📄 Abstract（原文）
Energy from renewable sources, such as green hydrogen, stands out as an alternative with high potential to meet the significant global energy demand. New materials are being developed for use in catalytic hydrogen photogeneration. However, few works report precise control of the composition and structure of nanoparticles and their effects on water decomposition. The active sites available in both the semiconductor and the adsorbed nanoparticles significantly improve light absorption and reduce electron/vacancy pair recombination. Here, hydrogen was produced using TiO2 nanotubes decorated with plasmonic bimetallic nanoparticles. The samples were characterized by Raman spectroscopy, transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma optical emission spectrometer (ICP OES), X-ray excited photoelectron spectroscopy (XPS), UV-Vis, and N2 adsorption-desorption. The TEM images showed the formation of nanotubes with an external diameter of about 55 nm, with anatase being the predominant phase. The photocatalysts generally showed high production rates, particularly for AuPd-TiO2, with a rate of around 4000 μmol g–1. The results of this work show that the material is a good option for producing clean energy, providing future solutions for sustainable development.
