Abstract

Clean graphene offers strong potential for a wide range of energy applications, including storage, conversion, harvesting, and catalysis. Ongoing efforts to preserve its purity are essential for advancing sustainable and efficient technologies. Although chemical vapor deposition can produce large, high-quality graphene sheets, scaling the method for industrial use remains challenging. Issues with film uniformity and reproducibility often arise, particularly in quartz furnace systems, where unintended particle deposition can affect growth dynamics and material properties. This study investigates how these contaminants develop and traces their origins. It also proposes practical modifications to quartz furnace designs to minimize impurities and achieve more consistent large-area films. Detailed analysis using SEM, XPS, and Raman spectroscopy provides clear insight into the structural and chemical features of both as grown and transferred graphene.
