统和还原过程的（ZnO、CO2、O2、CO）系统。根据吉布斯相律，所有烟气为一个相，固体中每种矿物为一个相，所有互熔的液体为1相。因此，焙烧过程中，如果不出现液相，则有ZnS、ZnO、烟气共3相；还原过程中，假设锌蒸气在炉内形成液相（实...
The sensor detects hydrogen concentrations down to 10 ppm in N2 at room temperature, whereas there is no response to O2. By exposing the sensor to air or O2, the conductance recovers to 95% after 20 s. The same group have also shown H2 sensitivity for Pt-coated ZnO nanorods97. A ...
Since there is an equal number of each element in the reactants and products of 2ZnS + 3O2 = 2ZnO*SO2, the equation is balanced. Balance ZnS + O2 = ZnO*SO2 Using Inspection Balance ZnS + O2 = ZnO*SO2 by inspection or trial and error with steps. Step 1: Count the number of eac...
ZnO和ZnS的晶体结构相似，熔点较高的是ZnO。理由是：同属于离子晶体，O2－半径小于S2－，故ZnO晶格能大(或离子键强)，熔点高。晶格能与离子键的键能和晶型有关，ZnS该是立方硫化锌，离子键的健能与电荷数和离子大小有关，电荷越多，离子越小晶格能越大，而O离子的半径比S小，所以ZnO晶格大。晶格...

由于ZnO的导带位置高于ZnS，当光激发时，ZnO导带中的光生电子会迅速转移到ZnS的导带上。同时，ZnS价带上的空穴会转移到ZnO的价带上，从而有效减少电荷载流子的复合。随后，聚集在ZnO价带上的空穴将H2O分子氧化为O2和H+，而聚集在ZnS导带上的电子则将CO2分子还原为CO。图2展示了ZnO/ZnS杂化材料的能带结构。通过构建...

试题分析:(1)设闪锌矿中ZnS的质量为x,杂质为y 2ZnS+3O2=2 ZnO+2SO2 x/97 x/97 有x+y=1.56g 81x/97+y=1.32g 解得x=1.455g,y=0.105g,所以样品中w(ZnS)=1.455g÷1.56g×100%=93% (2)设浓硫酸被还原的产物中S的化合价为x。56、根据题意过量的硫酸用碱滴定,则过量的硫酸n(H2SO4)= n(...
