The major indoor air pollution-formaldehyde has been a serious threat to our lives to our lives, and accordingly the formaldehyde degradation has turned into a concerned issue of public. This paper has based on a number of degradation methods and combined the adsorption effect of activated carbon with the catalytic effect of MnO2 to remove formaldehyde. The results show that the Nano-MnO2 particles loaded the surface of activated carbon particles possesses smaller sizes, better dispersion and no agglomeration, and consequently the AC/MnO2 compounds degraded formaldehyde effectively.

In this paper, the plasmid stability and the concentration of recombinant E.coli DH5α were investigated by adding glucose of different concentration at the beginning of fermentation. The result shows that glucose was good for the growth of recombinant E.coli DH5α and the stability of plasmid. The optimal concentration of glucose was 1g/L. The biomass concentration could be up to110.930g/L and the fraction of plasmid-carrying cell was about 99% in the optimized culture medium.

Gaseous Formaldehyde

As a major indoor air pollutant, formaldehyde released from building and furnishing materials is one of the main volatile organic compounds (VOCs). Hierarchical TiO2 nanotube arrays (TiO2 NTs) prepared via a facile two-step anodization showed excellent photocatalytic (PC) degradation of formaldehyde at room temperature. Modification with noble metal nanoparticles (NMNs) could further improve the PC activity of TiO2 NTs. The final products of formaldehyde degradation were detected to be CO2 and H2O, which indicated that the mineralization of formaldehyde was the major process in this PC reaction. The reaction rate constants (k) determined for the three catalysts were in the order kTiO2 NTs < kAu/TiO2 NTs < kPt/TiO2 NTs (Pt/TiO2 NTs had the highest PC ability). The significant enhancement of PC performance can be ascribed to the formation of a Schottky junction between the NMNs and TiO2 NTs.
