[求助] 求助：回答审稿人的问题

审稿人的问题：
Page 5: Line 25-41: The experimental description was vague without sufficient technical details. How the catalyst particles were immobilized on the glass plate? If it was, as the author described, “set” on a glass plate, I am afraid that the little magnetic fan, which was used to ensure the complete mixing of the reactor, would suspend the nanoparticles to be aerosols. However, if the authors meant that the catalyst was immobilized, it should be described explicitly. Maybe I am wrong, but to me it is less likely to immobilize 0.5 g particles on a 13.5 cm2 glass plate as a relatively homogenous thin film. If it was randomly stacked on the glass plate, its grain size and pore distributions would be very difficult to be controlled consistent from one experiment to another. The fan-mixing could eliminate the mass transfer limitation in the bulk air, but it may not be effective to minimize the intraparticle diffusion barrier (if you are not sure whether you system may be in an intraparticle-transport-limited regime). I understand that the objective of all the tests were to study the intrinsic chemical kinetics (i.e., photocatalytic activity), so the authors must convince the readers that their experimental designs were not affected by transport limitation or by the inconsistency of individual experimental conditions.

我在文中的描述：
0.5 g of the catalyst was set on a 13.5 cm2 glass plate and placed at the center of the 250 mL reactor. Then 0.5 ML chlorobenzene liquid was injected into the sealed reactor filled with air and allowed to evaporate with a small magnetic stirring fan. Illumination was initialized after it got to adsorption equilibrium. The small fan guaranteed the gases circulation inside the reactor.

其实我是直接将催化剂粉末放置在催化剂片上的。我能这么回答吗：
The catalyst particles were immobilized on the glass plate by setting on the frosted glass plate. The observations showed that no aerosols take place. It may be attributed to the big molecular mass of KLaTi2O6 (370g/mol).
