Surface enhanced Raman spectroscopy based on Ag@mZrO2@Ag nanocomposites: Sensing and photocatalytic reduction of chromium(VI)

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

“…However, its bandgap typically falls within the range of 5-7 eV, limiting its ability to absorb light to the UV spectrum and resulting in poor solar light-harvesting capability. [16][17][18][19][20] Additionally, the high recombination rate of photogenerated electron-hole pairs poses a challenge to its potential use in photocatalytic applications. To enhance the photocatalytic efficiency, researchers have developed a variety of strategies, such as constructing heterojunctions, adjusting artificial defects, and surface modification.…”

“…To date, ZrO 2 /g-C 3 N 4 composites have been widely developed for the photocatalytic degradation of organic pollutants; 15,19 however, these composites generally involved solid ZrO 2 materials. As we know, there are few reports on composite photocatalysts combining hollow ZrO 2 nanospheres with g-C 3 N 4 sheets.…”

Fabrication of core–shell AuNP@UIO-66/Au nanoparticles for in situ SERS monitoring of the degradation process

“…Li et al successfully prepared single Au-coated AgNWs (Ag@AuNWs) using a laser-assisted pulling method. [5][6][7] The resulting Ag@AuNWs were used for SERS monitoring and assessment of the plasmon-driven catalytic reaction of 4-nitrothiophenol to 4,4 0 -dimercaptoazobenzene. 8 However, these bifunctional nanoparticles were synthesized using multistep preparation processes or under strict conditions.…”
