Synthesis, characterization and photocatalytic activity of porous manganese oxide doped titania for toluene decomposition

Degradation of nitrobenzene using titania photocatalyst co-doped with nitrogen and cerium under visible light illumination

“…Tel. : +86 738 8325200; fax: +86 738 8325200. suppress the recombination of photo-induced electron-hole pairs when migrating from the inside of the photocatalyst to the surface [6,7,9,10,[13][14][15][16][17][18][19].…”

Application of a hybrid system comprising carbon-doped TiO2 film and a ceramic media-packed biofilter for enhanced removal of gaseous styrene

“…Styrene, for example, is used extensively in the production of plastics and rubbers, and many workers are exposed to harmful gaseous styrene in the workplace. Low concentrations of gaseous styrene are known to cause carcinogenic, mutagenic, and teratogenic diseases [1]. In USA and EU styrene exposure concentration limit is 210 mg m −3 (50 ppm) for an 8-h time-weighted average (TWA), while the recommended concentration ceiling exposure for styrene is 850 mg m −3 [2].…”

Photocatalytic degradation of aniline with boron-doped cryptomelane type manganese oxide

“…Higher photocatalytic activities of oxides could be obtained by metal doping such as Ce [12] and Ti [13], and it could also be obtained by non-metal doping such as N [14,15], S [16,17], P [18], and C [19,20]. Recently, boron-doping on oxides begins to attract attention in electrochemical and functional materials application [21].…”
