Promising pure gold aerogel: in situ preparation by composite sol–gel and application in catalytic removal of pollutants and SERS

Femtosecond laser composite manufactured double-bionic micro–nano structure for efficient photothermal anti-icing/deicing

“…In nature, surface contamination will not only weaken the photothermal property of functional film surfaces, but also further trigger the heterogeneous nucleation of droplets. 47,48 Therefore, self-cleaning performance is of great importance to a photothermal superhydrophobic anti-icing/deicing strategy. Thus, 10 repeats of sand covering and self-cleaning experiments on MNHF were carried out to verify its self-cleaning performance.…”

Polyacrylonitrile as a versatile matrix for gold nanoparticle-based SERS substrates

“…[24][25][26][27][28][29][30][31] However, synthesizing AuNPs has always been challenging due to the tedious routes and use of harsh chemicals. [32][33][34][35][36][37][38] Here, gold nanoparticles (AuNPs) are synthesised from gold chloride hydrate (HAuCl 4 $3H 2 O) using a simple and straightforward approach utilizing dimethylformamide (DMF). [39][40][41] Using DMF as a solvent and reducing agent, it has been previously shown that the metallic nanostructures of gold, silver, and other metals can form in various ways.…”

Rational design and easy fabrication of transparent photothermal/hygroscopic composite coatings with long-lasting antifogging performance under sunlight activation

“…[18][19][20][21] Common photothermal materials encompass carbon materials (carbon nanotubes, 22 graphene and its derivatives, 23,24 etc. ), plasmonic metallic nanoparticles like those of Au and Ag, [25][26][27] black metal oxides (ferric oxide, 28,29 copper oxide, 30 etc. ), and black polymers such as polydopamine 31 and polypyrrole.…”
