Multifunctional Ni(OH)2/Ag composites for ultrasensitive SERS detection and efficient photocatalytic degradation of ciprofloxacin and methylene blue

Polymethylacrylic acid-induced fabrication of hollow hZrO2/g-C3N4 composite photocatalysts: study on solar photocatalytic performance and mechanism insight

“…7–10 Photocatalytic processes typically involve three fundamental steps: first, semiconductors absorb effective photons, generating electron–hole pairs if the energy of photons ( hν ) equals or exceeds their bandgap ( E g ); second, the photogenerated electron–hole pairs rapidly separate and migrate aided by the internal electric field; finally, a series of reactions involving photoproduced holes and electrons takes place on the semiconductor surfaces. 11–15…”
