Abstract
Gold-based nanomaterials have received increasing attention in a wide range of energy, environmental and medical applications due to their unique physicochemical properties, chemical robustness, and distinct catalytic activities [1-5]. In this presentation, we mainly focus on the synthesis and modification of nanoporous Au as well as its promising energy, environmental and biological applications. The primary strategies for the fabrication of nanoporous gold, including chemical dealloying, electrochemical alloying/dealloying, and dynamic hydrogen bubble template approach, will be presented. The development of nanoporous gold based electrochemical sensors for the detection of biomarkers, contaminants, and food additives will be highlighted. In addition, the high catalytic activity of nanoporous gold towards the electrochemical reduction of carbon dioxide will be discussed.
