摘要：
A Co/HTNT catalyst is developed by immobilizing Co on the surface of titanate nanotubes. The microstructure and composition of the catalyst are investigated with atomic absorption spectroscopy (AAS), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), Fourier transform infrared spectrometer (FT-IR) and X-ray photoelectron spectroscopy (XPS). The developed Co/HTNT catalyst shows great performance in catalyzing NaBH4 hydrolysis. The hydrolysis of 25 mg NaBH4 catalyzed by 50 mg Co/HTNT in 10 g NaOH solution (12.5 wt%) provides a hydrogen production rate of 1.04 L min-1 gCo 30 degrees C, and the activation energy of the reaction is 29.68 kJ mol-1. The high catalytic activity and economical property make this catalyst a promising choice for on-site hydrogen production from NaBH4 hydrolysis. (c) 2021 Hydrogen Energy Publications LLC.
