Multifunctional catalysts with photodegradation of organic contaminants and electrocatalytic hydrogen evolution are extremely urgent. In this work, a unique MoS2 hollow microsphere with a diameter of 1.5 μm was fabricated without adding any spherical template by an improved hydrothermal process. Interestingly, the MoS2 hollow microspheres with introduction of the NiS and Pd nanoparticles greatly restrain recombination rates of electron‐hole pairs, resulting in the outstanding photocatalytic activity. The RhB removal rates of the MoS2 hollow microsphere and the NPMS composites were 7 and 10 times higher than that of pure MoS2, respectively, for the high concentration of macrocyclic contaminants under visible‐light illumination. Furthermore, the optimal robust NPMS hybrids exhibite a lower overpotential of 100 mV (at 10 mV cm−2) and a smaller Tafel slope of 50 mV dec−1. The unique structure composite catalysts possess more exposed active sites and defects to enhance the catalytic activity for HER and removal of organic pollution.

“…Figure shows the transmission electron microscope (TEM) image of as-prepared F-TiO 2 (B) (a), F-TiO 2 (B)/MWCNT (b), and F-TiO 2 (B)/SWCNT (c). As can be seen in Figures b,c and d,e, MWCNTs and SWCNTs have been filled between the branches of 3D hedgehoglike F-TiO 2 (B) while some parts of it were not filled . In F-TiO 2 (B)/CNTs nanocomposites, MWCNT and SWCNT assisted as a catalyst support for increasing the reactive surface area of F-TiO 2 (B) and the synergistic photocatalytic and sonophotocatalytic effect …”

The present study describes the preparation of hedgehoglike F-doped titanium dioxide bronze (F-TiO(B)) and its nanocomposites containing single-walled and multiwalled carbon nanotubes (SWCNTs, MWCNTs) by using combined ball milling-hydrothermal processes. Then, sonophotocatalytic and photocatalytic degradation of malachite green (MG) dye from aqueous solution using prepared materials was performed. The results show that F-TiO(B)/SWCNT displays a good sonophotocatalytic and photocatalytic performance among other products under visible light. In addition, they indicated that the efficiency of malachite green degradation is more than 95% and 91% for sonophotocatalytic and photocatalytic methods, respectively. Also, they demonstrate that the photocatalytic efficiency of catalysts increases in the presence of ultrasound and the sonophotocatalysis process followed a second-order kinetics. The catalysts have been characterized by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), UV-vis diffuse reflectance spectroscopy, and energy-dispersive X-ray spectroscopy (EDX). The analyzed data confirmed the presence of CNTs and fluorine (F) as dopant in all nanocomposites. The presented hybrid method reduced the band gap from 3.02 eV for F-TiO(B) to 2.7 eV for F-TiO(B)/SWCNT nanocomposite.

“…Pore volume can contain large amounts of Li + . 33 Surface of BC has a hydroxyl group, which is liable to form hydrogen bonds with PF 6 − and other anions. The interactions hinder the movement of anions in the electrolyte and increase the number of transferred lithium ions and high specific surface area, which are desired during the charge–discharge.…”
