氧还原反应(Oxygen Reduction Reaction)基础
为了更深入地理解文献中所出现的各种电化学方法和指标背后的物理意义,笔者对使用到的基本电化学知识做了一个总结。虽然笔者努力保证所整理知识的正确性(添加引用),但由于笔者水平所限,难免错漏,望各位老师同学不吝赐教!

Santos-Koper-Schmickler电荷转移模型
传统电化学主要关注溶剂内变化,而现代电化学将关注重点转移到了电化学界面,即电极与溶液界面。而电荷(电子/质子)转移是电化学界面过程所关注的重要过程。
Green函数在量子物理中定义与广义定义的联系
在物理中可以引用Green函数求解下列形式的线性微分方程
\[[z-\hat{L}(\mathbf{r})]u(\textbf{r}) = f(\mathbf{r})\]The Application of Titanium for Photoreduction of Carbon Dioxide
ABSTRACT
Greenhouse gas emission mostly accounts for global warming effect, hence the urgency to realize $\text{CO}_{2}$ removal efficiently and harmlessly to the environment. Base on all of these requirements, utilization of abundant solar energy to achieve $\text{CO}_{2}$ reduction seems the be the best choice. In this review, mechanisms of $\text{CO}_{2}$ photoreduction is briefly introduced, including electrochemical potential analysis and chemical reaction mechanism. Efficiency measurements in this filed are summarized, mainly divided into two groups: catalyst-based measurement and light-based measurement. Applications of $\text{TiO}_{2}$ on $\text{CO}_{2}$ reduction will follow. Subsequently, the modifications on $\text{TiO}_{2}$ specifically for its efficiency and selectivity are discussed in details.

量子物理中的Green函数定义及其应用
在经典物理中,Green函数主要被当做一种求解线性微分方程数学物理方法来使用。在量子物理中,其定义稍显“不同”:
\[\hat{G} = (E-\hat{H})^{-1}\]当然其本质还是求解线性微分方程,关于它们之间的联系,详见博客文章:量子物理中Green函数与其广义定义的联系。在这里,我们先看看Green函数在量子物理中是如何被定义的。
