AbstractRemoving volatile organic compounds (VOCs) from the environment via photocatalytic reactions is highly effective for achieving clean air. While Pt deposition on TiO₂ surfaces is recognized as a viable catalytic method, understanding Pt interaction, dispersion, and facet optimization remain incomplete, leading to suboptimal performance and cost inefficiencies. This study investigates Pt adsorption on rutile TiO2 surfaces, focusing on the (101) and (110) facets. It reveals that Pt attachment is strongly influenced by surface facet and Pt ion species. The (101) facet exhibits superior adsorption for Pt ions, such as Pt(OH)2 and PtCl5
