Adsorption properties of arsenic on sulfated TiO2 adsorbents

Effects of gas phase composition on competitive adsorption properties of formaldehyde on titanium dioxide-supported platinum in single and mixture compositions

“…The core level of O1s in both pure TiO2 and Pt@TiO2 (Fig. 3c and e) also revealed the existence of two types of oxygen species including lattice oxygen (OI: 530.5 eV) and surface hydroxyls (-OH (OII): BEs of 531.6 and 531.7 eV in TiO2 and Pt@TiO2, respectively) (Lee et al, 2019;Zhang et al, 2022a). Additionally, the increase in the content of OH (OII) species (e.g., from 35.8% (pristine P25) to 43.4% in the Pt-doped TiO2) supports the possibility that the impregnation of Pt species might change the electronic environment for surface hydroxyl groups.…”

Effective Removal of Ni(II)ions from Aqueous Solutions Using Low-Cost, Eco-Friendly Natural and Modified Potato Peels

“…Adsorption methods are increasingly popular due to their simplicity, inexpensive, minimal energy consumption, and recycle [16]. For water bodies with high treatment capacity and low metal ion concentrations, the removal technique can successfully adsorb contaminants without introducing new pollutants to the water [17]. The deposition of adsorbate molecules on the adsorbent surface is the foundation of adsorption methods, which involves several different chemical and physical reactions.…”

Fabrication of a hybrid phase TiO2/g-C3N4 heterojunction composite with enhanced adsorption and photocatalytic degradation of MB under visible light

“…16 Therefore, many researchers have attempted to modify TiO 2 to improve its adsorption and photocatalytic performance. The commonly used modification methods include: (1) modification of the catalyst surface, (2) doping with non-metal elements; 17 (3) loading with metal nanoparticles, 18 (4) compositing with a semiconductor, 19 and (5) enlarging the specific surface area and active area, 20 such as carbon nanotubes 21 and graphene oxide (GO). 22…”
