Fabrication of 2D SnS2/g-C3N4 heterojunction with enhanced H2 evolution during photocatalytic water splitting.
TL;DR: The obtained PL spectra, photocurrent and EIS spectra show that the enhanced performance for H2 generation over the heterojunctions is primarily ascribed to the rapid charge transfer arising from the suitable band gap positions leading to an improved photocatalytic performance.

Directing the amount of CNTs in CuO–CNT catalysts for enhanced adsorption-oriented visible-light-responsive photodegradation of p-chloroaniline
N.F. Khusnun,Aishah Abdul Jalil,Sugeng Triwahyono,C.N.C. Hitam,N.S. Hassan,F. Jamian,Walid Nabgan,Tuan Amran Tuan Abdullah,Mohd Johari Kamaruddin,Djoko Hartanto +9 more
TL;DR: In this article, the catalysts (CuO/CNT) were characterized by XRD, nitrogen adsorption-desorption, ESR, FTIR, Raman, and XPS spectroscopy, showing that a lower amount of CuO was dispersed well on the CNT, while higher loading was agglomerated, producing large-size crystallites, hence resulting in lower specific surface area.
Journal ArticleDOI
Synthesis of a Zinc Oxide Nanoflower Photocatalyst from Sea Buckthorn Fruit for Degradation of Industrial Dyes in Wastewater Treatment.
TL;DR: The results indicate that SBT-ZnO/NFs as synthesized is an inexpensive, non-toxic, rapid, and reusable photocatalyst that can play an enhanced role in wastewater treatment.

Band gap engineered TiO2 nanoparticles for visible light induced photoelectrochemical and photocatalytic studies
Mohammad Mansoob Khan,Sajid Ali Ansari,Debabrata Pradhan,M. Omaish Ansari,Do Hung Han,Jintae Lee,Moo Hwan Cho +6 more
TL;DR: In this article, an electron beam treatment of commercial TiO2 (p-TiO2) nanoparticles was used to obtain visible light-active nanoparticles, which exhibited a distinct red-shift in the UV-visible absorption spectrum and a much narrower band gap (2.85 eV) due to defects.

Conducting PANI stimulated ZnO system for visible light photocatalytic degradation of coloured dyes
R. Saravanan,Elisban Sacari,Francisco Gracia,Mohammad Mansoob Khan,Edgar Mosquera,Vinod Kumar Gupta,Vinod Kumar Gupta +6 more
TL;DR: In this paper, the polyaniline (PANI)/ZnO nanocomposite system exhibits superior degradation of methyl orange and methylene blue under visible light condition, due to the intermolecular interaction between conducting PANI and ZnO nanoparticles.
