“…Wood template slightly in uenced the formation of nanoparticles and rutile phase content existing in the TiO 2 . Similar result has been reported by Sun (Sun et al, 2016). Charge separation of mixed-phase TiO 2 nanoparticles are signi cantly better than simple mixtures of single-phase nanoparticles due to the close contact of their heterogeneous junction.…”

Biomorphic TiO 2 photocatalysts with hierarchical porous structures by templating with different size scales of wood processing residues (lignocellulose, wood our, and solid wood as biological templates) through a simple sol-gel method is proposed for photocatalytic degradation applications. Compared with templatefree TiO 2 , the biomorphic TiO 2 had a good adsorption capacity and photocatalytic performance with methylene blue (MB) and phenol. The lignocellulose-templated TiO 2 reached adsorption equilibrium within 60 min because of the hierarchical structure of the complex interlaced wood. It exhibited 98.9% and 84.3% degradation of MB and phenol within 60 min under visible light conditions. The multiscale structure of the wood templates enhanced light absorption and mass transfer e ciency due to the presence of additional surface hydroxyl groups and a reduced bandgap. This research proposes a convenient synthesis method to obtain biomorphic TiO 2 using wood residues, and construct the physical-chemical interaction between wood and TiO 2 to enhance visible light response and transfer of photogenerated charge carriers.

A novel cellulose/TiO2/β-CD hydrogel with high photocatalytic antibacterial activity and sustained release of drug was prepared. TiO2 sol with a diameter of about 9 nm in this hydrogel was the photoantibacterial agent. β-CD can significantly enhance photoantibacterial activity and the sustained-release effect of this hydrogel. The structure and property of this hydrogel composite were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Escherichia coli and Staphylococcus aureus were selected as model bacteria to evaluate the antibacterial activity of the composite hydrogel under natural light irradiation and darkness, respectively. The in vitro release experiment used curcumin as a model drug in PBS buffer solution. The influence of β-CD on the antibacterial activity and sustained-release effect of the composite hydrogel was investigated. The results showed that the hydrogel composite presented a good photoantibacterial property, while the antibacterial activity can be neglected under the condition of no light. The complete release of curcumin from the composite was achieved after 120 h. Therefore, the hydrogel system has the characteristics of low cost and high effect, which could be used for an antibacterial sustained-release material.

A novel TiO 2 hydrogel cage model was built for the removal of methylene blue (MB), an organic pollutant. This TiO 2 hydrogel cage was prepared with the biomass materials of hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and this hydrogel cage structure was characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The contents of the encased TiO 2 and its swelling properties with different CMC proportions of this hydrogel cage were studied to obtain a suitable crosslinking network structure and optimal synthesis conditions. Compared to an equivalent amount of pure TiO 2 , the much higher removal efficiency of MB with our prepared TiO 2 hydrogel cage was attributed to the synergistic effect of the photocatalytic degradation for TiO 2 and the adsorption enrichment for cellulose hydrogels. Furthermore, the adsorption kinetics of the intraparticle diffusion model were used to study the adsorption enrichment process of the TiO 2 hydrogel cage. In addition, on the basis of the results of photocatalytic degradation and recycling experiments, excellent performances with respect to self-cleaning, regenerative ability, and easy recovery, were shown for this HEC-TiO 2 -CMC cage material, which demonstrated ideal application potential for MB removal.
