Chemically controlled growth of porous CeO2 nanotubes for Cr(VI) photoreduction

Crystal facet and surface defect engineered low dimensional CeO2(0D, 1D, 2D) based photocatalytic materials towards energy generation and pollution abatement

“…Different mediators such as mineralizers, organic solvents, surfactants are used to kinetically control the 1D anisotropic crystal growth alongside other parameters like temperature, pH, concentration, etc. are also optimized for thermodynamically favoured 1D structure [69][70][71][72][73][74][75][76][77]104]. Zhao et al prepared single-crystalline nanorods via the hydrothermal method (140 o C for 56 h) by taking NH 3 .H 2 O as an alkaline agent without the use of any surfactant or capping agent followed by calcinations [69].…”

Controlled synthesis and magnetic properties of thin CeO2 nanotubes by a facile template-free hydrothermal method

“…It is generally accepted that these 1D materials may offer opportunities for investigating the dependence of optical, magnetic and electronic properties on shape, size and dimensionality. Since the carbon nanotubes were discovered by Japanese scholars Iijima [5] in the 1990s, because of the nanotubes provide a three different but interrelated area of the surface, the outer surface and the tube end, the scientific community has set off a craze for the research of nanomaterials with tubular structures [6][7][8][9].…”

Morphology Modulated Photocatalytic Activity of CeO2 Nanostructures for Selective Oxidation of Biobased Alpha‐Pinene to Oxygenates

“…These 4 f electrons are responsible for its unique electronic and optical structures, including the chemical and physical properties. The various CeO 2 based photocatalysts have been successfully explored in organic chemical synthesis, especially for oxidation and reduction related chemical reactions [21,22] . However, CeO 2 has a band gap width of 3.2 eV, which restricts its effective utilization in the visible light response range for organic synthesis reactions.…”

“…The various CeO 2 based photocatalysts have been successfully explored in organic chemical synthesis, especially for oxidation and reduction related chemical reactions. [21,22] However, CeO 2 has a band gap width of 3.2 eV, which restricts its effective utilization in the visible light response range for organic synthesis reactions. As a results, several strategies that are based on morphology and facets modulation using the nanostructuring synthesis route have been shown to yield CeO 2 catalysts material with improved light absorption.…”
