Abstract

In present paper, the fusion of metal nanocrystals on TiO2 nanowires is studied and utilized to synthesize bimetallic nanoparticles on nanowires. Cationic polydimethyl aminoethyl methacrylate (PDMAEMA) brushes are grafted onto TiO2 nanowires, and palladium nanocrystals are produced by polymer brush-bound PdCl42− and subsequent in situ reduction with NaBH4 in high density and low polydispersity. It is found that Pd nanocrystals of 2–3 nm starts to fuse even at 100 °C, but are apparently obstructed by the polymer brush matrix. Nanocrystal fusion speeds up instantly after polymer decomposition degradation at temperatures above 300 °C. By taking advantage of the polymer brush technique successive, templated uploading of different nanoparticles and fusion, Pd–Au bimetallic nanoparticles or alloys are formed on TiO2 nanowires. The results provide a novel method towards TiO2 nanowire supported (bi)metallic nanoparticles and have hinted at practical uses for elucidating the catalytic behavior of the composites.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
