| Abstract |
Hydrogen is considered to be one of the most important energy sources to address the global environmental and energy crisis due to its high energy density and low environmental impact. There is a well-known volcano-type relationship between energetics and current density for hydrogen evolution reaction (HER) catalysts and Pt-based catalysts. The Pt-based catalysts located on the top of the volcano considered as the most effective ones. Nevertheless, the major drawback of Pt based catalysts is their high cost. So, it is significantly important to design and synthesize another metal-based efficient catalysts. In this study, mesoporous Rh has been employed for HER. It is expected to show highly catalytic activity because it has abundant exposed active sites and highly accessible surfaces. These advantages are expected efficient catalytic activity. The electrochemical performances of mesoporous Rh such as kineticsm electrochemical surface area, and durability was intensively studied. |
