In our research, we explore the fabrication of porous GCN layers on modified substrates to improve mechanical stability and photocatalytic efficiency. The substrate surface was modified by laser engraving to create a rougher surface. The coatings were prepared using a wet ball-milled suspension of GCN, formulated with an oligomeric siloxane binder for adhesion control and camphor as a sacrificial pore-forming agent. The doctor blade technique was employed for deposi-tion, followed by controlled sublimation of camphor under reduced pressure to introduce porosity. Substrate modification was implemented to enhance adhesion properties. Structural and morphological analyses revealed that optimized porosity significantly improved light penetration and mass transfer, increasing photocatalytic activity. This work highlights the synergy between sub-strate surface engineering and tailored porosity in advancing the practical application of GCN coa-tings for environmental and energy-related technologies.
