最近审稿意见回来了
①. 我用的PBE泛函,算的所有气体物理吸附的吸附能都很小,所以就用DFT-D3方法校正了一下。结果审稿意见说我泛函选择不正确?我没太弄明白他的意思,是不用进行校正吗?
计算内容:CO2在Ni(111)上的吸附
审稿意见:原文:Incorrectchoice of DFT functional for performing the calculations. For example, CO2adsorption energetics by PBE are completely off. In fact, no existing functional can predict it correctly and special correction needs to beincorporated.
[size=14.6667px]计算时DFT泛函的选择不正确。[size=14.6667px]例如,PBE对CO2的吸附能量完全关闭。[size=14.6667px]事实上,没有任何现有的功能可以正确地预测它,需要结合特殊的校正。[size=14.6667px]他还说需要特殊的校正。到底应该咋弄啊?
[size=14.6667px]②. 接上面那条审稿意见,他这条审稿意见还有后半句:EvenCHX dissociation numbers are off, compared to the literature.
CHx的解离数是什么?我的文章要用到Ni(111)的数据,但是Ni(111)都要被算烂了,有很多可用的参考数据,我的算完以后还专门跟文献里的活化能对比了(数据对比的表格已经放在了SI中),基本都是一样的,最大的差别可能有0.2eV(泛函是相同的)。我认为这是正常的。就很不理解他句话的含义。
[size=14.6667px]综上,整条审稿意见是:Incorrectchoice of DFT functional for performing the calculations. For example, CO2adsorption energetics by PBE are completely off. In fact, no existingfunctional can predict it correctly and special correction needs to beincorporated. Even CHX dissociation numbers are off, compared to theliterature.
