The necessity for the development of new materials is the unceasing requirement for high energy conversion efficiencies for fuel cells and batteries and electrolyser applications in Canada. For this reason, an understanding of the fundamentals of many basic and crucial electrocatalytical reactions remains an important issue. Of various systems examined, O2 and CO2 reduction as well as NH3 and short chain alcohol oxidation are of particular technological interest. The most important characteristic is the efficiency of the material used for the electrochemical reactions. Detrimental side reactions can occur, such as the poisoning effect caused by irreversible adsorption of products/intermediates of the electrochemical reactions.

开发新材料的必要性是加拿大对燃料电池和电池以及电解槽应用的高能量转换效率的不断要求。因此，了解许多基本和关键的电催化反应的基本原理仍然是一个重要的问题。 在所研究的各种系统中，O2和CO2还原以及NH3和短链醇氧化具有特别的技术兴趣。 最重要的特征是用于电化学反应的材料的效率。可能发生有害的副反应，例如由电化学反应的产物/中间体的不可逆吸附引起的中毒效应。
