Fabrication of recyclable reduced graphene oxide/graphitic carbon nitride quantum dot aerogel hybrids with enhanced photocatalytic activity

Abstract

Recyclable photocatalysts that can efficiently respond to visible light must be developed for practical application.

Effect of concentration of glycidol on the properties of resorcinol-formaldehyde aerogels and carbon aerogels

“…Due to their controllable density and nano-scale homogeneous microstructure, aerogels possess interesting chemical and physical properties, such as ultra-low density, ultra-high specific surface area, ultra-high porosity, ultralow thermal conductivity and so on. 1 In recent years, many researchers have focused on the investigation of SiO 2 aerogels, 2 resorcinol (R)-formaldehyde (F) aerogels and carbon aerogels (CAs), 3,4 graphene aerogels, 5,6 3D MoS 2 aerogels 7 and so on.…”

Boosting Tetracycline Degradation with an S-Scheme Heterojunction of N-Doped Carbon Quantum Dots-Decorated TiO2

“…C 1s, N 1s, and O 1s atoms associated with 0D material were detected in the XPS survey spectrum, showing all expected elements existed in the N-CQDs structure (Figure S2a). In the high-resolution C 1s XPS spectrum, three main peaks were assigned as CO/CN, C–O/C–N, and CC at binding energies of 288.5, 286.0, and 284.5 eV, respectively (Figure S2b). In parallel to this, the peaks at 531.8 (CO) and 533.1 (C–O) eV were observed in the deconvoluted O 1s XPS spectrum (Figure S2c).…”
