Electrospun CdS–TiO2 doped carbon nanofibers for visible-light-induced photocatalytic hydrolysis of ammonia borane

One-pot synthesis of CdS sensitized TiO2 decorated reduced graphene oxide nanosheets for the hydrolysis of ammonia-borane and the effective removal of organic pollutant from water

“…CdS has a relatively lower band gap (~2.4 eV) which is helpful to absorb the light at wavelength of ˂ 510 nm. When the TiO 2 is sensitized with CdS, the photo generated electrons move from CdS to TiO 2 , whereas the photo generated holes remain in CdS [3,12]. This charge-carrier separation restrains charge recombination, thereby improving the photocatalytic activity of TiO 2 .…”

“…Hydrogen energy is considered as a green and pollution free as compared to petroleum products. Recently, ammonia borane (AB) has been identified as a desirable solid hydrogen carrier for hydrogen storage applications due to its high hydrogen content (19.6 wt%) and potential regenerability [3]. Most importantly, AB is nontoxic, stable, 3 environmentally benign, and can be handled safely, which greatly facilitates its applications.…”

“…Recently, hydrolysis of AB has been regarded as a popular and efficient route due to its rapid hydrogen release and green process with catalysts [3,4]. Indeed, nobel metal catalysts exhibit high catalytic activity; however, the development of efficient, low cost and stable catalysts is very important for practical application to overcome the high cost of the reported precious metals.…”

Preparation and photocatalytic activity of fly ash incorporated TiO2 nanofibers for effective removal of organic pollutants

“…Hence increasing the efficiency of visible photocatalysis is important for the practical application of this technique [9][10][11]. Various attempts have been made to develop the visible light activity to TiO 2 such as doping with metal and non-metal ions [12,13], dye sensitization [14], and semiconductor coupling [15,16] etc. TiO 2 is one of the most studied materials in the field of antibacterial applications.…”

Carbon quantum dots anchored TiO2 nanofibers: Effective photocatalyst for waste water treatment

“…However, large band gap (3.2 eV), which accounts for merely 5% of the solar photons, limits its photoresponse to ultraviolet light, thereby hampering its wide use [8]. Many studies, such as coupling with small band gap semiconductor [9,10], dye sensitization [11], and doping with metal and non-metal ions [12,13] have been carried out to develop the visible photocatalytic activity of TiO 2 .…”
