Sulfur Vacancy-Enriched Rhombohedral ZnIn2S4 Nanosheets for Highly Efficient Photocatalytic Overall Water Splitting under Visible Light Irradiation

“…More importantly, the absorption tail of ZnIn 2 S 4 -800 is significantly higher than that of ZnIn 2 S 4 . The reported studies indicate that the absorption tail is generally associated with various defects, − so the UV–vis diffuse reflectance spectra further confirm the presence of rich sulfur vacancies and are consistent with the EPR results. The calculated band structure (Figure S10) and “Tauc’s plot” (Figure b) indicate that both samples are direct band gap semiconductors.…”

Initiating highly efficient (Bi,Ce)2(O,S)3−xoxysulfide catalysts with rich oxygen vacancies for hydrogen evolutionviaadjusting valence band configuration

“…Cui et al 34 studied V O -lled BiOCl for its photo-oxidation properties in terms of V O . The oxygen vacancy (V O ) provides active sites that can act as temporary trapping sites for the photo-induced electrons, resulting in a decrease in the electron-hole recombination rate, [35][36][37][38] The oxygen vacancy defect was used as the adsorption site of the H 2 O molecule to result in the formation of active oxygen via oxygen trapping and O-H bond weakening of the adsorbed H 2 O molecule. 23,39,40 There have been a few studies on bimetal-chalcogen catalysts to investigate the improvement of hydrogen evolution by V O .…”

Inventions, innovations, and new technologies: Solar Desalination

“…This technology is highly effective in the treatment of hyper-saline brine that cannot be desalinated by conventional reverse osmosis (RO) technology. Although vast variations of materials are tried out as solar absorber/evaporator surfaces, wood-based materials have gained high interest because of the naturally occurring favorable properties, such as porous structure, hydrophilicity and low thermal conductivity [7][8][9][10][11][12][13]. Also, they are cost effective and sustainable.…”
