<p class="MsoNormal" style="margin-bottom:8.0pt;line-height:150%"><span style="font-family:"Arial",sans-serif">The availability of renewable energy sources (solar and wind) provides opportunities to replace many traditional chemical synthesis methods by electrochemical
processes to achieve sustainable manufacturing, including direct ethanol fuel cells (DEFCs), hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) electrochemical production, and carbon dioxide (CO<sub>2</sub>) reduction reactions. However, the rates of many important
reactions involved in electrochemical processes are too slow and the selectivity of targeted products also needs to be improved. The key to solve these challenges is to gain fundamental understanding of reaction mechanisms and design better electrocatalysts.
<span style="color:black"> In this presentation, I will discuss three examples to control reaction selectivity via different strategies, including using element-intermediate-selectivity relationship, tuning
</span>the local chemical coordination between atomic metal catalyst and the support, and controlling the evolution of catalyst oxidation state during the reaction. </span><o:p></o:p></p>
