Abstract
Driving chemical reactions by use of sunlight is of great importance for a sustainable future. Pd-based catalysts are commonly employed in thermal catalysis for various chemical reactions such as hydrogenation and coupling reactions. However, very few reports were related to Pd for photocatalytic coupling reactions. In this work, a facile method was developed to synthesize ultra-small Pd nanoparticles anchored on ultrathin crystalline graphitic carbon nitride (g-C3N4) for photocatalysis. Monodisperse Pd nanoparticles with a diameter of about 3 nm were dispersed on ultrathin crystalline g-C3N4 uniformly. The prepared Pd/g-C3N4 catalyst could take the advantages of the unique properties of ultra-small Pd nanoparticles and ultrathin crystalline g-C3N4 and thus exhibited markedly enhanced photocatalytic performance toward Suzuki–Miyaura coupling reaction under visible light irradiation. The preparing method could also be extended to the synthesis of Ru/g-C3N4, Pt/g-C3N4, and Ag/g-C3N4.
