Description
Summary:Molecular sensing and sustainable energy conversion are critical components in addressing electrochemical challenges and fostering the development of energy technologies. Within the realm of electrochemical processes, such as H2O2 sensing, hydrogen evolution reaction (HER), and CO2 reduction reaction (CO2RR), there is significant untapped potential for improvement through nanoscale light manipulation. One particularly promising approach is localized surface plasmon resonance (LSPR) enhanced electrochemistry. This innovative method leverages resonant plasmon relaxation to generate excited charge carriers, which actively engage in electrochemical reactions. In this review, we aim to shed light on recent advancements in plasmon-enhanced electrochemistry, with a particular focus on the fields of electroanalytical and electrocatalysis. We will highlight key studies and their contributions, emphasizing their role in paving the way towards a sustainable future for both molecular sensing and energy production.
