- Abstract
- The increasing levels of carbon dioxide (CO2) in our atmosphere demand innovative and efficient methods for its reduction. In this context, we present an advanced solar-driven photocatalyst, Pt-doped graphitic carbon nitride (Pt/g-C3N4), specifically engineered for enhanced photoreduction of CO2. Our findings highlight the dual advantage of Pt/g-C3N4: enhanced visible light absorption and electron-hole pair dynamics, ensuring efficient carrier separation. Notably, the CO and CH4 yields, when employing Pt/g-C3N4, surpassed those with the pristine g-C3N4 catalyst by factors of 3.1 and 4.3, respectively. Moreover, the Pt/g-C3N4 catalyst exhibited consistent high-efficiency of CO2 conversion over successive cycles, emphasizing the catalyst's robustness. This work underscores the potential of Pt/g-C3N4 as a viable tool against escalating CO2 levels, paving the way for a green and sustainable conversion of this predominant greenhouse gas into beneficial chemicals.
