Abstract
As the world is facing increasing challenges in the field of energy crisis
and environmental pollution, the use of renewable energy to control
environmental pollution is of high priority. As an inexhaustible and
environmentally friendly resource, solar energy is considered the most ideal
power, which enables photodegradation to be a favorable technology for
controlling environmental contamination. Thus, photocatalysis, especially
semiconductor photocatalysis, becomes popular due to the advantages of using
renewable resources, cost-effectiveness, safety, and comparatively high
efficacy of water pollutant removal.
Graphitic carbon nitride (g-C3N4 or gCN) has drawn great attention
recently because of its visible light response, suitable energy band gap, good
redox ability, and metal-free nature. gCN can absorb visible light directly,
therefore has a better photocatalytic ability under solar irradiation and is more
energy-efficient than other semiconductors. However, pure gCN still has the
drawbacks of insufficient light absorption, small surface area and fast
recombination of photogenerated electron and hole pairs. In this thesis, the
visible light harvesting and photoelectrochemical properties of bulk gCN were
expanded by hybridization with noble metals including gold (Au) and silver
(Ag) nanoparticles (NPs) using different approaches
