“…We observed that the pattern of the precursors consisted of five primary characteristic peaks at 2u values of 10.5 , 24.3 , 28.5 , 31. 6 , 48.6 , respectively It was reported that these peaks corresponded to the layered structure of nanotube titanium oxide [12]. The structure has been assigned to A 2 The present of Na + in prepared alkali titanate nanotubes should be associated with two mechanisms: (i) Na + only adsorbed on the tube surface and/or (ii) structural Na + (which means the cations belong to the tube).…”

The objective of this study is to investigate the role of Na + content in the morphology evolution of TiO 2 nanoparticles prepared by hydrothermal approach. Various TiO 2 morphology from 0-dimensional (0D) nanoparticles to 1-dimensional (1D) nanorods were synthesised by hydrothermally treating the alkali titanate nanotubes with different Na + content. The XRD patterns show the phase transformation and crystallographic nature of alkali titanate nanotubes are strongly dependent on the Na + content, the cation exchange of Na + by H + ion exchange affects the crystallinity of the tubes and causes disorder of the interlayers of nanotubes. The SEM and TEM images confirm that Na + rich titanate nanotubes were thermally stable. Moreover, BET measurements revealed that the Na + content plays an important role on the specific surface area of formed TiO 2 nanoparticles. The photocatalytic activity of the TiO 2 nanoparticles was characterised via the decomposition rate of an aqueous solution of methyl orange (MO) under UV light irradiation. The TiO 2 nanoparticles prepared by hydrothermally treating the alkali titanate nanotubes with no Na + content has a surface area of 55.1 m 2 /g with nearly 100% photodecomposition of MO in 20 min.

In this work, a metal‐organic frameworks‐based porous carbon was explored for glucose oxidase immobilization and glucose sensing. ZIF‐67 was chosen as the precursors for the calcination treatment. The formed Co nanoparticles induced the graphitization of the carbon during the carbonization, resulting in a good conductivity. The followed HCl treatment partly removed the formed Co nanoparticles to give a larger specific surface area of the porous carbon due to the generated space voids from the dissolved Co nanoparticles. The resulting MOFs‐derived porous carbon show an improved loading performance toward glucose oxidase, and fast electron transfer was also demonstrated. This work proves the MOFs‐derived porous carbon as a novel and outstanding platform for the enzymatic electrocatalysis for the sensors and energy conversion devices.
