Emerging contaminants in the aquatic environment have become a worldwide problem.
Conventional wastewater treatment processes are ineffective for eliminating the emerging …

Titanium dioxide (titania, TiO 2) has been fervently researched over the past few decades
due to its potential applications across many different areas. Thanks to its bulk properties …

A hydrothermal technique was used to create a CoFe 2 O 4/ZnO (CFO/ZO) nanocomposite
for the photoreduction of hexavalent chromium. To boost the photocatalytic efficiency of the …

Hybrid nanostructures and nanoarchitectures possess unique physicochemical properties
such as high activity/functionality, enhanced physicochemical stability, and improved …

Despite the photocatalytic organic pollutant degradation using ZnO started in 1910–1911,
many challenges are still ahead, and several critical issues have to be addressed. Large …

A fast and low-cost sol–gel synthesis used to deposit a shell of TiO2 anatase onto an array
of vertically aligned ZnO nanowires (NWs) is reported in this paper. The influence of the …

Novel composite photocatalysts composed of reduced graphene oxide (RGO) sheets, CdS
nanoparticles (CNPs), and ZnO nanorods were developed using a simple low-temperature …

The present study focused on the degradation of malachite green (MG) dye which is
extensively used in the aqua-culture and later disposed in water bodies. In order to treat the …

Abstract TiO 2, ZnO, and SnO 2 metal oxides were synthesized by the sol-gel method and
heterojunctions were fabricated by combining TiO 2 with either ZnO or SnO 2 in a 1: 1 ratio …

As an alternative to TiO 2 photocatalysts, ZnO exhibits a large potential for photocatalytic
(PC) applications in environmental treatments, such as degradation of wastewater …
