Pd/Au bimetallic nanoparticle-anchored BiVO₄/TiO₂ nanotube arrays toward efficient photoelectrocatalytic Suzuki-Miyaura reactions

Owing to the high efficiency and atom economy of homogeneous palladium-catalyzed Suzuki-Miyaura cross-coupling (SMC) reactions, they are considered effective for C-C bond formation. However, the feasibility of this process is limited by the difficulty in separating the catalyst and the high energy consumption. Thus, in this study, to solve these issues, a uniform dispersion of ultrafine Pd and Au nanoparticles was successfully anchored on the surface of BiVO4/TiO2 nanotube arrays. Benefiting from the synergistic effect of effective charge carriers separation, wide spectral response, strong component interactions and abundant active centers, the unique Pd/Au bimetallic nanoparticle-anchored BiVO4/TiO2 nanotube arrays exhibited excellent photoelectrocatalytic activity and good reusability in SMC reactions of aryl boronic acids with substituted aryl halides under ambient conditions.
