Heterogeneous photocatalysis mediated by semiconducting TiO 2 has attracted continuous
interest during the past decades and has shown great potentials in environmental …

Titanium dioxide (TiO2) stands out as a versatile transition‐metal oxide with applications
ranging from energy conversion/storage and environmental remediation to sensors and …

Bismuth oxyhalides (BiOX) nano-materials are considered to be the most encouraging
candidates to deal with environmental remediation, energy conversion, and degradation of …

The growing world energy consumption, with reliance on conventional energy sources and
the associated environmental pollution, are considered the most serious threats faced by …

In this work, we report the feasibility to achieve high lithium storage capacity and rate
capability of Co 3 O 4 anode materials by preparing hierarchically mesoporous structure …

Photoluminescence (PL) spectroscopy was used to infer that oxygen adsorption changes
the band bending of the anatase phase of TiO2 within P25 nanopowder in different ways. On …

Titanium dioxide (TiO 2) nanoparticles were successfully synthesised using a modified sol-
gel method with titanium (IV) butoxide (Ti (OBu) 4) as a precursor. The sol-gel derived TiO 2 …

Photoluminescence spectroscopy was employed to observe electron transport between
TiO2 particles. Ultraviolet (UV) irradiation (3.88 eV) was shown to positively enhance the …

Optical properties of metal oxide nanoparticles are subject to synthesis related defects and
impurities. Using photoluminescence spectroscopy and UV diffuse reflectance in …

Jiang et al. present the photoluminescence (PL) spectrum of the nanoparticles before and
after hydrogenation. While we do not wish to dispute the general conclusions of this work …
