“…[280,281] TiO 2 has attracted much attention due to its high oxygen precipitation potential, wide redox stabilization window, and good chemical stability. [282,283] But the weak adsorption of *OH on TiO 2 limits 2e − WOR activity. [284,285] The introduction of heteroatoms with strong *OH adsorption into metal oxides is a promising approach.…”

Hydrogen peroxide (H2O2) as a green oxidizing agent is widely used in various fields. Electrosynthesis of H2O2 has gradually become a hotspot due to its convenient and environmentally friendly features. Single‐atom‐site catalysts (SASCs) with uniform active sites are the ideal catalyst for the in‐depth study of the reaction mechanism and structure‐performance relationship. In this review, we summarize the outstanding achievements of SASCs in the electrosynthesis of H2O2 through 2e− oxygen reduction reaction (ORR) and 2e− water oxygen reaction (WOR) in recent years. Firstly, the elementary steps of the two pathways and the roles of key intermediates (*OOH and *OH) in the reactions are systematically discussed. Next, the influence of the size effect, electronic structure regulation, the support/interfacial effect, the optimization of coordination microenvironments, and the SASCs‐derived catalysts applied in 2e− ORR are systematically analyzed. Besides, the developments of SASCs in 2e− WOR are also overviewed. Finally, the research progress of H2O2 electrosynthesis on SASCs is concluded, and an outlook on the rational design of SASCs is presented in conjunction with the design strategies and characterization techniques.This article is protected by copyright.

“…Unlike the previous report by York R. Smith et al carried out by exposing the electrolytic setup to visible light, S. Huo et al reported electrochemical anodization of Ti performed under exposure to UV light. [97] The anodization system comprised of two-electrode setup wherein Ti foil and graphite sheet served as the anode and cathode, respectively. Electrochemical anodization was conducted in Gen-3 electrolyte under 60 V for 1 h. The anode was illuminated via UV lamp (5.8 mW/cm 2 at incident wavelength of 365 nm).…”

“…[96] The synergistic coupling of light-assisted anodization with a reduction in ambient pressure doubled the growth rate. [97] Unconventional substrates with uneven or patterned substrates were also used for the formation of desired pattern of the TiO 2 NTs to be formed. [102][103][104]106] Furthermore, different shapes of anodes, such as tubular and foam type, were used for the anodization purpose.…”

Over the past couple of decades (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020), titania (TiO 2 ) nanotubes (NTs) have been prepared by anodization techniques. The architecture of TiO 2 NTs is predominantly dependent on the potential, current density, electrolyte and time, in addition to other few minor factors. This review is about the state-of-the-art formation of TiO 2 NTs involving anodization technique. In fact, the principal motive is to briefly discuss the slight variations involved within the anodization technique in terms of applied potential and/or applied current density and the resultant outcome. An initial overview of the technique is given so as to understand the beauty of the reactions when variations are incorporated. A minute alteration in the conventional anodization technique results in the formation of highly different morphological features. There are about 30 different miniscule modifications in the anodization processes that have been reported, thus, far. The review primarily introduces and outlines the various anodization techniques involved in growing TiO 2 NTs and the consequent variations arising from these introduced variations. This review is a tribute to the bountiful and fruitful researches based on modifying anodization that was conducted in the recently passed bi-decades.

Sub‐nanometer titanium‐oxo cluster‐polymer nanocomposites for elastic, transparent UV‐resistant films and nano‐coatings

Core‐shell inorganic‐organic hybrid nanocomposites, Ti‐PMMAs are constructed applying the titanium‐oxo cluster (Ti6O4(BrC[CH3]2COO)8(OiPr)8, TiO; iPr = isopropyl) as quasi‐spherical initiator for ATRP (atom‐transfer radical polymerization). Confirmed by UV‐Vis measurements and mechanical test, Ti‐PMMAs inherit the properties of both TiO cluster and polymers and show outstanding UV‐proof performance, high visible light transmittances, and excellent mechanical properties and processabilities. The elasticity and toughness of TiO‐polymer nanocomposites can be further optimized by simply tuning the polymer composites during the ATRP reactions. The admirable processability of the hybrid materials render us the capability to produce uniform nano‐coatings of Ti‐PMMAs and TiO2 with thickness approaching to a challenging length scale, 10 nm.
