A noble bimetal oxysulfide CuVOS catalyst for highly efficient catalytic reduction of 4-nitrophenol and organic dyes

“…Among the methods used, photocatalytic degradation, adsorption, membrane occulation, ltration, and reduction technological applications are reported by different scholars. [13][14][15][16][17][18][19] Sun et al used a carbon microsphereloaded copper-based catalyst for the degradation of organic dyes in aqueous solution. 20 Liu et al also studied the synthesis of various NiCo 2 O 4 structures to degrade organic dyes under microwave catalysis.…”

Synthesis of a hierarchical structured NiO/NiS composite catalyst for reduction of 4-nitrophenol and organic dyes

“…[29][30][31][32] Recently, technological applications such as adsorption, photocatalytic degradation, chemical oxidation, membrane ltration, occulation, and reduction have been used to remove organic pollutants and decolonized wastewaters. [33][34][35][36][37][38] Still now, the development of cost-effective, environmentally benign, and efficient techniques is an important concern in the eld of environmentology. 39,40 Recently, the reduction of organic pollutants has been carried out by metal nanoparticle (like, Ag and Au) based catalysts.…”

Visible Light Responsive Metal Oxide Photoanodes for Photoelectrochemical Water Splitting: a Comprehensive Review on Rational Materials Design

“…Recently, Na doped WO 3 photoanodes were found to extend the light absorption edge [80] . In the presence of [PMo 12 O 40 ] 3or [PW 12 O 40 ] 3as molecular OECs, the 0.4at% Na-doped WO 3 photoanode exhibits an impressive photocurrent density of 4.5 mA/cm 2 at 11.1 V vs RHE under AM 1.5 G illumination. Creating oxygen vacancies and low oxidation state of tungsten ions (e.g.…”

“…Photoelectrochemical (PEC) water splitting that uses man-made materials to emulate natural photosynthesis (NP) for solar hydrogen (H 2 ) production, providing a potentially economical way to convert solar energy into clean H 2 fuel, which has attracted great attention since its first discovery in the 1970s [4][5][6][7][8] . In the past decades, the PEC water splitting technique has also been derived to other applications such as pollutant degradation [9][10][11][12] , CO 2 reduction [13][14][15] , and value-added chemical production [16][17][18] . However, the derived applications are beyond the scope of this review, thus we will not discuss in detail.…”
