Surface Science and Technology, Journal Year: 2023, Volume and Issue: 1(1)

Published: Dec. 20, 2023

Abstract To achieve the United Nations' Sustainable Development Goal (SDG7) of limiting global temperature rise to less than 1.5 °C, it is crucial reduce non-renewable energy sources and curb production greenhouse gases like CO 2 . In this context, graphitic carbon nitride (g-C 3 N 4 ) has emerged as a promising metal-free semiconductor photocatalyst for converting solar into clean fuels valuable chemicals. However, there are challenges associated with g-C , such high electron–hole recombination, low photocurrent generation, limited specific surface area, an absorption edge below 450 nm, which can be attributed arrangement monomeric units. This review focuses on recent developments in designing single catalyst through atomic-level doping tuning chemical properties. Various techniques, including nonmetal bi-nonmetal doping, well vacancy creation within polymer framework effect plasmonic nanoparticles, explored effective ways fine-tune polymer's conduction band (CB) potential, bandgap, structural The impact distribution molecular orbitals, density states (DOS), adsorption investigated using computational calculations based first principles functional theory (DFT). also examines influence photocatalytic reactions occurring CB, water splitting dioxide (CO reduction, their selectivity producing desired products. Last, summarizes current challenges. It provides future perspectives developing photocatalysts, emphasizing need address unresolved structural, electronic, chemical, optical properties advance sustainable solutions. Overall, hoped that will inspire further research unlock full potential photocatalysts contribute more future. Graphical
