Synthesis of environmentally benign ultra-small copper nanoclusters-halloysite composites and their catalytic performance on contrasting azo dyes

A Nanohybrid Containing Cyan‐Emitting Copper Nanoclusters and TiO2 Nanoparticles: Tuning of Optoelectronic Properties

“…have demonstrated photo‐reduction of CO 2 to methanol by Cu‐ZrO 2 composites, [33] whereas Deb et al . used Cu‐halloysite nanotubes to degrade MB and MO dyes [34] . Hao et al .…”

“…Yu et al have demonstrated photo-reduction of CO 2 to methanol by Cu-ZrO 2 composites, [33] whereas Deb et al used Cu-halloysite nanotubes to degrade MB and MO dyes. [34] Hao et al and, Kang and co-workers have reported photo-current response of their TiO 2 À Cu NC composites. Hao et al observed a maximum of 0.4 × 10 À 3 mA of photocurrent in the composite system.…”

Halloysite Nanotubes: Smart Nanomaterials in Catalysis

“…Recently, Rahman et al reported for the first time the stabilization of copper nanoparticles onto HNTs support by their seeding in mild conditions [93]. To achieve this purpose, glutathione was considered as both a reducing and a stabilizing agent for the synthesis of Cu nanoparticles, obtaining two different nanocatalysts called CuNCs@HNT and CuNCs@HNT-PS, respectively, depending on the synthetic pathway considered (one pot synthesis for the first one, post-synthesis for the latter).…”

Manipulation of the halloysite clay nanotube lumen for environmental remediation: a review

“…[21][22][23][24][25][26][27][28][29][30] These reviews mainly focus on the excellent support function of the outer wall of clay nanotubes, which is related to its elongated nanorod (NR)-like shape. For example, various metallic NPs such as Cu, ZnO, α-Ni(OH) 2 , Co 3 O 4 and CeO 2 -WO 3 , [31][32][33][34][35][36] or functional organic molecules such as cucurbiturils, chitosan, polyaniline, hydrothermal carbon, organosilane and dopamine, [37][38][39][40][41][42] were supported on the outer wall of clay nanotubes to prepare advanced hybrid nanomaterials, and then used as high-…”
