“…When the decomposition temperature of the second metal precursor is reached, it will be decomposed and formed on the surface of the first metal nanoparticle, thereby forming a bimetallic nanoparticle. For example, synthesis of bimetallic titanium complexes M-Ti-O (M = nickel-Ni, Cobalt-Co, Manganese-Mn) from cobalt, manganese and nickel metal precursors by using the thermal decomposition method were reported in the literature [98]. In addition, the thermal decomposition method of synthesis has been used to synthesize Pd-Ir, [59], Co-Mn [99], Pd x Ni y [100], Ti/Ce-Sb-SnO 2 NFs and Pd-Ag/C bimetallic nanoparticles [101].…”

The manipulation of matter at the atomic level (nanotechnology) has experienced an explosion in research interest in recent years. Bimetallic nanoparticles are vital due to their high biocompatibility, stability and comparatively less toxicity. The synthesis methods that include physical, chemical and biological methods are explored and explained in detail, along with their advantages. They have a wide range of applications due to their synergistic properties including biological applications (in medicine and agriculture), environmental application (in water treatment and removal of toxic contaminants), engineering application (in nanosensors, nanochips and nano-semiconductors) and chemical and physical application (in optics, catalysis and paints). The green synthesis approach is a promising method of synthesis that can give rise to more biocompatible and less toxic bimetallic nanoparticles due to increasing environmental pollution. However, despite these interesting attributes of bimetallic nanoparticle, there is still much work to be done to improve the biocompatibility of bimetallic nanoparticles because of their toxicity and potentially hazardous effects.

“…This system is only activated by UV light, which has limited its application. This limitation can be resolved by modifying a TiO 2 nano-photocatalyst for instance through doping [14,15], grafting [16], solid solution, semiconductor coupling, floatability amelioration, immobilization and magnetic separation [17][18][19][20][21][22][23][24][25][26][27][28].…”

In this study, a composite bearing titanium carbide (TiC), titanium dioxide (TiO 2 ), polyvinyl alcohol and xylan (TiC@C-anatase/rutile@polyvinyl alcohol/xylan) was synthesized and applied as a photocatalyst for the degradation of bromophenol blue (BPB) solution through several steps. Nanostructure of TiC and TiO 2 in the anatase and rutile phases was obtained through heat treatment of TiC at different times and temperatures (TiC@AR) which led to a reduction in energy bandgap from UV to visible light, in addition to the enhancement of the surface activity. After TiC@AR polymerization by xylan and polyvinyl alcohol and obtaining TiC@AR/PX, the energy bandgap reduced to IR range (52% of the sunlight) while showing an enhancement in the surface activity. The photocatalytic activity of the compounds was tested by studying the decomposition of BPB solution under visible light. The result illustrated the ability of TiC and TiC@AR to decrease the concentration of BPB after 150 min by 35% and 37%, respectively, while this reduction was 72% for TiC@AR/PX. Considering the effective parameters, the energy bandgap and the surface layer played key roles in photocatalytic degradation.

“…TiO 2 nanoparticle is one of the most proper and popular semiconductors whose applications cover diverse industrial areas including photocatalysis [1,2], thin-lm, sunscreen, photovoltaic, electrodes [3,4], sensors [5,6], and drug delivery [7,8]. In this regard, TiO 2 nanoparticle have been prepared through different methods, including sol-gel [9], inverse micelle [10,11], hydrothermal [12], straight oxidation [13][14][15], chemical vapor deposition [16][17][18], physical vapor deposition [19][20][21], electrochemical accumulation [22][23][24], sonochemical [25], microwave [26][27][28], and organometallic complex compounds [29][30][31][32][33][34]. However, almost all of the mentioned methods require high temperature (usually more than 500) [35].…”

TiO2 nanoparticles in the brookite phase were synthesized within an environmentally friendly method by magnetized water obtained by the US-patent magnetizing device (US10507450B2), which changes the properties of all types of the solvents with no limitation (protic or aprotic). Furthermore, this study is the first report on the synthesis of brookite TiO2 nanoparticle through magnetized water at room temperature. The procedure was tested by five different water; ordinary, 15, 30, 45, and 60min-magnetized water. The products were analyzed by various techniques including XRD, FESEM, ICP, BJH-plot, t-plot, Langmuir plot, BET, TEM, and FTIR. The result showed that the products obtained from 30 min-magnetized water were the most properly indexed TiO2 brookite phase with high surface activity. This sample could be a suitable green photocatalyst.
