“…Hence, a simple and inexpensive gravity separation method can be employed to isolate the α-TiP material. The production of α-TiP from ilmenite beach sand is operationally a lot simpler and requires fewer chemicals than the production of many inorganic phosphate materials 35 and TiO 2 . 34 Therefore, catalytic materials based on α-TiP should be more economical and environmentally friendly.…”

A simple hydrothermal method was developed for the synthesis of Ag supported on α-titanium bismonohydrogen orthophosphate monohydrate, Ag@α-Ti(HPO4)2·H2O (Ag@α-TiP), using ilmenite (FeTiO3) mineral sand. The prepared nanoparticles (NPs) were characterized using powder X-ray diffraction, high-resolution transmission electron microscopy, energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and diffuse-reflectance spectroscopy. The catalytic efficiency of Ag@α-TiP NPs in the reduction of 4-nitrophenol (4-NP) to 4-aminophenol with sodium borohydride (NaBH4) in the presence/absence of ultraviolet–visible (UV–vis) radiation was examined. The reduction rate increased when Ag@α-TiP was present in the reaction mixture. The catalytic efficiency was further enhanced when the reaction mixture was exposed to UV–vis light. An ab initio molecular dynamic approach, coupled with slab model density functional theory (DFT) calculations, was used to find the optimal geometry for the model catalyst Ag4@α-TiP. The formation enthalpies and binding geometries for 4-NP and 4-nitrophenolate ion (4-NP–) on Ag4@α-TiP were calculated using DFT.
