Sivan claim that the methods used to distinguish thermal from hot carrier effects in our recent report are inaccurate and that our data can be explained by a purely thermal mechanism with a fixed activation energy. This conclusion is invalid, because they substantially misinterpret the emissivity of the photocatalyst and assume a linear intensity-dependent temperature in their model that is unrealistic.
西万声称,我们最近的报告中用于区分热效应和热载流子效应的方法不准确,我们的数据可以用一个具有固定激活能的纯热机制来解释。这个结论是无效的,因为他们严重误解了光催化剂的发射率,并在他们的模型中假设了一个不切实际的线性强度依赖温度。
