Ru-Based Plasmonic Catalysts for CO2 Methanation: Dissecting Thermal and Non-Thermal Contribution in Plasmon Photocatalysis

Abstract

The primary objective of this thesis is to study and optimise the light powered catalytic conversion of carbon dioxide to methane (Sabatier reaction) using plasmonic Ru-based catalysts, focusing on гnderstanding and leveraging both thermal and non-thermal contributions to plasmon photocatalysis. This goal is pursued through a multidisciplinary approach integrating precise synthesis, optical characterisation, and targeted catalysis experiments combined with in operando temperature monitoring.
